Tri Audio is your one-stop shop for all your car audio needs. Mike has helped me install systems in multiple vehicles that would have otherwise cost me a fortune elsewhere. His knowledge and over 40 years of experience in car audio installation, along with his background as an electrician, really show in the quality of his work. Whether you're looking for a simple speaker upgrade or a fully custom system, Mike can fabricate and build exactly what you want. He's also flexible and works with whatever brands you prefer. If you're looking for honest advice, quality workmanship, and someone who truly cares about getting the job done right, I highly recommend Tri Audio. I'll definitely be coming back for my future car audio projects. read more

I had him stall an Apple car play into my dash, could not get the music through my new Apple car play, to my amp. I had to take my car to another shop to find out he destroyed the audio harness!!! Pinched a bunch of wires... I had him install a trunk style back up camera, now I can't even open my trunk!!! I won't give him one star!! If you read this review which I hope you do to save yourself a lot of pain, he obviously doesn't know what he's doing he had my car for 12hrs which was suppose to be a 4 hr job. I never write reviews but I'm trying to save the next customer the headache!!! read more

Mike is the best he installed earthquake 12s in my trunk of my car and they sound amazing best in the Bay Area !

Mike is a good guy does good work has been doing car installation and beat since 1970 highly recommended

I was a regular customer of Soundwave for a long time but I was surprised to find that they went out of business. With a bad Pioneer radio that Soundwave installed 5 years ago I had to find a new place. My friend started to look around and found Tri Audio Sound and I happen to be right downt the street. I ended up with a unit that was priced right but it just didn't work very well, I told Mike that it had issues. He was completely understanding and agreed that it wasn't accepable. He ordered a new Apline unit that was way better and did an install on an agreed time/day. Mike is a great guy and I saw several other installs that he did, including a complete overhaul install on my friends 06' Porche boxster and it was clean and good. Not sure where Dave C's install went wrong but I would ignore that review since all the other ones are 5 stars including this one from an Elite Yelper read more

I was dragging my feet when it came to replacing the passenger side door speaker in my sister's Kia. While casually bringing it up in conversation with my cousin he quickly responded "Why don't you call Mike?! Everyone knows Mike!" I however, did not know Mike lol. Now I do and now I indeed know why everyone SHOULD know Mike. A true master of his craft and with all the years he's been in business he is still passionate and advancing his knowledge to hone his craft. My job was no doubt small and perceivably easy, but it was the knowledge I gained and genuine exchange I had with Mike. An overall good guy and straight shooter, he listened to my needs, laid out my options and then gave me his input where needed. He did not try to upsell me, and he gave me a beyond fair price. Had me in and out in now time. I am a huge advocate for supporting local businesses especially those that have been mainstays in the Bay Area, these businesses are a last of a dying breed and we are fortunate to have such a high quality business still around. Mike called me a day after installation to make sure I was still satisfied with the speaker. I told him it made a world of difference, now let's hope my sister doesn't blow another one lol. I recommended Tri Auto Sound, and I will be bringing some of my classic cars back for a system hook up so I can be ready for summer. read more

Mike (the owner) is trustworthy, knowledgeable, and efficient. He replaced a speaker in my Audi A4 and charged me much less than the dealer would have charged me. Bonus: when you visit his shop you get a chance to see his collection of car stereo stuff. It is like a museum! read more

Mike is the man! You know the subwoofers the dude bought at the end of Italian job. Mike's are better and way more reasonably priced. He will plug you for sure. Also we have to support our small local business owners. But don't give him too much business or else he's going to retire and you all missed out on the best sound job your car could ever get. Thanks so much for the great job and I'm sorry it took so long to post this review. I actually did not have a Yelp account at the time. Cheers bud. read more

Michael rescued my kitty cat Angus from a would-be-cat-napper and kept Angus safe in his shop, giving him food and water, until he saw my "missing cat" poster. I'm very thankful for Michael's kindness. read more

Wow, how I would love to have given a small business owner a stellar review....alas I cannot. I brought my car in for work by Mike (actually a very nice guy), I picked the place because it was solidly reviewed on yelp and was not a ton of teenagers at BestBuy. Mike did an initial install, ran into a few issues and he kindly offered to fix the issues (stereo kept shutting off). Unfortunately this meant that he had to re-run wire throughout (instead of using existing wiring). This is where his work became shotty and is obvious he was lazy. He didn't properly route the cables, which resulted in cables being cut/pinched when I used my parking brake. The wire runs between the frame and the door were not included in the protective boot, thus they get pinched when the door opens and closes. He did not put the door panels back on properly, resulting in the panels half falling off. The mess of wires behind the stereo would make a rat proud. If you want someone who is going to do nice wire management, put your car back the way you had it, and leave you with the car better than you started.....go elsewhere. read more

First let me say Mike is awesome second don't judge by looks I've been to a lot of audio shops where every thing looks wise is on point but the workers don't know squat. Mike has been a part of this industry for a long time and knows his stuff very knowledgeable knows his products and is very reasonable when it comes to pricing. I went to his shop to get some 0 gauge wire for the big 3 upgrade on my car audio system not only did I get what I came for for a good price I got to have a very long conversation about his history in the audio world one word wow good guy good conversation will be visiting him in the future. read more

I always have a great experience whenever I need anything installed, mike is super friendly and is extremely knowledgeable about the installation process and the products and always takes his time to make sure everything gets done properly. This is an excellent place for car audio needs. read more

First piece of advice I can give you about Tri-Audio is don't judge a book by it's cover. I called one afternoon and left a voice mail saying my daughters' Xterra had a Kenwood Deck with Bluetooth that just stopped working. Mike called me back the next day and gave me his cell number and said he'd take a look at it. He said to call him after 11:00 and I could bring it by one afternoon. I took the car in a couple of days later and he said he wanted to check the fuses. He gave me a fair price to troubleshoot it. There were 4 sets of fuses! One by glovebox. Two under the hood and one behind the deck in the dash. So he checked all but the one behind the dash and they were all good. He said I could wait or leave the car as it would take him about an hour to pull the console and check the last fuse. He remarked if the last fuse was good then the deck was probably bad and needed replacement but he'd work the troubleshooting fee into the price of the new deck. I left the car and pretty much resigned myself that we'd probably need to replace the deck. To my pleasant surprise when I returned he said that last fuse was bad so he replaced it and it was good to go. I was shocked! The honesty is what I appreciated the most. Another shop could have used the opportunity to sell and install a new deck. But he didn't do that. The second thing is that Mike knows his shit. He knew the electrical layout of the Xterra and he had a lot of knowledge about his new products including the speakers. I would recommend Tri-Audio to anyone replacing their audio video and especially if you have problems with your current system to troubleshoot!! He has over 30 years of experience. read more

Mike is truly one of a kind. I couldn't be more happy with the level of service he provided me and two other of my close friends. After reaching out to multiple businesses Mike had quoted me the lowest price, so naturally I had to pick him. I brought in my 2019 Avalon and he was very upfront with the expectation about working with a 2019 vehicle. That day not only Mike beat his time estimate, he also stayed later to get my car taken care of. It was perfect, not a hitch in the system or anything. He mounted them in my trunk perfectly with nothing more than 2 screws into a piece of styrofoam. The next day Mike gave me a call to ensure everything was good and there weren't any issues. I couldn't be more satisfied with Mike. Thank you very much. read more

I had an electrical problem with my Ford Focus. The dealership wanted an obscene amount of money to just diagnose the problem. Mike fixed it in less than a half hour for about 10% of what the dealer wanted to just diagnose it. And, he even bought me a soda! read more

Total garbage! Had my bf bring in my car to get hooked up and was totally disappointed with the job that was done... I came back another time to have him (MIKE) look at it AGAIN! and his psycho girlfriend was arguing with him AND SHE EVEN SAID how BAD HIS CUSTOMER SERVICE WAS! Totally wasted my money on this pathetic & mediocre so called business would NOT recommend this place to anyone! read more

Why bother going anywhere else? He is the real deal and is completely honest with his work! Have audio issues? He'll fix it. Want to upgrade your sound system and have no idea what you're doing or what to look for? He's got you covered.. and more neat features including cameras And all at a reasonable price to top it all off! If you want someone working on your car get someone with a passion for the work and that's Mike. He'll explain everything in detail because he knows his stuff. I'll be back for all my car audio needs. Thanks again Mike! read more

First and foremost I want to say thank you for the installation I really love the time and effort and care you put into my car!! I am definitely recommending you to all my friends and family, although it took a bit of time I understand why especially with these newer cars alot if wires but also everything is still functioning correctly like my bluetooth, rear camera, GPS, steering controls, everything!! Amazing talent and you've been the business for over 50 yrs I can stop saying what good work you do and at a highly reasonable price!! Thanks again Mike read more

I absolutely trust Mike! He's very personable. He's fixed my RV home more than once. He's educated in everything! He can do auto mechanic work, house work, anything! Ask him and he'll know! He runs his business like the olden days, he actually answers the phone, he does the work, and he knows what to do. Thanks Mike! read more

I was looking for a mew set of speakers for my truck. While searching on yelp, I found Mike at Tri-Audio Sound. Mike got me in right away and he knew exactly what I needed to make my truck rock! Mike recommended American made products which made me very happy. I got a new deck, 4 new speakers and an amp for an extremely reasonable price. I appreciate that Mike didn't take advantage of me and he was very fair! Mike has been working in the office industry for ver 50 years, and it shows with the detail in his work and he takes great pride in what he does. He said "my name is on this and I never let a customers without everything working properly " I highly recommend Tri-Audio sound for any music needs, both in your vehicle or your home. Mike is brilliant and is a true professional. He stands behind his work and I trust him to be there if anything goes wrong ( which I don't think it would). Thank you Mike, you will definitely be seeing me again! read more

I am originally from Chicago. My dad was the one who always took care of car issues I had. So when I moved out to the Bay Area, I felt so overwhelmed. Michael is terrific. He explained things to me that made sense. He fixed my audio problem for 3-4 times cheaper than the dealership quoted me. I can't thank him enough! I'm definitely coming back to him to get other things fixed. I highly recommend every women who isn't familiar about cars to go to him!!!! read more

This is probably the best experience I've ever had at a car shop. Mike is a genuine person who has 50+ years of experience. Even if he can't find a solution to your problem (very rare), he'll point you in the right direction. The first time I went in there he spent 30-40 minutes just answering any question I had. For me, this speaks to his customer service, and his appreciation for people. If you're looking for somebody to fix your audio issues, Mike is the guy. read more
