They never answer their phones. EVER. I don't know how businesses can run or survive that operate in that way.

I have used them for alarm installation and for car audio installations on multiple cars over the years and they did a great job in each case. read more

The quality of care and service from this place is fantastic! They installed an Alpine Halo9 iLX-F309 in my 2003 Porsche Cayenne S and did a fantastic job. My brother recommended them, who had them install the same stereo on his 2002 BMW 525i. I highly recommend using these guys. They are way more focused on the quality of their work than other shops I have used in the past. Thank you, Custom Car Alarms and Team, James @ Oakmont Auto Care. read more

Avoid this shop at all costs. I wasn't going to leave a bad yelp review. But today's revelation was my final straw. I'll try to keep this short and simple. But we all know how that'll go. 1) I brought my car on the day I was told by Mark. The car was already stripped on the inside. Meaning I'd see the work after completion + their job is that much easier. I would stop by 1-2 times a week after work for fun to see the progress and bs with Mark. I didn't have a deadline and always expressed this to Mark. I wanted quality with no rush. My car sat with nothing done to it for weeks. Each visit was an excuse why they hadn't started the work. During these visits and bs'ng I shared my bad experience at another shop years back. Unknowingly he would do the exact same thing to me. I gave him the benefit of the doubt and was excited to see the results since I sacrificed urgency 2) Got the car back and maybe 30% of what I asked for was done. sloppy & lazy work + I can see ALL of it since no interior panels. Not sure what they were thinking. Brought the car back for them to "make it right". I provided a few interior panels to help in tolerances for the sound deadener. I was clear about not wanting/needing the panels to be installed. You'd think not installing would benefit them anyways. What did they do-They installed a panel that's hard to remove in the hatch. I had my suspicions they didn't apply deadener under that panel. They had applied it on the passenger side in the same spot. Since I didn't provide that panel, I could easily see. Keep in mind this is a simplified version of the story. A story of complete incompetence and lies. Fast forward to today. I had the time and will power to remove that panel. No deadener. Each interaction I'd tell Mark that I'm not looking for value. I was extremely clear I wanted quality. All of it fell on deaf ears unfortunately. Terrible terrible shop. Multiple times I was clear that I was judging them on this job to determine if I'd bring more work to them. Summary: -they took forever even though I told them another shop did this tome and I was not happy -they did a terrible job even though I repeatedly told them I was not looking for value. I wanted quality. -they took the car back to fix it and "make it right" which they did fine. But installed a panel and blatantly lied about deadening underneath it. I remembered another issue. I was clear I wanted 2 wire battery relocation. Negative + positive. He did just the positive and told me the numbers (ohms volts or whatever) worked out fine and I don't need a negative wire. That's not what I agreed on. Not what I agreed to pay for. No communication with me he was making this decision. This is just a crappy shop. I'd stay away read more

Great customer service and use quality components. I'm super happy with all my systems Custom has done with all my cars. I've had 4 large sound systems done by them and wouldn't go to any other spot. read more

After seeing good reviews, we decided to check this business out. Our son wanted to install a new stereo and a back up camera into his 2006 Honda. We were shown the options and he made his decision. An appointment for the install was set up for a few weeks down the road and it turned out great. He figures speakers are next, so we'll be back. read more

I wanted to share my experience at this shop. I own an older Honda, not worth much, just sentimental value. Recently other cars like it have been targeted by thiefs for the catalytic converter. So I decided to get an alarm. Jesse originally helped me out, he was really cool. Understood I was on a budget and really worked with me and scheduled the appointment. When I brought in my Honda Jesse started working on it immediately and Mark the manager assisted me in the lobby. I ended up upgrading my alarm and even got my factory speakers replaced. Again, mark worked with me on my budget. Really great guys, from the work you can tell these guys are perfectionists. And from the way they interact and talk to you it shows they care about taking care of you whatever you drive. read more

This type of shop used to thrive in the 80s and 90s but now with cars all coming standard with car alarms and decent audio systems, I'm sure it's had a negative impact on the volume of business that they do. Nice set of folks focused on providing a great customer experience. I would highly recommend going here, especially if you were trying to support your local small business. read more

If you want QUALITY "Products" and "Services" Custom Car Alarms is your answer. Many many years ago I went to them for an alarm system and was very satisfied. Today, the same top notch products and services is still exist. In regards to cost, they are reasonable especially for what you get. To me, I'm willing to pay for better products/services anytime. I wanted to surprise my wife and kids with upgrading our 2003 Honda Odyssey stock Radio/CD audio system to the latest system that can interface with our iPhones. My requirements were the following: Aux jack, USB, Phone call receiving, Blue tooth, Radio, CD player, and detachable system face. Jessie McLain was our sale rep who helped me select a system that was perfect for our needs. He was able to get me in the schedule and finished as promised. Additionally, Jessie walked me through the system operation and provided me with additional tips on usage. Jessie is a true professional in his craft and very honest person. I value that type of person which makes purchasing much easier. If only other business can follow this model, they too will prosper. Overall, Custom Car Alarms is my go to Audio and Alarm installer company. Again, the products and "honest" services along with good pricing makes them the best place in Northern California. I recommend them to all my friends and family. Thank you Jessie for a job well done and Custom Car Alarms for keeping your standards of quality products and services to its upmost best. read more

I first saw these guys back in the late '80's. My first visit was two years ago for a simple head unit. Mark was nice, knowledgeable and helpful. No sales pressure. Good enough that I just returned to complete my system. I told him what I wanted and he got it done for a real good price. It's worth saying again that there was no pressure to change my list. He provided exceptional service. There was a couple of slight, very minor issues with the dash fitment and the loss of steering wheel controls that I noticed after leaving. Upon rescheduling, Mark went above "good" service to make it right. I gladly offered to decline his generosity but you can guess that didn't happen. I left with a smile that comes with great customer service. I waited until after my appointment to fix the issues before writing this review. I would've given them a nice review anyways, but this experience deserves 5 stars. I recommend them. read more

Mark and his team provide great clear service, competitive pricing, and what they say they'll deliver - they deliver. No BS. I love the shop for all things, custom car audio an alarm related. read more

My commute is a JOY now thanks to Custom Car Alarms! I love my '10 Rav-4 but bought it before backup cameras, screens and such were standard. So instead of buying a new car, I came here to help bring it into this decade. They set me up with a rear camera and a stereo panel (connects to my phone for music, maps, messages etc) and added sound deadening material to the floor and front doors, all for a very reasonable price (much cheaper than buying a new car). Took the day to install. Such a nice experience. And now instead of cranking the volume up on the freeway, I find myself having to turn it down! I wish I had done this sooner. read more

Mark pulled off the impossible on my old Toyota Solara. The dash piece was stuck and impossible to remove to install a new Bluetooth screen. He managed to do it without breaking the whole thing. He kept me constantly updated. He's my HERO. Easy to work with. I'm very impressed. I will recommend this company to everyone. read more

We took our sons pickup truck in for an alarm. Waiting area and selection was nice. Mark and the other gentleman (can't recall his name) were both very friendly and helpful. They didn't try to over sell anything to us and even put in new dash lights (that we had previously bought) so that we didn't have to try to figure out how to take the dash off and do it ourselves. GREAT Customer service is hard to find today and these guys have it figured out. Highly recommend them to anyone looking for alarms or stereos. read more

The Car radio finally gave out...so was looking for a quick and cheap radio to get installed without a lot of fuss. These guys were very professional and the install looks great! I did have to wait a few days for the kit to come in, but I love it! Super nice to have Bluetooth in my older car now. read more

Super nice guys. My car audio install was both more expensive *and* less expensive than expected: more because the speakers *I* had gotten from Best Buy didn't fit and CCA's speakers were more expensive (and better...); less expensive because they refused (read: strongly suggested against) to install the BestBuy head unit because the install kit looked incorrect (they were right: it turns out that a Mini Cooper Countryman is not just a larger Mini Cooper and the Best Buy install kit wouldn't fit). Then they provided, let's say, very favorable pricing on the install after I kept returning after I said I would complete the install (and then didn't do it). Just headed out. Got a call 10 minutes later saying "Hey, did you leave a $20 bill on the ground when you left?" "No, I don't think I did. In any case, if I did, buy a beer on me...". Good guys. I'll happily refer anyone to them. read more

Store is well kept and stocked with high-end products. Mark was attentive and did not upsell me on anything. The workmanship was clean as was the sound ; ) I changed out stock speakers to JL plus amp. read more

I've used them at least 4-5 times over a long period of time. Zero problems. Perfect work. Alarms, stereo, and cameras. Pure professionals. I feel sorry for the guys that try to bust into the cars I've had, they're not going to match Custom Car or even come close. read more

Mark is great! We set up a time for me to come in and he gave me an expectation on time to get the job done. They exceeded their time quote and got me in and out in half the time! Going back for lighting work next! If you have any alarm, lighting, or stereo work I would highly suggest these guys! Bay Area staple! read more

I have to say, Mark hooked me up! I wanted a new system in my car. He sold me what I needed, not what he could've sold me. Another place quoted me over $4k with a bunch of stuff I didn't need. I definitely recommend Custom Car Alarms as they have integrity, and didn't try to screw me over to make money off of me, and they saved me $2k that I knew I didn't need to spend. Mark also kept me updated weekly when there were shipment delays, which I appreciated! He also went an extra step further and fixed my key remote that was busted. Nice touch! My car sounds AMAZING now! I highly recommend Custom Car Alarms! read more

I just bought a Mercedes, the owner brought all of his cars here for high end audiophile quality stereos. Unfortunately, I had to take all of that equipment out. But the reason for my review is that the quality of installation and attention to detail on this particular car was unlike anything I had seen in 25 years in the automotive business and stereos. Completely amazing sound, outstanding custom craftsmanship. Just really incredible work that I would not have noticed unless I was taking the stereo out. Just wanted to give credit to these guys. The car audio world is filled tradesman Its very rare to find actual craftsman. Big difference between the two and these guys hold that distinction in my mind. read more

This review is an accumulation of all my interaction with them. I can't point out just one person because all the staff members there are awesome. This is my go to spot for troubleshooting any auto audio and security needs. They were able to troubleshoot my remote trunk release connected to my Viper alarm, installed my Python alarm that I pulled from the old car to the new car we got and able to have components for my diy installs I do. read more

I've had three business transactions with this company. 1) They installed a sub-woofer/amp I purchased on my own. This was an install-only job. They did it happily, quickly, and reasonably. 2) We needed a cable for my girlfriend's car. It was complicated & something beyond our own doing. Again, they did it happily, quickly, & reasonably. 3) I needed some cables (less than $10). They proved the cables, & then some, happily, quickly, and reasonably. read more

Super happy with the compact subwoofer/amp installation in the trunk of my MINI convertible. The guy at the front desk (I didn't get his name!) as well as Patrick the installer has friendly, helpful, prompt and on time. The pricing was very fair. The work was done flawlessly and now my little car sounds kickin'. The showroom was comfortable and well-stocked. I'd recommend to anyone. read more

If you've ever driven down CCB in Pleasant Hill you've likely seen the collection of cars, trucks and even boats lined up at Custom Car Alarms. There's a reason this shop is always hopping! Mark and his crew know their stuff--from basic alarm installs to exotic custom sound and video systems worthy of a home theater. They do all the work on my Jeep, and I can't say enough about their service, knowledge, and sound advice. (See what I did there?) And the best perk: they stand behind their work 100%. Lots of shops make that claim, but this crew owns it! Plus, they always have the coolest new toys. I'm pretty sure they could trick out a Space X rocket if one ever rolled up. The Dins says check 'em out read more

These guys are very professional, the whole staff knew exactly what they were doing. i came here to install HIDS on my 2015 Subaru outback. they did fantastic job. i will definitely come back here again if i have too. read more

Bought a SiriusXM satellite radio to add to our listening pleasure along with the already cool stereo/cd player the car had in place. Thinking this would be easy-peasy to install ourselves....he he... So after purchasing this item at Best Buy with minimal help, I get home and realize this could be done, there are cords....many cords. And the placement of this device was a big issue I hadn't thought out well either. I call back Best Buy and they tell me a week to get it professionally installed. Nope. Leaving shortly for LA. And why would I want to purchase an item and them wait a WEEK to have it installed? I understand something can't be done the same day, but a week? So I started my search for alternate options. Saw a few other stereo installation places, no answer. Then I was referred to Custom Car Alarms through another place that no longer did stereo installs. I took the time to look it up on yelp, then I took a chance on a Friday at 11:30 ish, and called.... A very nice friendly guy named Mark answered, and I explained our dilemma about placement and wires...blah blah blah. He said "no problem", and if I could bring it down at 2 pm we can look at it together and figure out the best placement for it. Hello?! 2 pm today? Why yes that's what he said, well okay! Now he did inform us that it could take anywhere from an hour to an hour and a half, and they charge $90 an hour. But you know I did have a bad experience with Best Buy in the past where they forgot to give me a remote for a stereo after install, and trying to get anyone on the phone to find it was a total nightmare. (I ended up calling corporate and they took care of it and made it right) But I was a bit gun shy to use them again and plus a week just wasn't going to work for me. So I didn't mind spending more to get the job done right and all the wires tucked away neatly. They got me in right away and were super friendly and professional. read more

Needed Bluetooth for my 2006 Lexus so I could have my music bumpin. I was playing the music through a tape adaptor it was horrible! I called these guys up and they were super friendly and knowledgeable. They hooked me up with an integrated mp3 adaptor that was super reasonable in price. I didn't have to pull out or change any existing components. They got me in early due to a cancellation and it's worked great ever since install. I even waited to post this review to make sure. I will be back for any car stereo needs!! read more

These guys are great. They have installed a viper system on all of my cars and so far so good. One time dealership was pointing fingers at them for faulty installation and they helped us out free of charge to disconnect and connect the alarm. I personally don't think they did anything wrong as the car was fine for 6 months after their installation so I think the dealership didn't know what was the problem and started pointing fingers at others. Anyway I will be back with my next fleet car. Mark is great and always takes good care of me. Do make an appointment before you go. They get busy sometimes. read more

Great guys. Excellent work. Better pricing. 10/10 would have them install my car stereo again.

I read tons of reviews before taking my 06 Limited Edition Charger to Custom Car Alarms and Mark and his team did not disappoint. Mark was patient and consultative while educating me on my options. The install appointment was just a couple days out and went off without a hitch. The install was done in about an hour while I hung out at Starbucks across the street. Most importantly, my new system sounds great and is easy to use. All around a fantastic experience with Custom Car Alarms! read more

Custom Car Alarm is the best shop I been to by far. They take good care of you and stand by their work. Their staff/technicians are awesome, I plan on having more work done to both vehicles and with have them work on it. Thanks again for all you do and hope you all have a good one. Roy read more

It's nice to know that a service focused custom car audio shop still exist. Custom Car Alarms is the standard bearer for that type of establishment. I have had my 96 impala as well as my mk4 Supra worked on by them and I'm always impressed by the results beyond what I expected walking in. They treat your project like it's theirs. They would call me throughout the process of installation, if the plan was going to need to be deviated in any way. To me, that's showing that you're as invested in the car owners vision as they are. read more

I went to Custom Car Alarms in January to install my Blackvue dashcam. Once inside the store, it reminded me of my youth. I fondly remembered my very first pull out stereo back in the early 1990s, a Kenwood KRC 810 that I saved up for. [OK, so I'm totally aging myself now.] I thought I was so cool walking around Serramonte in my high school uniform toting around this black "pulll out" bag with a Kenwood patch on it. I also remember my second car stereo, an Alpine 7525 (graduated to the face plate type). That one was also an excellent stereo. I had a couple other car stereos after that, but they never sounded as good as my first 2.. They just don't make them like they used to. Anyways, back to reality. I've become really particular about who works / installs mods on my little car. For example, I traveled to Livermore (from San Jose) to get my car tinted after quite some research. I'm very satisfied with the work on my tint. Still not sure how a 6+ ft tall man managed to put tint in the rear window of my little a3 sedan. But anyways, when I heard Michael has been in the car stereo industry for a few decades, I was more than intrigued. This guy must know what he's doing. Just like my tint guy, Michael is a master in his craft. I traveled from San Jose to Pleasant Hill just for a dash cam install and glad I did. The install on my dashcam (front and rear) was super clean! I'm so impressed with the work and the friendly service we received from the staff. I totally recommend! read more

Had a product installed in my truck today. Great job. Very nice employees and clean business. Cheaper than most other places and the installation came out beautiful. Thanks! Will be back. read more

NEVER will I recommend someone to Custom Car Alarms. I came here to have my Eclipse installed. Simple double-din install with back-up camera and bluetooth installation. I have never encountered such a sloppy installer when it comes to car audio. List of my headaches: Air con is totally out All power outlets are out Fresh air ventilation blows hot engine air Antenna installed on my BLACK dash with a GRAY felt pad looking thing (looks absolutely ridiculous) These are the problems that I am just now encountering. Who knows what other ones will surface as time goes on. I am waiting to see what these guys will do to correct this problem. I live in southern California and they are saying that the only way that they will fix this problem is if I bring my car back up. Do they not realize how FAR southern California is and BUSY people are?? In addition to this bullshit, they totally tried to up-sell me on some speakers that I apparently did not need. Initially we were quoted $2xx for the install which then jumped to $3xx. The install ended up closer to $500 by the time they were through with a basic routine double din install. The briefing on how to use the system was brief to say the least. This place is a total rip off with their rookie installers. I have seen installers at Best Buy do a better job. read more

This was a cool find. Needed a new stereo for the wifey's car and Custom Car Alarms came through. Didn't need anything too expensive or over the top, just a better than basic stereo receiver that has Bluetooth and works with an iPhone. Great service, awesome installation and explanation of the product. read more
