[QUOTE="dj2606, post: 7900759, member: 644373"] yep loose ground. The shop that installed it rigged the ground down with three screws because the ring terminal was 5/16 diameter. Do you think the sub could have blown because of this? When I got it to come back on it rattles, and doesn't really hit. Right now I have the rca unhooked to not cause further damage to the amp. This is the third mistake I have found after they installed the subwoofer and amplifier. First was negative battery cable wasn't tightened properly (kinda nerve racking driving down the interstate and the car cuts out). second was the pipe connecting the air filter to throttle body wasn't even put back on just left hanging in the engine compartment. They better replace the subwoofer free of charge, if it is indeed blown!!!!!! Either way thank you guys helping me find the issue. Anyone familiar with the pioneer 80prs? [/QUOTE]
