Loud "thud" when powering up amp!?
Well recently I noticed an major issue with my setup. When I start the car and the head unit fires up with no issue. The remote for the amp lights up for about 6 seconds then I hear a loud thud from my subs... then the remote light turns off... basically the amp is shuting itself down. I have no bass and only my door speakers work. Nothing has been changed or moved around the past 2 years.
What I have done so far...
- checked remote wire (repluged it in)
- checked all wires connected to head unit (all are soldered and heat shrink wraped) and appear fine
- checked in-line fuse near battery (150amp anl)
- checked amp fuses (40's)
- checked all wires from amp inc. ground, 12v wire, sub cables
- checked battery terminals and cables
Any idea's what may be the problem? I'm thinking the amp may have an issue??
note: specs in sig....

You need to narrow it down to either the deck or the amp. You could get a 3.5mm jack (headphones) to RCA and use your mp3 player as the audio source.
Try this and report back with the results.

Thanks Mr. DatSUBishi but I already checked that. I did however notice something when removing the amp cover a few minutes ago. 3 of the 4 large 80V capacitors are bulging at the top. Not good. Sending it back to manufacturer.
Thanks for everyones input...
