I have one Precision Power (PPI) 650 amp that is LNIB. 650 = 6 channels pushing 50 amps each at 4 ohms. The only amp you'll need. It comes with original box, owners manual, and sticker. Paid about $550 6 years ago when I was in high school. It was in my high school car for 2 years and I never got around to installing it in my truck. Now I need money, so it is for sale for $200 + shipping. I am also considering trades: Guns, knives, flashlights, packs, gatchets, anything... Email me with offers - the most I can say is no. I will try to get pictures up tomorrow.
