Recent Review: This is a great place. After our radio stopped working following a battery/alternator service as a local car repair shop (Far East), we tried in vain to get the car repair shop to take responsibility and fix it. After many weeks of hassle we gave up and took it to DSP. I called on Friday, and it was fixed before noon on Saturday. The gentleman (Eddy?) on the phone was polite, knowledgeable, and efficient. He made the appointment for appointment for 10 am Saturday. When I arrived he was ready, and had all my information I gave him on the hone already up on his computer. I told him that the other car repair shop (Far East) had tested the speakers and concluded that I needed whole new radio unit, and offered to sell me one for a hefty dealer original equipment price. DSP said they could install a better radio as a cheaper price, but said they would try to fix the existing radio first. Just in case, I picked out a radio and authorized them the replace it and was ready to pay several hundred dollars. In about a half hour DSP called me and said they fixed to old one and the radio worked and the car was ready to be picked up. This is an example of an honest business that could have installed a radio and changed me for it, but instead repair the old one and charged me less. I would go back to DSP in a minute for any car stereo issue. They are technically competent, honest, polite and efficient. Who could ask for anything more? Don?t let the alley location intimidate you. The shop is clean and modern.
