I had an awesome experience with Stereo USA Plus for my stereo system and installation. The team was professional, friendly, and extremely helpful in guiding me through the best options for my vehicle. They carry a great selection of top-quality brands and make sure everything is installed correctly and sounding amazing. The installation was done efficiently, and they took the time to walk me through how everything works before I drove off. Great customer service and quality work—highly recommend them for car audio upgrades and installation!

My son bought a new display and rear view camera for his car. We did the best we could installing it but had a problem with the camera ( bad instructions) install. I was all out of ideas so I drove to Stereo USA Plus and told who I’m assuming was the owner that I would pay them to help me with the camera. He told me that he won’t except any money from me and had one of his techs walk out to my car. He showed me two wires that the directions never told me to hook up and said that was it. I tried it and it worked. That was very kind of them, I am definitely coming back there when my son is ready to customize his car.

Was referred by my local mechanic. I needed a minor repair and a part installed to my existing car radio. Moe helped me out and I am happy to say it was an easy, pleasant experience. I let him know what I needed, he was pleasant and respectful, I didn't feel uncomfortable at all; was not pushed to get anything I didn't want. Highly recommend them. There is a Starbucks about a 10 min walk away; we chose to wait there - in case you don't want to hang at the shop.
