Best damn car stereo shop around!!! I wasted time going to 4 other local shops before coming here. Junior was great with answers, advice and equipment for my DIY installation. Hooked me up with a quality amplifier, wire, connectors, fuses etc. and I needed every part of it. This 70-year-old car never sounded so good. I would highly recommend this business for quality customer service and equipment. Thanks again Junior!!! read more

Excellent Service, very knowledgeable and great work!!! All the staff were very helpful!!!!! read more

I came here to get some wheel spacers for my 54 Bel Air. It was before thanksgiving so they were really busy making bigger money deals with customers. The place is organized. Customer service is great. Everyone was nice. read more

Junior and his crew were willing to get me in today completely last minute and spontaneously to try to help me with my car problem, even though he wasn't sure if it could be fixed or not. Good, honest dude. Great business. Definitely recommend. read more

They sound insulated my car for reducing road noise. I am happy with the results. Price was not the most expensive or most cheap quote when I shopped around. This modification is worth it if your car has lots of road noise and your car has excellent speakers. I can hear my subwoofer better. The lows sounds deeper. The difference in sound is minor and maybe only audiophiles would notice the difference. read more

Fantastic service Fast Great install Fixed a previous vendor's screwup with wiring Highly recommended! There was a hiccup with scheduling, and Junior took care of it with high urgency. Top notch. read more

Great service, great people. Highest quality products. They will take care of you and get your sound proper without question.

Amazing experience with Junior. Never doubt this man at all he will hook you up and put a smile on your face. Can't wait for him to install on my Subaru crosstrek read more

My husband and I stopped by Junior's Car Stereo during their annual Father's Day/Graduation sale to look for some outdoor grill speakers for one of our cars. From the moment we walked in, we were greeted warmly. Even though the store was busy, the staff was attentive and made sure everyone was taken care of. We were helped by Pavel, who was friendly, knowledgeable, and took the time to show us different options that would work with our setup. He explained everything clearly and made the whole process easy and enjoyable. We'll definitely be coming back to Junior's for all our audio needs. Great service and great experience! read more

This review is long overdue. Like seven years overdue. We took our Ford excursion to juniors for a pretty significant left, I can't remember exactly how high. We also purchased tires and rims. My husband got exactly exactly what he wanted. He was very impressed with all the options and communication from the staff. Fast-forward to seven years later. My husband replaced the tires (not purchased at juniors) and I'm not sure why. We were having an issue with the tires rubbing in the wheel wells making a horrible noise so we went to juniors to see if they could help us cut out the wheel wells so that the tires would not rub. I took the truck and spoke with the owner, he was able to look me up by my last name and find the work he had previously done in the system. I asked him for a quote and he kindly replied that there would be "no charge". I was beyond flabbergasted, especially in a time like this where everything cost a fortune. Huge thank you to juniors for going out of the way seven years later to help a previous customer. your generosity has gone along way, and you have gained customers for life. read more

They receive three stars due to time taken to complete the repair of my infotainment system. Job was completed and system works well but was a longer repair and more costly ( hourly repair) than was expected from what I read about DIY installations. read more

Junior's Car Stereo - Subwoofer - Car Stereo Installation Near Me - Fremont, California

I own a 2012 Toyota Camry and my stereo/CD player stopped working. Junior's crew after looking at my car, asked questions like what am I looking for and want. Hooked me up with a nice Bluetooth radio system...worth every penny, high value means aamazing sound and look. Service is #1. Highly recommend read more

Wow!!!! All I could say is Junior always aims to please. The creativity they did just blows my mind. Everything was hand made and fabricated from nothing. When i dropped it off I told junior just use his best judgment. Only issue it's too loud...lol. The Wet sounds just blows your ear drums. Thanks for another job well done. Truly a work of art. I have been coming to Junior since 2002, with all my toys....i just leave it in his hands. Thanks again!!! read more

I found Junior's on Apple Maps in 2022 and I'm so glad! I brought in my Kia Optima to install a Kenwood excelon touch screen with Car play, a backup camera, and a forward camera. The work was excellent and the customer service just as good. Junior personally talked me through it and got me all set up. Later I needed a minor adjustment on the tilt mechanism and he took care of it right away. I was so pleased that later, in early 2023, I brought in my 2nd gen Tacoma. I had Junior put in a 10 inch kenwood with ALL the bells and whistles, a backup camera built into a new tail gate latch handle, new speakers and tweeters in the front doors and sound-enhancing material in the doors! Also, new high/low beam bulbs (the best!) on that note: I had bought new headlights from somewhere else (shoulda got em here) and I tried to put the new bulbs in myself, couldn't do it right so I showed up without an appointment and he took care of it within an hour and charged me nothing! Please make an appointment tho!!! This man and his team work hard!! It would probably have helped them out if I didn't just show up, but just to show their commitment to customers. :) Highly recommend!! read more

Junior's Car Stereo - 10 inch multi function kenwood display with CarPlay, backup camera and all the goodies :) - Car Stereo Installation Near Me - Fremont, California

These guys are ACTUALLY the best at what they do. You can tell they aren't out to be the cheapest, they're out to be the best. Absolute respect for the good work and mindset of this shop. Detail oriented and knowledgeable. Definitely my go to from now on! (We won't talk about what they had to fix from the OTHER GUYS). read more

Took advantage of the Black Friday deal. Customer service was on point! Paval went through every option for me, described in detail what's needed and what's optional. They don't try to upsell you on anything or rush you to make a purchase. As someone who knows nothing about car audio, I came out feeling confident about my purchase and excited to hook up the sound system. Armand also helped with the transaction and rest assured me that I'm in good hands. The labor was a little more than I thought, but nothing is more expensive than having to redo a bad job. Will hit these guys up as soon as I get back. Thanks Paval and Armand for the great customer service! read more

I found myself in a bit of a tricky situation. While attempting a DIY installation of a dash camera in my car, I removed the A-pillar cover to route some wiring. However, putting that cover back turned out to be way harder than I anticipated. I ended up taking the car over to Junior's without an appointment and asked if he could help me out. He called one of his mechanics, who spent over 30 minutes working on it and finally managed to get the cover back in place. Junior kindly refused to accept any payment for the help. After some insistence, he allowed me to tip the mechanic instead. I left feeling like a happy customer! read more

Came here to get a Bluetooth radio installed, bass boaters, and also replaced damage plastic radio trimming. JCS is an incredibly reliable car service that works hard to maintain high quality customer service at a more than fair market price. Couldn't recommend this place enough! read more

These guys at junior are the best. HANDS DOWN THE MOST HONEST SHOP IN THE BAY! The give any advice you need and doesn't feel like they want to pinch you for every dollar when you walk in. 10/10 I recommend these guys to any one! read more

Supporting local businesses is key to growing our communities. That being said, we recommend Centerville based Junior's Car Stereo. The photos are from my 2011 Nissan 370Z Touring that was rescued by Junior and his design and installation teams. For this project, we needed a complete removal of the previous unit, broken items and most importantly the wiring. The previous installation was an unmitigated disaster. Broken components, bare wires, incorrect wiring, which led to my defroster dial and mirror compass not functioning. In addition, the equalizer and speaker configuration weren't working, and the system was underpowered. UGH! Junior's staff went to work and started by doing a complete demo of the system from cradle to grave. Once that was completed, they started the rebuilding of my stereo system, piece by piece. They even designed a cool, red "Z logo" cover (see hatch pic)! When Junior called me to pick up my Z I was excited to come to his shop, but I was floored after he walked me through what had been done. The system looked fabulous, but the sound knocked me out. No distortion at all, regardless of the volume, base, treble or music genre. The cost of this "Phoenix" or rising from the ashes was fair and to me worth it at any cost. Bottom line, if you're looking for a new car audio system do not look any further than Junior's Car Stereo where their professionalism and attention to detail will make your car's audio the talk of the neighborhood. OBTW - They also fixed my defroster dial and mirror compass! read more

Recently had a new stereo and alarm installed and it was done professionally for the value, noticed I had a seat belt indicator that was going away on my dash. So I called and junior said to bring it in and they would take a look at it. Long story short, they were having trouble clearing it due to the car was in an accident which I wasn't aware of and the seat belt module was defective and now it's working great. They took the time to help me figure this out to insure my safety. Thanks again Junior for your service, definitely coming back to get my beats next! read more

Great customer service, was very helpful and friendly on assisting for a quota. Great management and very respectful with great prices

The guys at Juniors' car stereo are the best. I had little knowledge of sound systems and made my classic car sound system bad ass. They took the time to explain what was needed for what I was looking for, made an appointment, and they got me all set up. This place isn't out here to scam you or add things you don't want or don't need. I also got a flat tire on my spoke rims, and all the other tire shops wouldn't change my tire, but this place did. Check them out. read more

Talk about 5 star customer service. Junior's team were all very nice, knowledgeable, and super helpful. I had a system already installed almost 20 years ago, and it needed some updating. With their help, they gave me all the available options to choose from, did a quick, and clean installation of the upgraded components. My car is back to its former glory, however it sounds better than ever now. Thank you all and I will be back and highly recommending them. read more

I called today to get a price quote, there was no answer. I checked out their website. No information whatsoever. So the only option was to text. Albeit, I have an older model car and I wouldn't be spending tons of money on a car stereo. However, all business is business, and great customer service brings referrals. (I drive an older car, but I'm actually an entrepreneur and a digital marketer.) Sadly the response I received was terrible! In fact, the automated response had better customer service than the person responding. If I could give you negative stars, I would. Sad, that this is how you treat your potential customers. read more

Junior's Car Stereo - Car Stereo Installation Near Me - Fremont, California

Not sure if the guy does good work or not. All I know is I been here like at least 3 times over the years and the guy comes up with the most outrageous prices when he doesn't want to do work for you. Compared to other stereo shops in the area he triples the price instead of saying no we don't do that here or we only install stuff you buy here. That's the whole thing if you come in with your own gear he doesn't want to do the labor. Just say that instead of wasting people's time. Go anywhere else but here. read more

Definitely the best car audio customer experience I've ever had! I came in looking to replace a subwoofer I had stolen from me. Junior, who I'm assuming is the owner, walked me through the wide selection, listened to what I wanted(clear and accurate sound) and gave me the perfect recommendation. Due to some manufacturing defects, one of the 2 10s I bought had to be replaced. Without any hassle at all, junior and his team offered a replacement and swap installation within less than 45 minutes. I could not recommend this place more for all your car audio needs. Thank you Junior and team, I love my new subs! - Nick L Ramirez read more

Juniors car stereo is the only place you should bring your vehicle to get, sound system, wheels, alarms etc. I just had my second Viper alarm installed on another vehicle I own. Junior and his staff are professional, straight forward, informative, friendly and makes you feel comfortable, explains the best option and price they are super clean in their work and honest. read more

Recently had an impromptu wiring situation arise (late at night) and popped over without an appointment to see if they could help. They were kind enough to do a diagnostic and repair on the spot (it was a trunk wire that had frayed) and I am SO GRATEFUL! This is a great value and saves me a great deal of time as I could not open the trunk without pulling the emergency release from inside. Thank you all! Please give Junior's Car Stereo in Fremont a chance if you are new to the area. They are well worth the wait (if you need an appointment) and are fair and honest. read more

My amp kept cutting out over and over I called JCS just to ask questions and he said to bring it in and he'd look at it himself. Found a broken fuse and a new Allen screw for my ground wire. Within 10 minutes fixed it and had my speakers sounding like they were brand new. Top tier service cool ass guy great experience! read more

I have been going to this business for over 20 years. Less than a year ago, they recommended and installed a Kenwood deck on my harley but apparently it wasn't water resistant even though we don't have cages to protect us like cars do. It's gonna get wet. You guessed it, It got wet but the owner is not going to stand behind his product; he's going to blame the customer. He did hesitantly say he'll look at it in a month from now but that it's "probably fried." Translation, "Buy another one or go away." Great customer service, Guy. I will not be back. If you are having a radio installed on your motorcycle here, proceed with caution because you may get stuck with an $1,800 dollar bill and a non-working product. Thanks for nothing. read more

Junior is kind and professional. He sold me everything I need to swap out my stock stereo in my 08 civic for a price very comparable to anything I could find online and gave me plenty of useful tips on how to install myself. Will come back for anything else read more

Great customer service and knowledge! I came here first, a year ago to get a sub and amp I purchased online. The installation was very clean and everything was up to my expectation. Pricing was reasonable for labor and these guys will definitely take care of you. Fast forward to today, I came in because my old sub that I picked up elsewhere last year took a dump on me and I wanted to pick up a new one. I spoke to Junior through Yelp a few days before to discuss some options and came in today and dealt with AZ. The whole process was smooth and was surprised with the amount of selections they had. I ended up finding the perfect sub that would work with my current amp and AZ took care of me. I wouldn't hesitate to take my business here over and over as these guys know what they do and leave you feeling good. Thanks guys! read more

Junior's Car Stereo - Single 12W3v3 H.O. Wedge, Ported, 2 Ω - Car Stereo Installation Near Me - Fremont, California

Junior and his team of installers did a wonderful job of installing and tuning my sound system. Junior and I discussed what I wanted done and the sound I was expecting to accomplish. His team did an OEM amp bypass, retaining OEM head unit, installing an Audison DSP amp for the front stage and an Audison amp to drive the subwoofer. Wiring and installation is first class, mounting the amplifiers via custom mount under the driver seat. His installer even cleaned my messy crossover wiring without asking. Junior truly listens to customer needs and will be flexible to small changes. Thanks, Junior. read more

I came in about a month ago looking to purchase a subwoofer box for my 12 inch alpine sub. It was close to closing time and I don't remember the name of the gentleman that helped me out. He pretty much broke down how the subwoofer boxes with all the different shape and sizes, type of wood used, and interior insulation work and help with sound. Very informative and allowed me to put two different sub boxes in my trunk to see how they would fit. First box took up more than half of space in my trunk. I like the big space in my trunk and wasn't willing to sacrifice it all. Second box was a a single ported truck style angled box which didn't take up all the space in trunk. I ended up purchasing the second subwoofer box. Bigger box will sound better for a 12 inch sub the gentleman said but as I mentioned earlier. I like having space in the trunk. I didn't have the sound system installed here but the gentlemen told me if I wanted the setting to be properly set to give them a call and they would do it. I think I'll give them a call when I have time because at times the sound sounds muffled with certain songs. read more

I had a complete sound system installed in my new car. I picked it up today, just like it was promised. I am so impressed with the sounds. The job was very well done. I love my car even more now. Beautiful work. Thank you read more

Best place in town! If you want people you can trust working on your car this is the place to go.! They actually care and take time to do work right! I was having an issue with my alarm system (was not purchased at juniors) and I stopped by to see if I can get a new one or something and he actually just fixed my alarm it was a wire or something. But the fact that it's a busy Father's Day weekend he took the time to take a look at my truck and actually fixed it. I really appreciate it! Thanks again!! read more

I had to get a really simple fix done on my aux port for my Lexus, and when two other places told me they couldn't do that kind of work, Junior was able to do it in less than 10 minutes. No hassle, no fuss kind of guy who was able to do the job I requested super efficiently. Will 100% be going back to him for my car repair needs in the future. read more

My son went in and ask if they can help hide some wires from his stereo and Junior took the time to stop what he was doing and help him. We will be going back to have a new stereo and speakers installed. Prices are fantastic and employees are great!!! read more
