Its not the first time ive installed audio systems in a car but it is a first time with a problem trying to get the sub to work.So I hooked everything up as it should, Turned on the Sub settings on my Pioneer HU, the Amp LED light was on so it had power and the subwoofer was working just fine. But a few minutes later the bass just shut off and the subwoofer just stopped working. The LED light on the Amp was still on so it had power but the subwoofer wasnt working. The amp couldnt of blown the subwoofer cause the amp only gives 500 watts and the subwoofer handles 800 RMS and Peak Power of 1200 watts. So I bought different amp thinking the other one was fried inside so I got a Lanzar Amplifier with 800 watt max and hooked it up the LED light showed it had power but the subwoofer still didnt work.I also changed the Terminals on the Sub box but still no luck. So I bought a 1000 watt Kenwood sub thinking the sub could of been blown but still gave me the same problem with the New Amp and Sub!? I made sure that the RCA's and Remote were conected on the HU right, I even changed the RCA's and the Remote wire, Bought a thicker Power wire and Ground wire, Changed the wires on the Sub box, checked fuse on the amp, fuse on the power wire, fuse on the HU, Even fuse in my Fuse box lol . The Subwoofer settings on the HU showed it was on. I just cant figure out what's wrong! Can Someone PLEASE HELP ME??
