it may be a vacuum problem. you should pm me what city your in so i can see how much it would cost to get out there, i am kind of interested. i cant tell does it have any rust behind the rear wheel wells or inside the door jam?
the crunch gp3000d's are probably what he was talking about and yes they are about the best dollar per watt amps out right now. if you have the money though i would go with sundown or try the new diablo audio 2500's.
thats not that bad i had an opti 2000d that my buddy bought and ran it at .33 ohms on a stock alt and battery with a stinger spv 35 in the back and half the board is melted. i will see if i still have pictures.
im sure you will but make sure its not a scam, that sounds like to good of a deal.
edit. not calling you out raadkins16 just a good price and there have been lots of scams lately.
