sounds like your amp is overheating... but could be something else... what kind of fuse are you running, whats the headunit/amp/subs? and how do you have it wired? do you have a speaker level converter on it? I tried one of those speaker level converters, and I could'nt get any sound (well I could, it was just so damn quiet I could barely hear it) and when I did a direct speaker level input to my amp from the front speakers it worked like a charm.

first off ever heard of sentences? it makes it easier for us to read.

secondly are the positive and negative wires running closely together because that can cause the static that you are getting. not to sure about the problem with the amp thou.

my guess is somethings are touching that shouldn't be touching with the smoke issue that you have goin on.

Did you ground it properly? To the metal chassis?
