I highly recommend this place. I broke my old 15 years old remote control beyond repair so I had a new car alarm installed. I walked into their shop & was immediately entertained with respect, friendliness & professionalism. In 30 minutes the job was done and the price is right. You can wait inside their airconditioned shop or wait next door at the fruit juice shop. I did my research before going to this place, they recommended the best alarm product and priced reasonably. I am a happy customer and will definitely be back for a car music system installation. read more

Called on a Saturday for an estimate and they quoted me exactly what I was looking for. I went one week later and installed everything in my truck and it took a day but it was reasonable! Got the radio, side speakers, amps, box and subs done! It's been a week and there's been no issues and the sound quality is amazing! And they definitely got the best prices in the area that's for sure. Staff is friendly and very professional and know their stuff. So I'd recommend everyone to come here! Shoutout to Henry and Art! read more

Have been getting service from the owner Solo aka Dr Boom for over 10 years. He is always consistant with his quality of work, friendly, courteous and prompt with service. From tinting jobs, tire upgrades, sound systems and alarms he is THE BEST. read more

Another Excellent job by Henry & his crew on my rig. They installed a full Viair OBA compressor system, extra outlets, switches & air horns. Their work on my overland vehicle was spot on, clean work & fair prices. Recently I referred a friend for an audio upgrade & he was very happy with his work as well. I have no problem recommending Custom Audio Designs to any of my friends or family. There isn't anything they can't handle. read more

Really Disappointed, was hoping to get my radio hook up today, but it seem like they've forgotten about the appointment. I give this place 2 stars, because the initial interaction was cool, nice people, but maybe they just be more puntual. I pushed my other activity for this, kinda wasted my times. read more

Henry was awesome. Very professional... He installed a custom brake pedal that I had made so I could brake with my left foot. Amazing install... Definitely recommended... read more

Customer service was on point. Had my car in and out on time. I would recommend Custom Audio to anyone looking to install a stereo and speaker system to the car. Left the car clean and no trace of any wires. Sound system came out amazing. read more

So glad I found this shop. Great customer service, professional work, speedy service and aall at a fantastic price I reached out to several local shops looking for a quote to have a dash cam hard wired.

I will definitely be backwhen looking to upgrade my car"s audio/video system. read more

I just got my 2014 4Runner 2 weeks ago and needs to have an alarm installed. So I asked around work if anybody could recommend a shop. One guys told me to try the a shop in Alhambra but they had closed down. I'm really big on current yelp reviews before I decide to spend $$ at a business I decided to try the one closest to my house and had the best reviews was Custom Audio Designs! So I message the company that I needed an alarm installed and if I was able to come in that day. They responded back within an hour and was able to meet a Henry the owner later that day who showed me two different alarms that they install. Picked one and had it done in the time they said 1 1/2! I'm very pleased with their service and prices! Thanks guys! I'll be back if I need some audio work. read more

I came to this shop because of the great reviews on here. I purchased an amp, 2 10" subs along with a bass control. The pricing was reasonable & they were able to get it done in a couple of hours. They do top quality work, this is the place to go! read more

Messaged Henry through Yelp to get a quote on installing a back up camera, received a response in 15 minutes! Appointment was made all within the hour. Arrived on the dot for the installation and they took my car in right away, the whole process took 45 min - 1 hr and I just waited at the shop. Easy, quick, good quality, & great price, no BS! Lifetime warranty included. Def recommend their services :) read more

Let me start by saying henry is the best! Excellent customer service and great quality of work. I would recommend this to all my friends & family. read more

Great work on my old truck. Steve & Henry took care of me, even fixed my dash! It was already broken when I arrived, broke a little more when we took it out, some epoxy & wa-la, repaired! Great srvc!! read more

Henry and Art were great. Knowledgeable, reasonable, and very patient as I purchased an amp setup that was not compatibility with my vehicles factory setup from eBay. I ended up purchasing a whole new setup directly from Henry and they RE-installed it after days of trouble shooting trying to get the amp I purchase on eBay to work. They weren't happy until I was happy. This is one 5 star recommendation they truly earned. Thank you guys. read more

I recently had a stereo and amplifier placed in my car and I have to say they have the BEST CUSTOMER service.

Henry took care of me in putting in lights for my new 2018 Pacifica. We did HID for the low beams and LED for the fogs. His price was excellent and his service even better. We ran into some issues with the lights (passenger-side flickering) but he worked hard to make it right. He replied quickly in all our YELP messaging and checked in on me even after we got everything fixed. Henry has gained my trust and I'll go back to him for future needs. I appreciated especially when he told me the parts warranty but added, "Even after it expires, we'll take care of you and work with you." This is a good guy, folks. Don't hesitate to have him do your car work. Thanks, "boss!" :-] read more

What can i say about Henry and Art? Well the 5 stars speaks for itself. Time, effort , patience and explaining what can be achieve in the mini sound system that they set me up with. Super satisfied with customer service to giving me great pricing and custom labor on a 10 inch sub box that looks like factory. I will bring my other car here to work on a mini system on it. Please feel free to call or go there. Best go there cuz they don't pick up the phone much once they get busy. Again, thank you for the work and made 2 new friends! read more

Best customer service here y'all. It's been years since I've been here. I had my old Camry headunit done here, had my Honda Accord sound system done here. This time around, my gfs car. A used Mazda 6, that she just got, the auxiliary cord port was broken and wouldn't work. I tried to fix it myself.. to no success. I stopped by this sho and they fixed it! Saved me $$$ going to dealer and or getting the part. This shop and their customer service is dope. Sometimes business in life is earned by actions like this shop does here. Happy holidays, merry Christmas and happy new year to everyone here!! read more

Great Service from Henry and his team! Humble yet knowledgable, they know how to wire and ensure quality results. They helped me install my USB power and connect my camera recorder. Great service! read more

I got a new car stereo and speakers here about a week a go. The owner was really nice. The service was really quick, took the car in around 11 am and had it back by 1 pm. The stereo is great and it looks really good. I would recommend this place for any car stereo needs. read more

I went there the other day and got my alarm fix and the owner was really cool and fixed gratis cause I also bought tires for my car. He also gave me a great deal on my tires too, cheaper than Costco and a lot cheaper than those big chain tire stores. While I was there I found out he won a lot of awards for custom work done on cars for DUB shows, Las Vegas SEMA shows, and Low Rider shows. Check him out, ask for Solo. read more

Great place to drop by if you need any car audio system help / car alarm help. Had my stereo and speakers installed today along with the viper alarm that I bought here. Reasonably price with great services. Very recommended to anyone. read more

Better than 5 stars! This place is no joke. The owner Henry is a cool dude. I just had my back up camera installed here. Pricing and service were the best I could find. If you need any audio or camera done just come here and you won't be disappointed. Thanks again Henry! read more

Hmm, with so many positive reviews I questioned if they were just "pumped up". Well they are real. From the moment I entered the shop till the conclusion of my follow-up install the service was great. Henry patiently dealt with my numerous questions. The prices for the equipment and installation was very reasonable. Definitely recommend. read more

The best audio shop in town where you can go and not get ripped off.Highly recommended!!!

I bought a car alarm and got it installed here. He has done an excellent job. My car was having a bit of a problem though but it is because my car is OLD. They do know what they are doing and Henry did got everything done perfectly and he is very helpful. Such a great guy to do business with. I would really recommend this place. read more

This guys are the best in the business. Henry and all the staff are very knowledgeable and professional. I don't mind driving 1 hour cause it worth it!! Thank you read more

I highly recommend this place! Very honest, helpful, and amazing ownership. The sound to my car wasn't working and another place told me I had to replace both my speakers, but didn't want to spend close to $200! I drove 30 minutes to custom audio designs and turns out I didn't have to replace my speakers and all I had was a lose wire! It was definitely worth the drive and I'll definitely be going back in the future! read more

Custom Audio Designs, led by shop owner Henry and his lead associate Art, are true professionals. I booked a Saturday afternoon appointment with Henry for custom light installation and a speaker upgrade. Henry and Art quickly started working on my car, and they were excellent at both troubleshooting for issues as well as improvising for a custom fit. Their prices are excellent, their attitude is friendly, and their work results in complete satisfaction. I will definitely use them again, and I recommend others to give them a try! read more

This is a truly well deserved 5-star review. First time I ever requested quotes on Yelp and Henry was first to respond (in 8 minutes) with the best price (by far), and did an outstanding job installing a hardwired backup camera for my Ford Transit Connect. To top it off, he did the install the same day despite his busy schedule. He's very friendly and just an all around great guy to deal with. Other shops were just barely responding to my quote when Henry was already done. This is how you get business done! read more

DEFINITELY AN AUDIO STORE YOU CAN RELY ON. I just moved recently to Diamond Bar and had to install a few items into my car so I looked around for a close audio store nearby. I've been to multiple car audio shops esp. for being in the import industry in the past and Ive always had places that either: 1) did the job halfass 2) always tried to upsell you 3) just had that intimidation feeling where it didnt matter if you went with them or not... But Not This Place..customer service was top notch..Henry and Art were very friendly, straight up, and gave recommendations (not upselling). I'm glad I went here and will bring more of my business to them..its rare nowadays to find a store that gives both quality work and A+ customer service. read more

Great friendly service- fast and efficient, these guys know what they are doing. Brought my lexus in for them to install an amp and subwoofer. They handled it in an hour. Definitely hit them for any of your audio needs. Great service and good people read more

Wow, what can I say? Three times I have dealt with Henry. Three times I was treated with with courtesy, excellent service, and very fair pricing. He didn't try to sell me thing anything that wasn't necessary and was right on with estimated time and price. Great place to do business. read more

Henry and his crew took care of my car alarm. I love the service so much that I came back a few days later to upgrade my audio systems with a new audio unit and speakers. I like that they are knowledgeable about everything they do, and get the job done on time. Highly recommended! read more
