The Car Stereo Company

Great quality of the services provided and the owner is very responsive. Every question and concern I had they fixed on time.

Did my second car there, and will come back again.

I have upgraded the audio system in every car I have owned since I was a teenager. New (modern) cars are a different animal, of course, since you can't drop a new head unit in there and expect to get a proper feed to your speakers. So, we have to resort to line output converters or digital signal processors in order to get a good, clean feed to the aftermarket equipment we've purchased.

In my case, I have a 2017 Audi A3 with an Alpine 4-channel amp and a Down4Sound sub amp with a 12" JL Audio 12W3v3-2 sub and a JL Audio Fix86 to clean up the factory EQ and give me something to work with... I do as much of the work as possible, myself (including replacing all of the speakers, installing the amps and a relay with a switch to alleviate the amp start-up noise. I KNEW I needed some help with the tuning of the system... I set the gains using a multimeter and the input voltage numbers (to avoid blowing the amps) and just wasn't happy with the sound.

Hai was really great (as were the rest of the guys at he shop - good taste in music, too - I stayed there and worked while Hai worked on my car). I knew I needed a DSP, but Hai explained that he felt he knew what was wrong and that he could adjust the system to my liking.

Long story-short, I spent a couple of hours at the shop and Hai took some measurements and made some adjustments... I do NOT like giving poor reviews - in fact, I typically will avoid reviewing if I don't have anything nice to say. I spent over $300 and, when I got home, the first thing I had to do was turn all the gains down as everything was clipping like mad --- to the point that speakers or amps were going to be damaged. Also, due to the gains being so high, there was a ton of noise introduced into the system that Hai explained was due to the power wires being too close to the speaker cabling. Well, I took this into account when I wired it up, but went ahead and re-wired the entire system again. The wiring didn't change anything, reducing the gains quieted everything down.

Really, the worst part (aside from spending yet another night working on the car AND dropping that much cash for no reason) was that Hai told me, afterward, that he actually lowered the gains on the amps. C'mon... it's my car and my system... I knew where the gains were set.

I took my car in to get some messy wiring and wonky sound system cleaned up and replaced. Hai was very helpful with advising me on what system would work best and I eventually got a wireless android audio unit and I love it. It's installed cleanly and looks great and works perfect. They were even willing to work with me to keep the cost down. Will be going back for future work on installing an alarm.

True audio and security professionals. I found Hai and his team to be very well versed on all things audio and electronics. They hooked-up my cars with dash-cams, security systems, sound deadening insulation, corrected a prior shop's mistakes, audio equipment, interior & exterior lighting. Been to many different shops in the South Bay, none more reliable than the Car Stereo Company.

I had a nagging audio issue in my 2019 Subaru Crosstrek that I couldn't figure out. Dealership recommended buying a new amp; I bought a new one myself, and it didn't fix the problem. Brought my car here and in less than two hours, Hai figured out the problem, replaced the necessary parts, and charged me a fair rate.

$240 for diagnostic, parts (2 tweeters, wiring), and labor was very fair given that the dealership wanted $1200 for parts/labor for something that wouldn't have fixed the problem in the first place. I'll be back here next time I have any kind of audio issue (or even electronics issues) with my car, because they actually try diagnosing the issue instead of throwing things at the wall and seeing what sticks.

Excellent customer service from the owner to Melissa in the office
they installed a Viper car alarm and a stereo/navigation system. You don't just want an installer, you also get the support from this company. Their price was also very competitive.

Got a couple different quotes from car audio shops for my car but the problem is, I'm SUPER PICKY with where I take my car to. (Yes, I am the PITA customer when it comes to my car. No shame)
I reached out to Melissa a couple times for quotes to install a subwoofer and amp + bass knob and arranged for a date for me to bring my car in the shop. Their quote was very reasonably priced and they had no problems with me bringing my own parts as well. Unfortunately, I had a tragic family incident so I couldn't make it to my original install date.
Melissa was very accommodating and rescheduled my install date for their next availability that worked with my schedule
After getting my car back, I thought I had noticed something on my car was scratched, so I texted them. Hai reached out within 15 minutes after my message. He had the replacement part ordered the next day.
Fast forward to when I come in, he takes off the part, and cleans it... no scratch at all. It was just dirty. ‍
Customer service 10 stars Hai immediately accepted responsibility, addressed it, and worked out a solution in less than 30min, for a problem that ended up not being an issue. Can't ask for more better honest business practices.
How the subwoofer, bass knob, and amp sounds (full JL Audio setup installed) 5 stars
Don't hesitate to reach out to Melissa or Hai for any aftermarket car audio/electrical needs, they will take care of you. I wish more auto shops and auto related businesses were as prompt as they were and actually take care of their customers. This is coming from someone who's been in the auto industry since high school, I appreciate it because I've seen it all.
Will definitely be a repeat customer if I decide to add a dash cam and some sound deadening to the trunk!

Great place, definitely recommend!

The staff there, especially Hai, were very professional and helpful. They helped me choose the right components and design for a car audio upgrade, and even though I had a lot of questions they were very patient and thorough.

I really appreciated how they explained the things they do that make an aftermarket stereo install done right, like checking with manufacturers (car and audio), and getting door pinouts to avoid unnecessary modifications or any type of change that would prevent future service like to fix a door window or lock problem.

They also have a good selection of quality brands - Focal, Helix, and mObridge to name a few.

A little hard to see driving by because their building is fairly plain looking on the front without a huge sign, but GPS should get you there.

Service professionally explained, quoted, scheduled and completed exactly as promised. Friendly and reliable shop.

Hai is great, took time out of his day to give me information and advice on speakers and setup, as well as confirming my suspicions of a blown speaker. Very professional and he knows his stuff, highly recommend this place for anything car audio related.
