I asked Bill about installing underseat woofers and a Kickern 10" square powered subwoofer in my 2022 BMW M440i Coupe. He provided a quote on the sub. I already had the under seat woofers. He also told me what he'd charge to install them in my car and connect to.my new Alpha One amplifier that's made specifically for BMW. I agreed to the price and scheduled the install at his home in Rosevillebl that is just North of the Galleria Mall. I'm VERY pleased with his completed work. I recommend Bill. You will not be disappointed. read more

great place to do business with as all check points were spot on!!! Reliable, dependable, reasonable n excellent customer service! Thank you read more

Doesn't reply to texts or phone calls. Totally forgot about me and I had to remind him that he did not install my stereo. Got me in right before he closed his shop. Unit has been glitching for a while. Don't know if it was bad installation or a defective unit. read more

A heads up: The physical location is closed, as of the end of July. Bill told me he will still service vehicles by appointment only, and can be reached at the phone number shown here. TL;DR: I wish this could be a 5* review, as I think Bill is a very honest, competent, and experienced technician. Unfortunately, my recent experience was not good. In early July, I went to Folsom Car Stereo to see if Bill could fix or replace our car alarm. We knew it was a mess (installed decades ago by someone who clearly didn't have a lot of experience). Bill spent time to look at the system & wiring, and determined it was hopeless for a repair. We applied the diagnostic cost to a new system, and he replaced the wiring & system at the end of the month. He let us know of his plan to not renew the store lease coming due at the end of the month. He was semi-retiring, starting a new job, but will continue the car stereo/alarm work at his workshop by appointment only. So, we would be able to address any issues with the new alarm system if necessary. The install went well, and Bill ended up charging less than his original estimate. When I got home, my husband wanted to hear the siren. So we armed the alarm, and opened the door (the windows were down). The alarm did not go off. Nothing we did set off the alarm. There was a lengthy time interval between the end of July and when Bill was able to work on our car again, due to a family tragedy that Bill suffered. But he made good on his promise towards the end of September. Rather than fix the unit he installed, he replaced it with another, more powerful unit, at no additional cost. This new unit worked much better, and everything seemed great. Soon after I got home we started hearing the alarm randomly arming and disarming itself, multiple times an hour. Our first thought was that this will render the alarm system worthless as it would randomly disarm and unlock the door while unattended. We then figured out that this happened in our garage for the most time (we recorded the sound when we left the car unattended at other locations, and it only happened twice at one location, a huge parking lot full of cars). We were concerned that the door locking / unlocking scores of times daily would break the door locking mechanism, not to mention that we were annoyed by the constant chirping noise day and night. We tried to identify the cause by disabling all possible RF devices we could, and determining the RF frequencies of those we couldn't (e.g., SMUD's meter). We couldn't figure out any clear cause, so we contacted Bill via voice mails and emails. We hoped that he could diagnose if the unit's wiring or the device itself might be the cause, and fix the issue. We left numerous messages but he never responded to this day. Towards the end of October, we took the car to another place, and paid for a troubleshooting session. He fixed a few things (the valet switch wasn't working due to a loose wire, and the shock sensor was set too high). But he could not fix this problem, mainly because the issue occurs at our garage only. In the end, we had the new technician replace the alarm with a new model. So the money we paid to Bill was completely wasted. read more

I reached out for a quote to a few car Audio businesses in my area - folsom car stereo promptly responded, not with a quote, but with a reply saying they've chosen not to work on my model / year vehicle. I know from doing my own research just how difficult installs can be in my vehicle so I absolutely respected their position. They also took the time to make sure I was informed of the challenges so that I can address them with whomever does the work. Very much appreciated Thanks FCS - read more

While he no longer has a storefront, he still does stereo work and installed my dash cam for me. He really knows what he is doing, does good work and we found the price to be reasonable. We use him for all car device needs. read more

This place is awesome. He works from his garage at his home and focuses on one project at a time. Bill is the owner and this installer not only delivered on time to get my Apple car play and vehicle line sensors installed, but also sent me photos via text to show me the progress. I am recommending his services to my Police Agency, because of the quality of work he provides. Many thanks Bill and I have other vehicles I will be sending to you shortly!!! read more

10/10. Bill did fantastic work on my whip. Installed a JBL BassPro hub in my spare tire on my rolla HB. He knows his stuff. Walked us through the process before the install. He gave me a very fair price for top tier work. He is very knowledgeable and an honest, personable guy. You can tell that he takes price in his work. The job was very well done and left my car neat and spotless. Very neat job. Very good on communication. Quick to respond, and was more than helpful at answering any questions I had. I HIGHLY RECOMMEND, def would do business with him again in the near future! read more

They installed a rearview mirror system, Brandmotion FVMR-1100 FullVUE® replacement mirror/monitor with front- and rear-view cameras. The price was right, the product works as advertised, and the owner did an exellent install for me. I had a OEM stereo speaker going out on my Chevy Silverado LS truck, and he had one laying around. Probably, from another install. But, the price was right on and it works great. I highly recommend Folsom Car Stereo for your vehicle sound and security needs. read more

What a good guy! I was having issues with my system that I didn't purchase from him originally. I reached out for some help hoping I could bring it in and have him resolve the issue. Instead he took a few minutes and walked me through the solution on my own. I will be in for my future work. Thank you so much. read more

My Toyota 2000 4-Runner was giving Bill a seriously, difficult--well, actually, a horrible, noooo, that word won't suffice . . . EGREGIOUS time when I chose replacing the Toyota manufacture-installed, car stereo replacing and installing in late January 2017 with a 2017 Kenwood digital, bluetooth stereo system with new speakers. For some inane, unreasonable problem, my 4-Runner didn't like the installed Kenwood stereo system so, the stereo kept registering a "WIRE ERROR" 'out of the blue,' countless times . . . just driving down the freeway, not touching the stereo . . . "WIRE ERROR"--returning practically weekly in the month of February: Poor Bill had checked, re-checked, re-wired my 4-Runner's ENTIRE stereo system, amplifier, tracing wires, re-connecting over FIVE times!!!! All the while, I really think my 4-Runner was smirking at Bill with utter contempt. BTW: I also had Bill install a car alarm system due to the defunct 2K alarm was disconnected . . . That's another soap opera I wish not divulging anytime in the future. Anyway~Returning to the car stereo soap opera drama: That's it, 4-Runner . . . Bill is going to replace the Kenwood stereo with a SECOND stereo system, ok? At this point, I was seriously thinking I should give Bill a bottle of Rogaine because I envisioned Bill pulling his ALL his hair out! Humpf~My 4-Runner wasn't going to tolerate THAT replacement stereo and MADE SURE the second, replacement stereo didn't work, either! "WIRE ERROR": Bill was replacing wires, checking this, that . . . (- _-)~Sigh! So, the first week in MARCH . . . Bill please don't throw in the towel, please? \(-_-)/~AUGH, Bill decided replacing the current/second Kenwood--please keep in mind, Bill replaced the FIRST Kenwood stereo with the SECOND stereo system in February! I pray--hopefully and I do mean HOPEFULLY PRAYING, my 4-Runner will accept the THIRD (three is a charm, eh, 4-Runner?) upgraded, Kenwood stereo! My 4-Runner was being so treacherous, filled with utter contempt like Stephen King's "Christine!" Gee, 4-Runner~Why didn't you like the previous, Kenwood stereo systems!!!???? Getting a tad picky, aren't you, 4-Runner, eh? So far, a few days after installing the THIRD stereo, not one "WIRE ERROR" message has indicated on the screen so far! Well, Bill~Just call me if you want me to give you a bottle of Rogaine for pulling your hair out--JUST IN CASE, ok? Please accept my utmost, humble apologies for my 4-Runner behaving so badly by giving you such an EGREGIOUS difficulty installing a Kenwood stereo system! read more

The owner Bill is a national treasure. He is super knowledgeable and expertly skilled. I've worked with him on a few projects and had him diagnose and repair some issues. He's always fast, fair, honest, and friendly. read more

I had trouble putting in my stereo on my own, and had asked Bill if he could do it. He was helpful enough to send me the info i needed to finish setting it up. appreciate this a lot. read more

Bill knows his stuff. I had my new Toyota truck's factory system upgraded and now it feels like I am rolling around in a concert hall. Clear highs, accurate midrange, and solid bass from all speakers front and back. Beautiful. Max volume is way more than I can handle and the system handles the full dynamic range of eclectic music with ease. Super clear, piercing even. The installed sound dampening makes the vibrato of a bow on violin strings an exquisite, moving experience. Since I put 375k miles on my last ride, I look at the upgrades, although inarguably expensive, as worth it. If I put 200,000 miles on this rig, that's at least 400 hours of "concert time". Well worth the cost. The install was on time, clean, and delivered when promised. If you want the best, you've found it: Thank you for the music. read more

Folsom car stereo and Bill is the bomb. He truly cares about his customers. I have been a business owner for 40 years and Bill has the right stuff. I would not use anyone else. I tried 10 other shops that were close to my install and was getting really frustrated. Folsom car stereo came through and did a amazing job. Thanks Bill and Folsom Car Stereo. read more

Bill provided great customer service in fixing an audio issue on my son's car. Bill was quick to respond to our call for help and very accommodating to get my son in for an appointment to look at what others might consider "too small a job". Bill treated my son with respect and effectively trouble-shot the issue quickly getting to a fix at a very reasonable charge. Thank you Bill!! read more

Bill from Folsom Car Stereo installed my dashcam with front and rear cameras. All cables and switches got neatly hidden along the roof and behind panels I didn't even know my car had ... Of course both cameras work as expected and the installation looks great! read more

Drove all the way here (I live about 45 minutes away) to find a sign on the door that says due to Covid considerations the store is open by appointment only. Not a happy potential customer! read more

Does fine work. Installed an audio system for my car, and it works perfect. If you need something done right, this is the spot.

I didn't actually come to this shop for an instal but I spoke with the owner who was very kind and even offered to walk me through learning how to install it myself. It's nice to see a business owner that takes pride in not only the results of their work, but the reputation of their brand. I definitely recommend coming here, even if based on their professionalism and attitude alone! read more

When I checked Yelp prior to my visit I thought maybe the Yelp reviews were hacked or something. No place is that great, right? I went there today and I can testify this really is a 5 star outfit. Besides getting an amazing system for my truck with a backup camera the service was utterly amazing. White glove professional. Definitely a local independent who is worthy of visiting. read more

Everyone once in a while you do business with the kind of people who go above and beyond to make sure your experience is the best. Last summer FCS put in my Kenwood Excelon head unit and subwoofer. Both installations were done well and the look was clean. This summer I had a Kenwood Excelon amp and Focal speakers installed. Again, well done and the look was clean. So...I did have an issue once I got the car home and began adjusting the EQ. The amp cut out and only the head unit was working. Got up the next morning thinking I'll drive to FCS and have it looked at...unfortunately the car wouldn't start. Called AAA and FCS...AAA showed and jump started the car and after speaking to FCS, Bill, drove 20 minutes to my location to make sure everything was O.K. with the install. Everything checked out and Bill was right, I just happen to have a bad battery which my car maker replaced free of charge. I was just very impressed with FCS willingness to go the extra mile(s) to make sure everything worked. In my experience businesses don't normally do high quality work and follow up to make sure everything is the way the customer wants it. read more

My used car needed a head unit upgrade and I had been shopping for a replacement for more than 6 months. I created a worksheet with all the competing head units, but I was not finding everything I wanted. I contacted Bill at Folsom Car Stereo, and in a couple days, identified the unit needed, to include all the desired bells and whistles, on my worksheet. When I picked up my car, I was so amazed at the sound quality. Although I have had JBL and Bose systems with additional amps, and upgraded subwoofers, I never experienced the quality of sound, features, and resolution of my head unit. It is amazing! read more

Husband bought a 2017 Fiat Abarth and at age 74 he bought his final bucket list item. He loves jazz and Fiat didn't make Sirius XM a priority so it wasn't included. He looked around and found Bill at Folsom Car Stereo. Bill put in the necessary component for him to have jazz music thru Sirius. Great job, no hanging wires or cables and no components showing. This morning we easily programmed his fav Sirius stations and he's 100% happy. Thank you Bill for doing an amazing job and getting Lee on his way. WOOHOO! read more

Bill did a great job replacing the stereo equipment in my Porsche 911. I am very picky and was very impressed with his work. He is very knowledgeable and his pricing seemed very fair. I would definitely recommend Folsom Car Stereo! read more

Upgraded the ol' stock stereo and haven't spoken to a passenger since (because the stereo Folsom Car Audio put in there totally kicks a$$)! Bill and his son took great care of us! They ordered parts from across the country, installed and delivered (including having to drive to another dealer) on time in spectacular fashion! I'd recommend them to family and friends! read more

I have used Bill (owner of Folsom car stereo) since late 1990's to install speakers, GPS systems, blue tooth, back up camera, stereos and HD TVs in my cars and RV. From my Jag to my RV his work is pristine! I guarantee that there is no finer, more meticulous, and knowledgeable shop in California bar none. I first saw Bills work on Brad Millers car (sac Kings) I was so impressed that from that moment on no one has touched my vehicles other than Bill. Not only is Bills work the best and most reliable but his pricing is unbelievable! I just picked up my RV tonight after having Bill install two HD TVs and 4 speakers powered by an amp that blows me away! If you want a custom install there is no one even close to the workmanship and pricing that Folsom car stereo delivers! Bar none. read more

I called this business a few days ago to get an idea about how much it would cost to install a radar detector in my Cadillac. I had all the parts. I was quoted $40. I made the trip from So Sac to have it done today. Suddenly the quote is now $100. I had given them the full details of the work I wanted done, and the price quoted included a military discount. Classic bait and switch. I am not happy about wasting my time to go to a place that sounded welcoming, but far from it when I arrived to take them up on the quote. I left angry, and won't return. read more

I knew coming here I was going to get good service. I was not let down. Straight up quality business. They kept me in my budget (even though they don't carry mediocre quality stuff) and I believe it was bill surprised me, when I went to go look at my speakers in the rear of my jeep he also fixed my hatch!!!! It wouldn't lock and he just goes " no biggie just something I do." I'm like ummmmm I love you! Everyone go here for car audio things read more

Walked in with an amo that wasnt getting power, and in 10 minutes the owner found the problem, ran in grabbed some tools and the part I needed, hooked everything up and sent me on my way. This guy really knows his stuff. I will go to no one else...EVER. read more

I would Just like to say THANK YOU BOYS (Ross Jackson and Bill Werner), for the excellent customer service. I had just moved here and my Mobile Entertainment needed to be updated for mapping out the area to get around. I called several other car stereo places in the area and they informed me that my system could not be updated and my only choice was to buy a whole new system($1700-$2300) Thank you again for all your help with the research and taking the time(3hours) to install Yours Truly Jade (happy to refer you to friends and family ;) read more

Folsom Car Stereo has installed stereos, speakers, alarms, remote starts, Bluetooth devices and probably more for my family. Do you know why I keep going back? Because they do great, quality work and they have it done when they say it will be done. Bill is always fair and communicates well. I tried another shop when they went through an ownership change and neither the workmanship nor scheduling were as good as Folsom Car Stereo. I highly recommend them. read more

Bill is a true artist when it comes to all things audio. I have had him install multiple systems into my vehicles over the last 15 years, and with each install he is mindful of my budget while providing the best possible system to meet my requirements. In addition, I have seen Bill build enclosures into cars that look better than factory. I have seen him customize installation locations that I would never have thought possible. He has built cars from the frame up to install the most integrated and intricate electrical systems, and has maneuvered into the smallest spaces to install sound and lighting in boats. Folsom Car Stereo does so much more than audio. Bill has the experience, knowledge, and skill to provide the best sound while preserving the quality and structure of the vehicle. He does the kind of work that you would expect from a professional, and guarantees 100% customer satisfaction. It is increasingly hard to find individuals with as much pride in their work. read more

Folsom Car Stereo is a first-class shop. The true test of customer service is when not everything goes right. I had a technical issue with my vehicle that prevented FCS equipment from functioning properly. Bill could have said, "Not my problem.", but he finally found a solution that worked for me. Thanks again Bill and David. Job well done! read more

Honest, high quality guys. Call them and they always answer my questions. Bought a high quality amp from them and they were very reasonable. Taught me all I needed to know and had great recommendations. Thanks FCS read more

Got a back up camera from Folsom car and stereo and Bill did an A++ job. He knew which camera was the compatible one for my 2016 Mercedes C300 . I have to admit many shops in town including the Mercedes dealers in EDH and Sac refused to fit one. I am extremely happy with the outcome. Great prices and workmanship ! read more

Awesome quality, exceptional customer service and very reasonable prices! 5 stars! Thanks!! read more
