I installed an aftermarket subwoofer and amplifier in my truck. A few months later, my battery began draining within 2 days and couldn't be jumped from another car. The only way it would jump start is if I used a jump start pack. I proceeded to disconnect the subwoofer and amplifier from every single spot it was connected to the truck, so there was no aftermarket product attached anywhere in the truck. But the truck continued to drain so I took it to BestBuy Geek Squad, where they told me I had a parisitic draw from the stereo. I bought a new stereo and had it installed but a few days later, the battery was fully drained again. I know it is coming from the stereo/stereo wiring somewhere because if i remove the stereo fuse, then the battery will stay charged, but I have no idea what to look for now that I have installed a new radio
