thumping noise
Theres this strange thumping noise that comes up when im in my car.
At times the music could be playing at a moderate level and all of a sudden the bass starts to thump extensively loud. I could lower the volume all the way down and the thumping is still there.
I typically turn the radio off/ on and it goes away. Im certain its my amp causing this problem.
Im using an audiobahn A8000T amp to a 12' L7. Just to be certain im going to replace the amp with another of the same.
Has anyone else encountered this problem?

I think Ill replace the AMP and see.

How long is your ground wire? Many problems can be traced back to a bad ground. Are the subs moving a lot when this is happening? A friend of mine had the same problem, even with the radio turned all the way down. Turned out he had a terrible ground. Wish I had taken pictures of that mess.

I may have to tighten down the amp though. I believe it does move a tad.

my roommate's amp did the same in his mr2, i got sick of it and beat the crap of it and it stopped for a bit but i ended up putting my spare amp in there. the amp was actually just too old and was abused so it was gone anyways.

thats the same exact thing i've been doing.
Once it thumps I pound on the amp with a closed fist. Then it goes away.

sounds like an rca is coming loose, or maybe internally the rca connection/wiring is fawked. a ground would cause it but not as frequently as an rca... make sure the radio is off when playing with rca's unplugging them and all. good luck.
