I feel the need to share my experience with fellow Yelpers about this wonderfully run car audio shop. A few years ago, I made the mistake of purchasing a Cadillac Deville and my first instinct was to install a Audio/Video system. I came across GM Electronic's ad in a weekly East Bay paper and like many others, I was attracted by their low prices. I made a phone call and followed up with their advertised special and sure enough, I made my way to Concord. I purchased a 15" drop down and a DVD player for about $500 including installation. My installation was scheduled and I was promised the work to be completed within a few hours. Instead of heading home, I went down the street and watched two movies at the theater. With two movies watched and still no phone call, I made my way back to the shop. As I approached the shop, the doors were closed and the lights were off, but my car was outside. I luckily came across a person locking the front door and asked about my car and what was going on. He replied that the job was done and I asked why I wasn't called and he did not have an answer. Had I not ran into the employee, I would of been stuck in Concord with no means of getting back to the East Bay. Nevertheless, it was dark and the shop was closed, and I was given my keys and work order. I headed home and played with my new drop down and powered on the screen and the DVD player. Surprisingly, the DVD player powered on but I was unable to insert a disc. Upon closer examination, the DVD player had a DVD/CD jammed inside. I disconnected the player and noticed it was scuffed and scratched. I couldn't believe they installed such garbage and didn't care to test their installation. I headed back the next day and was given another DVD player, a new one, I assume, but lost me as a returning customer. I would strongly suggest any potential customers to stay away from GM, as their products are cheap and potentially used. GM Electronic's is essentially a brick and mortar version of Craigslist. read more

GM Electronics - GM Electronics Store Front - Car Stereo Installation Near Me - Concord, California

So I had my whole ass stereo system put in her about a year ago. I LOST THE RECEIPT as most of us do so no warranty. I expected that as it makes perfect scenes. So Rachell informed me of the diagnostic fee (which I agreed to) and had a tech take a look. FUCK! I needed a new AMP. Ok not in budget! HOWEVER Rachell worked it to get me the best quality for the right price. So with the diagnostic fee and the new AMP... I spent $$ I wasn't expecting to but I can't go another week with out SLAP! All in all I'm very happy with Rachell and her customer service! Not to mention she gave me a little tip... TAKE A PICTURE OF YOUR RECEIPTS!!!!! Your less likely to loose your phone and a piece of paper. read more

Caveat empto! Caveat empto! Caveat empto! Caveat empto! Still at 1 star bc that's all I can give. So Friday March 9th, I discovered a new discovery. I ride solo bolo ALL THE TIME and this particular time me my my bruh was riding to the store. I stayed in while he bounced out (passenger side door). No biggie. Then my song came on, I'm like let me turn it up. Well when I did, I noticed the hi's was high and only the speakers in the front was on. I'm like oh, let me turn the bass up (thinking I turned it down subconsciously). That's when I noticed it didn't work along with the 6x9's in the back! I'm like what the heck! So I started the car then BOMB! bass back on, along with the hi's, the speakers in the front and the 6x9's in the back, but I noticed the hi's are low, like muted some the way they fixed it to be. (Still think that filter or whatever they did set my hi's only to go so high, follow me?) Then I turned the car off. Everything was still working all in sync. Bruh comes out the store opens the passenger door and the whole back of the system shuts off, and only the hi's and speakers in the front are playing. I'm like...........did they rig my music to work so I would STOP GOING UP THERE AND CALLING? To make sure I wasn't tripping I told my brother about it and we tested it out. He's like this don't supposed to do this. What if you wanna bump you're music with the door open? Now I'm mad all over again. I was just starting to get over it. Saturday evening I called the store and spoke with the manager who remembers me oh so well. I told him everything and he's like can you bring it down so I can look at it myself? I'm like you did the last two times -_- as nice as he was and as concerned as he appeared to be, I'm still waiting for him to return my call to either set me up with A. a courtesy car or B. a refund. I expressed my tiredness of this, and I also expressed that I understand there will be minor issues, but THIS is unacceptable! And I still wait............. Now would I be wrong if I hit them with a small claims suit? Now I'm really starting to feel like they thought they could do anything to make it work just to get rid of me. I don't even turn the mess on anymore. The joy I was hoping for via my music, sitting fours hours a day in this car is gone! I'm on the verge of going to another shop and have them redo everything verse me keep going back here, where there's obviously issues with the equipment AND the installers. read more

Ughh, I can't. Took me about 3 weeks to get my windows tinted AFTER it took me about a week to get through to someone to make an appointment. My first try making an appointment: really rude guy answered the phone, asked for my name and what type of truck I have. I let him know, he responds with the complete wrong information i JUST told him. Proceeds to ask for the make and model of my car only saying "we don't need your name it doesn't matter, you're booked" then hangs up on me, cool guy right? Customer service on point, right? So I guess my appointment was scheduled? A week later I show up, on time, to drop my truck off. "oh the tint guys isn't in today and we don't even have anyone on the schedule?" wtf.....OK. So reschedule for THREE WEEKS in advance 8am. THESE FOOLS DON'T EVEN OPEN UNTIL 10AM! I found that out when I showed up for my appointment. What the actual f... I come BACK to drop the truck off at 10am. They let me know it would be ready in two hours. It's 2:30pm and I have yet to hear from anyone. I finally reach out "ya the truck is ready" hung up on, again. I arrive to pick up my truck, looks fine. I go in to get my keys. LITERALLY as I'm leaving, like my foot is out the damn door, "oh ya don't get your windows wet and don't roll em down". At that point I just walked the F out. Customer service is fuc*ing key for business. I won't use these guys anymore and nor will I recommend that anyone go to see them. I'll try Best Guys for my brother and sister's vehicle. PEACE OUT GMLAME ELECTRONICS. read more

The best experience ever for a car stereo install/purchase! I went in on a Saturday and was helped by a young man who was mello, patient and calm. No hard sales, just helpful. I asked about my car. He looked it up and showed me an install kit that was needed. Normally, this is where most places get you on kits and wiring and installs. $35.00 plus free install on the deck! I looked up just the deck on Amazon which showed top ratings but was only $40.00 more and that was just for the stereo! So they really only charged $40.00 for all the labor and taxes! Awesome! Went in to get it installed and the owner was more than helpful and pleasant! They got it all done in less than 30 minutes! Looks awesome, sounds incredible and the price was hard to believe as it was way lower than I expected! 100% happy and would recommend this place to everyone! read more

They had what I needed for my slap!! I like that!! They also had hella selection of slapppp!! They even "Tint" by appointment! The owner was cool! Told him I was new to the neighborhood and needed a new beat shop to go to! He told me this was the spot Give them a visit!! read more

Went to GM ELECTRONICS to upgrade my Prius original sound system, and I was ripped of $1,624.00 for 4 speakers, 2 tweeters, 1 amp, 1 sub and installation, went back a week later because the whole system sounded very @#&*@$£ to say the least, the owner tried to make all kinds of adjustments, lower the bass from the sub, moved the sound from the back to the front, blamed spotify and pandora of having poor quality of down loads and blablablabla. Made an appointment to try to have the problem solved, the guy is on the roof trying to fix something and told me it would take 1 hour before he could talk to me, I said no problem I'll wait as long as I leave satisfied. (Big mistake). He responded "I am not going to put up with your shit in the morning. So I left. And i still have a expensive (i am poor) @#$%&£ sound system. But i see justice in the horizon oh yes i do. read more

This place is amazing!!!! Rachel Was so helpful. I will certainly be back. I had to bring my cousins car in for something and they were so good and well priced.

I got an appointment for window tints the day after I called. It took a couple of hours and the result is flawless. And they were cheaper than everywhere else I called, by a lot. It doesn't get any better than that! read more

I live 40 minutes away and can literally go to any tire shop in my city. But I always make an effort to come to GM because they are fair and I don't feel like the price for me is different (because I am female). Everyone there is always polite, respectful and they do what they can to accommodate my schedule (and budget!). I know you don't get a fancy waiting room and it's not the most modern facility. But that's not what makes a tire business a good place to visit. Anyway, give them a chance. They all work hard for their business. read more

Love these guys! No matter what I need they always treat me like a lady or even a little sister - they don't cheat the girls, they keep it straight up! I just had my rim inserts put back on today (they keep breaking because they are plastic going on chrome - nothing you can really do about it- just the way they're made). They hooked me up quick and easy and were fun to talk to! I had my windows tinted here too about a year ago, and they service was awesome as usual! And I love my tint job... read more

Absolutely the worst experience I've ever had. I came to this shop because my daughter told me about it it was the biggest mistake I could've made. I stopped by two weeks ago and spoke with a guy and told him what I wanted he told me that I would need a 5 channel Amp and said he had Memphis brand along with possibly changing speakers ( I had kicker speakers already ) he quoted me $800.00 I said ok and that I would be back in a week. I went back 5/4/19 and was told to come back 5/5/19 I came to the shop at 10 am spoke with nashir the manager told ( tried to tell him he didn't listen ) him what the other guy and I had spoke about and that I wanted the Memphis 5 channel Amp and the interface device for my car installed he quoted me $600.00. I ENDED UP PAYING $1000.00 he came to the waiting room and told me I needed to replace my dash and front door speakers which would $250.00 ( same two sets of speakers $170.00 online ) after sitting there from 10am to 3pm my car was done. I pay my tab and head home get down the block and the music kept going in and out I go back to the shop they investigate and found that the wires were crossed in the front door and dash speakers ( humm maybe I didn't need to replace my kicker speakers after all they never checked that he just sold me speakers I didn't need ) that didn't resolve the issue so I called for a ride and left the car while looking at the install I noticed the name on the Amp wasn't Memphis but instead Sonida Mask. The next morning I called and spoke with nashir and told him about the mix up that the Amp isn't the Amp I wanted he told me the Memphis Amp was more expensive like $500.00 I told him that I agree and that's what I thought the $600.00 quote was for that Amp and Harness. he said that he would have to charge me more for that amp. At that point this guy had my money and as you know once you pay someone cash they would do anything not to give you any back. With that said I picked my car up the next day and found out that the issue with the music going in and out was because the wires were crossed I said to him " that might've been the problem with the other speaker " lol this guy says "!your right " BUT DID HE DO THE HONEST THING and say let's put the old ones back and refund me my $ 250.00 minus labor for the dash and door speakers HE said I needed!! No HE DIDN'T. Smdh my music sounds good right now but I continue to have this feeling that I've been Robbed I'm 58 yrs old, trust and believe if I was 28, or 38 I wouldn't be writing a yep review there would definitely be trouble and a different outcome. but because I'm older I called him explained my concerns he wanted to argue and I'm not into arguing I will just end this with buyer beware this shop is a rip off. DONT USE THIS SHOP!!! Total hustle and a rip off. Of course I have nothing else to do but go around spending money with you are dealership looking to scam them. When Bashir found that the speakers were crossed after ad day the proper thing would be to refund the money I left this shop not pleased but realizing that when you deal with business like this your only recourse is the business being honest. I've made one other yelp review and unfortunately had to obtain an attorney and sue which I won I don't go around spending my money with the intent of writing yelp reviews and suing people if I was a happy customer I definitely wouldn't be spending my time on yelp. Dishonest, argument I've, and his respond is an example of that. read more

GM did a great job on the tint for my new work van! Was in and out in about an hour. From speaking to an associate on Saturday and setting up an appointment for Sunday the entire experience was exceptional. The owner was also there and I was able to discuss some future options for a back up camera. Their powered up live displays of head units allowed me to physically see the options they offer. I'll definitely be back when I'm ready to do some more electronic upgrades to my vehicles. read more

I'm very careful who I let work on my car. I have trusted their team to get the job done without any worry or problems. I recently got my window tint done here. They removed my old tint and put on much better quality tint on my new coupe. Honest working people who no wonder have been thriving off repeat customers. One of the only shops I know that do custom work at a fair price. They always seem to recommend something that fits well for my car instead of treating me like just another customer. I appreciate that type of business and will return again and again read more

This merchant charges a lot for the type of work perform. Their electronics and equipment are the cheapest intimations on brands and their technicians must be beginner techs or-apprentices as their work perform in my car cause burn fuses, power shortage, burn wires, carpet and panel. As they left peel wires and burn the inside. Also be careful, the owner never doesn't fix his errors and avoids all types of responsibilities in damages cause to your car after they work on it. They charge full price of a quality tech but they provide cheap parts and you end up paying 100 for a 12 dollar remote on alarm. The alarm is also the worse ones. They placed a 40 dollars alarm on my car and charge 459 for it. read more

Got subs and speakers installed here definitely recommend this place for all your speaker and sound system needs

Best place ever! I will recommend this place to anyone looking for superior products and excellent customer service. Jairus is one of the most knowledgeable and helpful customer service rep there. He's helpful and knows his business. It's a good feeling to go into a place to have your electronics needs met by ppl who actually know what they're doing, and wont upcharge for everything. At GM they actually love what they do and it shows in there attitude and work performance. Thank you for a wonderful, satisfying experience. read more

So thankful this business is still thriving after so many years. Needed my stereo fixed and was helped right away! In and out in no time at all. Thank you guys read more

They don't do the job right. They half ass everything and then when you take your car back to get it fixed, they never get to it. Also when your car is ready, they say they will call you and you have to call them because they never call you. Then they'll say "Yeah your car's been ready for a while now." If I could I would give them 0 stars. Worst place ever! read more

Job was done as quoted. Owner was great to talk to. Install was okay, there was loose ends but no big deal. By far the best deal in the area for a Din Bluetooth Player read more

Bad service and I felt nickel and dimed. These guys gave me a price then after making me wait hours longer than it was supposed to be, Bernie calls me up and tells me the little front side windows( those triangles) are going to be 50 dollars more! Big surprise because we had already had the estimate done before I left the car in their hands and as far as I understood those windows were included. I mean why would they not be? I get there eventually to pick up the car and see this ridiculous note on my invoice.. See attached. This is kinda stupid business practice because I had told them I was going to bring my CRV in as well. And get a stereo and speakers installed. Needless to say I found other shops to do this- Car stereo guyz for stereo ( they come to your house) , and East Bay Auto Spa for tints and had a better experience, and apparently the screens will last longer based on the warranties ( two years at GM for their American standard product versus lifetime for East Bay's. ) read more

GM Electronics - Car Stereo Installation Near Me - Concord, California

BEWARE! We brought our car here to have a new deck installed about a month ago. Today, we learned that our recent ignition problems were caused by their car stereo installation. DO NOT bring your car here for stereo installs. The backstory: About 2 weeks after the radio was installed the key became stuck in the ignition. Our goto repair shop advised to have it looked at by a locksmith because it may just be a problem with the ignition cylinder. The locksmith came by and took out the ignition cylinder, he said there was nothing wrong with the cylinder and that it was a problem in the ignition safety switch. Down $50 and still no fix we decided to have the car diagnosed by our goto repair shop. Long story short our technician found the power cable for the stereo running over to and wrapped around one of the teeth on the BCM (Body Control Module) fuse. He hooked up a scanner to the computer and was getting absolutely no response from the BCM. He believes that the stereo being hooked up to the BCM caused the BCM to short out and fail. BCM controls the ignition and thus my safety switch isn't working. Interesting factoid, A BCM repair can ONLY be done at a dealership. We went down to the Concord Chevy dealership and got a rough quote of just under $500 for a new BCM + labor. When we explained the whole problem to the Chevy Service manager said he has seen several cars come through their service center with similar problems with after market stereos installed by GM Electronics. He mentioned GM Electronics by name before we even told him that our stereo was installed there.... When we confront the owner of GM Electronics about this and asked them to cover to the cost of repairs we were informed they are not liable for the problem. So now we are left with legal action or to just eat the cost of the repairs. Again, STRONGLY advise you look elsewhere when considering a stereo installation. read more

I had a stereo installed and the quality of their work SUCKS!! They had to cut the dashboard to fit the new stereo and the opening they made was too big!!
