hey Im not to sure if this is the right place to post this, but I need some help, I installed a new head unit in my car, and after about five minutes it just turned off on me and wouldn't turn back on. My old factory unit worked just fine when I hooked it back up. I know the new head unit works because I have a power supply in my house that Im able to hook it up to and it worked just fine. I tried replacing to fuse to the head unit and Ive tried replacing the fuse in the car, but nothing. any help would be great.
