yes your amp is the phd2 like i mentioned earlier. it takes 0 gauge power and ground.

 

I have one of those amps dead in my office! Always wanted to try and fix it but as of yet havn't figured it out... I should take another crack at it.

I remember my biggest problem when i tried to fix it before is that they sanded off the label on alot of the IC's so it's tough to figure out what they were being used for
