Best Buy installed my system for me and I have had no problems.
Honestly it might depend on the Best Buy you go to, because the one I went to the Geek Squad team that installed my system was fantastic. Installed everything professionally, put my subwoofer inside my ported box, wiring job is fantastic, the amp was placed on the back of the seat and overall it sounds amazing. Installation itself took about 1 hour. Maybe you should try going to another Best Buy. Btw what do you have installed in your car? It will definitely help knowing what you have for a system. The amp you have could very easily be the culprit.
