Poor ground connection?

Blown amp?

Several possibilities considering the very minimal info you've provided us with...

Amp went into protection mode... :0

Yeah, probably time for repair. The memphis amps i have worked on will keep pulsating on and off the protect light if some of the output fets are bad. This happens alot with the memphis amps that use the P channel FETs. I personally don't care for them at all... Some people swear by them.. Not sure if you Audiobahn is of the same old design as the memphis D class but sounds like it is doing the same thing.

It's thumping because it's trying to come out of protect; Disconnect the woofers from the amp completely and see if it comes out.

*edit: Turn the amp off before you do that.

alright well i got it to work for little while normally but then it went back. it only works at like a tenth of the full volume, any higher it'll crap out again. if it does i gotta reset it. i already disconnected the woofers and hooked them up again... nothing happend.
