Hey guys looking for some help. I have a rockford fosgate p500-2 amp and a 12" p3 4ohm(i believe) wired in bridge mode. Just recently when i turn up on the volume on my headunit if i turn it up past a certain point or a bass heavy part of a song comes on the sub kind of cuts off and starts to make a rattling noise. At first i thought it was maybe just up to loud and it was clipping making the sub go into protection mode. But now it seems to do it often and its really annoying me. Is it the sub or maybe the amp? I dont have any thing turned up excessively high gain is probably 1/3 of the way up no more than half way max. LPF is set to 80hz on the deck and amp.

PLZ HALP me get my wubb wubb back!
