Alright i got a 12' Pioneer with a 800w american pro amp. So the sub does not work right now. Everything is connected securly and used to work just fine. Now all of the sudden, when your drivin or have the car just sittin there no bass will play and it will just kick in once in a while for about a second. All the wires seem secure. Whats my problem?

 

Is your amp giving or taking.....jk

Take some pictures and give a much better description. If the american pro is over a year old, you might have exceeded its design life.

 

check your fuses and test for voltage at the amp.

 

i had that problem recently check your grounds, fuses, connections double check everything, use a voltmeter

 

YA CHECK UR FUSE HOLDER 4 UR POWER WIRE. ALSO I WOULD CHECK UR ALTERNATER ITS HAPPENED TO ME BEFORE
