I have a 12 in alpine type r sub with an alpine amp and it was working fine until my buddy bought this big painting for his room and put it in my trunk and one of the hangers fell off and was laying on the amp where all the wires connect.. i didnt notice until i went to check out the amp and make sure it was still on and everything was hooked up still.... but now the problem is that the sub still hits but only a few times and then goes off and then comes back on and back off constantly... the amp is always on too.. could the amp have just taken a s**t or the sub???
