It could be a few of these problems. I would say check the remote wire at the amp, and then the ground wire at the amp. Does you battery die when you leave your car sit for a while?

on your amps speaker jacks if you have L+ and L- (or R+ and R-) connected to the same spaeker it will cause this pounding. you need to connect L- to R- for one speaker and L+ and R+ to the other spaeker.

I would check for a good clean ground and possibly the polarity of the speaker wires

the first answer on the list should be the right answer, u may need a new amp afterall. BUT, u said when the stereo is off u still get the same problem? well, the remote turn-on wire for the amp might be getting on/off/on/off/on/off pulses from the deck itself! Or the relay inside the amp where that wire hooks up to is stuck clicking and keeps switching on/off/on/off/on/off and so on ..... check for these 2 problems b4 you go out there and buy a new amp. good luck.

check the ground, make sure its a good chassis ground not close to anything else. also check all the grounds, the battery ground, the stereo ground

make sure your using 8 gauge running from battery to amp and 8 gauge for ground. As well use 10 gauge or lower going to sub. when you run your wires make sure power is run on one side of the car from battery and audio and rem on the other so there isnt any frequency. As well amp and sub sound be around the same watts if amp is more you might blow sub if its turned to high

Your amps probably over used and coil may be condensing
