If you're looking to upgrade the sound quality in your vehicle, you know how easy it is to get sold things you don't actually need. That's exactly why I appreciated my experience at Stereo USA Plus. The owner took the time to answer all of my questions, explain my options, and gave honest advice instead of trying to upsell me. You can tell he genuinely cares about helping customers make the right decision for their budget and goals. That level of honesty is hard to find these days, and it's the reason I'll be coming back for future upgrades. If you're serious about improving your car audio and want someone you can trust, I highly recommend checking them out. read more

I have nothing but gratitude to offer to the owners/operators of Stereo USA in Covina. While I was completing my own installation of an LED kit for my 2020 Nissan Kicks I needed to buy T-taps. The store Harbor Freight did not have the right size in stock. I walked to their shop, asking if I could buy some T-taps from them. The owner very graciously said, "You can have for FREE. How may you need". I was excited since I did not have to wait to order online or wait for the delivery. These guys gave me, for free, plenty of T-taps that helped me get my installation completed. I offered to pay them in cash, they said, "No, save it". A wonderful, compassionate way to help a human being in need. Receive much thankfulness and gratitude from my heart to yours, Stereo USA Plus, may you enjoy much health, success, and happiness. Thank you !! read more

Stereo USA Plus - They gave me their business card. - Car Stereo Installation Near Me - Covina, California

I went to stereo USA to find a stereo with a rear camera for my son's Toyota Tacoma and we were able to find a good quality stereo and camera for a reasonable price. The owner was great and assured us that the Work is guaranteed and if anything goes wrong to, please bring it back to him. We had some technical difficulties and we took it back and they were able to fix what was wrong just like you said. After three years screen on the stereo was damaged and he was able to get us a new unit at a discounted price since we are returning customers. I strongly recommend anyone that needs stereos or back up cameras or a sound system installed to come here. Thank you! read more

I've been going to place for over 10 years and the customer service is great and the products I've gotten in the past are always great quality. I got work done and had to go back a couple of times for and they never charged for the fuses or anything. Other places don't want to honor the warranty or give you a hard time but not here and that's why I recommend it plus you can't beat the prices. read more

Second time back and the boys continue to amaze me with their amazing service! From my Can am to my classic truck Stereo USA does not disappoint! read more

Do not come here or let these people touch your vehicle. Worst place ever!!! I brought me truck which I rarely drive to this place for door speakers. I purchased mid grade Focal speakers ( Access 6x9 & 5x7 ). After some time the speakers started sounding funny so I took my truck to a licensed Focal dealer for inspection. The technician discovered that Stereo USA Plus installed the wrong speakers, they installed at 5x7 speakers in a 6x9 spot. Furthermore they charged me for access speakers but installed Universal which is the lowest level. Basically they charged me then switched the product while I waited for service. I wouldn't trust these guy with your vehicle at all. I brought the receipt and the speakers plus videos of the speakers being removed by Focal technician and the store manager got hostile when all the information was presented to him. The manager started yelling at me making the comment the I wanted free stuff when he was clearly in the wrong. I had to ask him repeatedly to not speak to me disrespectfully. He went as far as threatening to call the police, which I encouraged him to do. What a complete narcissist, when clearly confronted with wrongdoing he became aggressive then attempted to play victim. I would challenge anyone who has had services at this business to check you vehicle to see if they installed what is on you paid for and on the receipt. I will be going to the court to file a claim against this business. We'll see is the manager try's to get crazy with the judge the way he did with me. BEWARE OF THIS BUSINESS - BUYER BEWARE - ID GIVE THEM A ZERO FOR THE WAY THEY HANDLED THEY'RE FAULTY WORK AND RESOLVED THE SITUATION , BUT I CANT read more

I brought my truck to stereo USA and spent 8k I got all my speakers replaced in a brand new truck GMC AT4X! This truck came with a full Bose system I wanted something better. From the day I took my truck in to a year later I've been to this shop 36 TIMES this is not an exaggeration. I installed 4 Memphis 8 inch subs with a custom box. The subs kept blowing because there's not enough air in the port so that was probably three or four visits then finally change the subs out to another brand and only did two 8 inch subs. I had to leave my truck there for four days to get a new sub box made then those subs ended up having multiple different issues so then i had to pay for two more JL W7 8" subs that was $1200 more but he claims it was a great deal cuz he wasn't able to warranty the other subs that ripped. My amps have never been set properly and that's why the subs kept blowing and my speakers kept having issues. I've had the front ones replaced twice then the back ones replaced twice and then the left rear speaker has had continuous issues to where I've brought it back seven different times left it there overnight multiple times i've had to Uber there and back multiple times never been compensated every time it's just all bringing the car in. We'll get it fixed. now I'm at the point where I guess I just lose the money and go somewhere else. This is gotta be the worst customer service. My wife is absolutely disgusted and how many times I've brought my vehicle back-and-forth to this place that it's literally caused us fights. Don't use this place read more

Paul was very helpful to me and had quick and fast service ! Very clean place great customer service

Have a few complaints about this place and they do not help once they take your money you're on your own ever since I took my car. I've been having problems after problems and now I can't even drive it. I changed the starter change three batteries change the alternator and it still don't drive. Another thing I'm upset is they told me one price and then at the end they tell you a different price then you're stuck be careful do not pay upfront. Don't make the same mistake. I did. You call the owner and he doesn't know what you're talking about. Never again think twice before going here.They promise you and I guarantee the work then they don't !! Not a happy customer I paid over $2000.00 read more

Paul and his team are wonderful! They installed a stereo system in my daughter's 2009 Highlander. It works great! Great customer service and extremely informative. The installation was done within a few hours. read more

4 speakers were replaced, no remote, fm didn't work. Bill wasn't broken down properly and of course you came up with a generic response. Not worth half of the $1850.00 you charged...funny how all of a sudden you have a complete breakdown of the charges! Remember giving me this receipt?!? read more
