For context I had an existing setup of a pre-wired box w/ two 12" kickers & a 1000W amp that had a severely blown fuse w/ a burnt out cable due to the nature of my original install / running the system too hot in my 2020 Corolla. Ernesto is the owner and main technician and his assistant Fernando helps out with the jobs, communications and billing portion. They take cash or card via Square w/ a 4% card fee. Within 90 minutes these guys were able to do the following; remove the blown fuse, remove the burnt cable, install a new fuse, install a new cable (w/ some PVC corrugated covering), cable manage, improve my cable pathing, improve my electric ground for the circuit, and EQ or "tune" my setup and have it back better than ever. The cost was great also, a flat $160 for all of the above! Would recommend read more

MG Car Audio Electronics - Before - Car Stereo Installation Near Me - Santa Rosa, California

See all

Add me to the list of impressed, happy and satisfied customers of this business! Ernesto hardwired front and back dashcams in my mini SUV. I know it is a difficult job, because my usual, knowledgeable mechanic refused to attempt it. I understand it's not the hardwiring itself, it is carefully and skillfully threading the wires from the front camera through the side of the car without setting off the curtain air bags along the way. Ernesto accomplished this, and a job that could easily have taken four hours was finished much sooner than I expected. Not only that, but Ernesto is a highly likeable guy and treats his customers well. I was very, very impressed with him and his small business, and wish him continued success. read more

I had been wanted by my Durango to sound like my Chrysler so I started researching audio companies. Being a woman I was prepared to be met with exaggerated pricing and attempted upselling of things I didn't need. Of the three locations I went to, MG Car Audio were the only ones to treat me equally and not upsell me. I pulled up without an appointment and Ernesto was happy to take a look at my Durango, listen to me try to describe what I was looking for and took measurements for box size. Fernando was my point of contact for questions, and I have a lot, and he responded quickly and if he didn't know, he would reach out to Ernesto to get the answer. These guys treat you like family, very respectable business ethic, and I like that when you choose Ernesto and Fernando, you're choosing community over corporation. In fact, I will be going back to have some additional work done. read more

This place is the best kept secret of Santa Rosa. If you have any issues with stereo, or electronics, make an appointment here and thank me later. Ernesto and his team was very efficient and knowledgeable. They were able to diagnose promptly where the electrical problem was on our motorcycle even when mechanics were struggling. He went above and beyond to explain possible causes, and recommended solutions too! Dependeble, reliable and responds in a timely manner. Highly recommend!! read more

MG Car Audio Electronics - Car Stereo Installation Near Me - Santa Rosa, California

This guy is the best in town. Took my motorhome for a new stereo half the buttons on my steering wheel did not work. He fixed everything had to modify the kit. Just outstanding work. I would and will do business whether him again. Thank you again. read more

Ernesto and Fernando were awesome. They helped complete an install of my Pioneer radio and were able to hook up all the control to the steering wheel and backup camera. They were polite and respectful and I will tell everyone to come to them for their car stereo needs. read more

So awesome to meet a man with honesty, integrity and kindness. I ran into problems trying to install a car stereo and came to Ernesto for help. He diagnosed the problem and suggested how I could fix it on my own. I would have gladly paid him, but he didn't even charge me for the help and information. What a great experience. read more

I had a 2013 Toyota Camry with a backup camera that was getting foggy. The guys at MG Car Audio diagnosed the problem (it had vapor inside the camera body) and replaced it within an hour, all for the low price of $60. If I need car audio or backup camera repair, these will be the guys I come back to! read more

I'm elated with my new car audio system & backup camera and equally elated with interactions with this lovely owner-operated business. Ernesto provided top notch service with high integrity. He sold to me only what was needed, although I had expected to have to purchase more components. He and his right hand man Fernando spent a lot of time on my job - it wasn't super straightforward - then afterwards even offered the time for a tutorial and to set up the acoustics to my liking. Good people. Highly recommended. read more

Bought a 2015 Dodge Ram 1500 a few months ago. Radio not working. Works great now; Digital Clock as well. Fernando had the whole dash apart and back together within 30 minutes. Great mechanic. Really knows his stuff. read more

Have you ever made a happy mistake? That's how I found MG Car Audio...by a very happy mistake. I thought this was this other business I had driven by a bajillion times, and was quite surprised when Google navigated me to the rear of a partially chained empty parking lot. But there it was, MG Audio. My appointment was for noon, and by 5pm on that same day MG Car Audio had installed what I can only describe as absolute insanity in my 2017 Ford Focus. Honestly, I drove home that day with hilarious bass. You ever heard bass so ridiculous it made you giggle? THAT bass. Bass so deep it shifts your organs. I'm pretty sure that bass was trying to kill me. All I'm sayin' is when I turned the stereo off it felt like I was coming out of warp. My mind was absolutely empty and I rumor has it that I may have even peed myself...just a little. Sub woofer and amp wired to factory stereo controls, so no extra wires or knobs or buttons glued to the console or sticking out from under the seat. Only pure madness in the trunk, just the way I like it. And what happened when I punctured my Rockford and showed up with a brand new Kicker? Fernando swapped it out in 10 minutes and told me to have a nice day. Actually, what he said was "It's all good. We're here to help." Mission accomplished! I'm a customer for life. I can't wait to see what these guys can do with the other 200 watts my amp isn't using. Thank you MG Car Audio. read more

Their communication is super great. Very fair and never tried to upsell me. I would highly recommend for anyone that wants an installation.

Ernesto is fast, honest and an excellent troubleshooter when it comes to audio technology issues. In my opinion for the work he put in, he under priced his services. I will definitely use him again and will certainly refer him to anyone that I hear has a stereo problem. What a pleasure it was dealing with him. Bill Snell read more

my long overdue review of Ernesto and MG Car Audio. I have a couple of rare low production vehicles which when i used to live in the Bay Area, had work done , at what were supposed to be the last few great car stereo shops. That also meant very pricey as well. I found Ernesto off Yelp and gave him a shot. so far he has worked on two of my cars and simply does outstanding work. He cleaned up the mess of wiring which the prior shops did this past weekend and got rid of all extraneous noise in the system. he has also had to repair some things on the fly which other shops would probably not be able to figure out or handle. He repaired these at no extra charge. i really can't think of a better place to have car stereo work done on than MG. Priced fairly, done cleanly . I should note, he really doesn't stock or sell much stuff. You basically just figure out what you want and buy it and bring it over. my only gripe, and important to know is, getting a hold of him to talk or set an appointment is tough. It is one of those deals, where you have to swing by, show him what you need done. If he is free, he usually does it on the spot, but there are times you need to set a future appointment in person. read more

I came in with a broken subwoofer. I was very worried I'd have to pay a large fee to fix whatever had blown. I met my guy Ernesto who replaced the small fuse in my sub and had it working in 5 minutes. Ernesto was very friendly and didn't even charge me for the simple fix. This is by far the best service I have had after being to numerous car audio places in the area. read more

Do not go anywhere else but here!! I highly recommend Ernesto Guzman at 1580 Sebastopol Rd. (not the place with the same name). Ernesto is the most professional, kind, reliable person. He is the owner of MG CarAudio and takes pride in his company and in his work. His prices are very reasonable and his work is stellar. He installed an auxiliary unit in my 2004 Prius. He completed the job in the time he quoted me. Wish everyone cared as much about customer service and professionalism as Ernesto! If you look at his Yelp reviews you clearly see this is the place to go for stereo installation and car audio needs. Thanks Ernesto!! read more

I had Ernesto and his staff re-do our Jeep's sound system because the stock equipment was pretty worn out. He suggested speakers and a deck that were well within my price range, after looking over a few options I chose the ones that seemed ideal, and they installed them quickly and cleanly. I was honestly a little intimidated to do a whole car sound system overhaul, but they made it simple and charged a really reasonable installation rate. We've had our Jeep with it's new system for quite some time now and it still works perfectly, I recommend these guys if you want an efficient and well done job without having to deal with Best Buy or the craziness of Santa Rosa Ave. read more

Ernesto's a good guy. I worked with him when they were MG Audio and I trust him for the repairs of my stereo equipment and car audio installations. read more

Ernesto installed a doudle-din, Apple Car Play, touch screen unit and backup camera in my 2004 Solara. Amazing installation...looks just like a factory install. No visible wires or pieces that don't fit. Works flawlessly and makes my OEM speakers sound 100% better. I highly recommend them. Ernesto knows his way around auto electronics. read more

These guys were awesome. They gave me a cheap quote to replace a stereo deck and because it was me who put it in originally, I cut all the wires which they didn't know about. This took them more time yet they still charged me what they quoted me originally. While they were working, they pointed out other things that I had setup wrong and looked online to find me the right equipment for the cheapest instead of just trying to up the price and sell me it themselves. They also explained how to properly set it all up so that I can do it myself again. They saved me some money too. Because I didn't have a stupid little adapter for radio, they rigged up one themselves and did it in a way that looks like it'll last. So now I have radio and the knowledge of the right equipment for my stereo system to avoid having my stereo deck blow again. read more

I found them on Yelp, and wanted to give my daughter a rear-view camera for her Christmas present. Fernando and Ernesto did an amazing job. My daughter was so surprised! I highly recommend MG Audio and will definitely come back. read more

The CD player on my Lexus (Mark Levinson) broke. I took it to MG Car audio. Ernesto was able to disassemble the head unit and repair the player while I waited. Couldn't be happier with the quality of the work. Would definitely recommend this shop to family and friends. read more

Ernesto was awesome. Excellent customer service. I will refer as many people as I can to this store because of the excellent service and money I saved. He fixed my problem, even though it had nothing to do with my car audio system. It was a rattling noise coming from up under the hood of my truck. He was able to locate the source of the rattle and muffle the sound using his amazing skill set and customer service. I will definitely be back. read more

These guys just successfully installed a sound system and aftermarket head unit into my 2019 sprinter van. It was a notoriously challenging projecct due to the lack of information on the vehicle. Although I did not have the parts to complete the project, they were able to scavenge them from a local van converter and get it working all in a few hours. I've never heard such good audio in a van. Highly recommend MG audio. read more

Honest straightforward and very competent. Ernesto and Fernando took great care of us.

Ernesto and Fernando were kind and got the my work done on 2 cars here for audio installation and removal. Excellent service at the great price. After a few short hours everything came out perfect! Well worth it! Will be coming back when it's time for a subwoofer! read more

Called the shop on Saturday, was advised to bring my car in first thing Monday. After checking with a few of his competitors I arrived around noon. Ernesto got right to work and within 30 mins my car had a new stereo! Very happy with his work, nice guy too. read more

Ernesto is great. I couldn't figure out my old wiring harness because the colors on the wires didnt match the original wiring diagram. Ernesto just looked at me and asked if I was ready and then bing, bang and boom!... Stereo works and sounds great! This guy knows what he is doing. read more

Great expedient service! I was very pleased with their installation and surprised how fast they were able to start working on my car (pretty much immediately). The guys were very professional and friendly and i would definitely recommend to friends and family. read more

Ernesto was great. We got our car stereo installed in less than an hour. Highly recommend.

Fast, friendly service. Ernesto installed a Pioneer DEH-X3700UI for a great price and had the job done in about half an hour. He also took the time to set the clock and show me how to program the radio and use it's various features. The new radio sounds much better than my old one and also charges and plays music from my iPhone, and the USB port plays music from a thumb drive. I'm pleased with the radio so far both for the sound quality and ease of use. Good experience. read more

I had the Pioneer appradio4 installed. From the first phone call a few days ago through installation today, these guys were complete professionals. It would be hard be beat their customer service or installation skills. I will definitely return for new speakers and an amp. read more

Fernando and Ernesto did a fantastic job installing a Kenwood double-din, rear-view camera, speakers and mic in my Outback. I bought all the gear through Crutchfield, and they installed it perfectly. (I actually don't think they sell systems.) Their install prices are reasonable, and work totally pro. Will absolutely return and recommend them highly. read more

This review is for Ernesto the owner of MG Car Audio, not his old employee who ran off with a copy cat name & works out of his home. Ernesto has a real shop with actual work hours & is attentive & does excellent work. I actually had contacted the other MG but they can only work on your car after 4pm & being in someone's house did not instill confidence. Ernesto is very reasonably PRICED & you get a workmanship guarantee. I will use Ernesto again to do the sound system on my other truck. read more

Ernesto is very very good at what he does. I had him replace my factory radio with a new unit that give me bluetooth / navigation and also he added a steering wheel adapter to keep it still working from my steering wheel. Although the wiring didn't match up for the adapter he stuck with it and had it all working by the time he was finished putting everything back in place. If you need audio work done, this is the place to go. His prices are far better than anything on Santa Rosa Ave. read more

On 1/13/2016 I had my 2 subwoofers, an amplifier, and a line-out-converter (because i kept the stock deck) installed. He was very thorough explaining what he was going to do and asked how I want it done. I can tell he has alot of experience and takes pride in doing quality work. I felt at ease leaving my car with him. With competitive pricing too, I would recommend this place to anyone. PS there is no lounge/seating here so have a your waiting planned to be elsewhere. read more

Best car audio place in Sonoma county with great work. Recently Ernesto completely redid my sound system in my 2010 g37 installing new speakers an amp to run them and a subwoofer and it sounds great. Go to him for all your car audio needs don't go to the Santa Rosa avenue rip offs that overcharge you for their equipment (tried charging me $200 for speakers that cost $75) and charge you a ton for installation. Thanks again Ernesto! read more

These guys were great! They knew exactly what they were doing when every other place I called was either booked, or didn't know what they were doing. They showed up on short notice, and gave some of the best customer service i've seen around here in awhile! 100% recommended! read more

This place is terrific. I needed a new stereo/dvd/backup camera and they did a wonderful job advising me on selection and going the extra mile with installing. Ernesto and Fernando are great at what they do, and nice people to boot. I recommend them highly. read more

These guys are amazing. They work fast and hard to get the problem fixed and did a great job getting my phone to connect to my Bluetooth as it would read as connected but would not play on my stereo. After about ten minutes of working on it they figured it out and got my Bluetooth to connect and play through my speakers. I will be coming back if I have and electrical or car audio needs as they did an excellent job. I would recommend going there before any other shop in the area! read more
