well, im gonna be selling this amp soon and i was gonna see if anyone round here was interested. it the black series PPI PC 650
rated at 50X6@4ohms rms, 100X6@2ohms rms, and 200X3@4ohms rms bridged. 4 stereo channels and 2 sub channels. its enough to power a whole system nicely. has a buttload of features. crossovers, bass boosts, etc. its a really nice piece, and came out in PPI's prime.....EXCELLENT condition and is in use now, its working great! PPI has been known to underrate and if you heard this amp youd see why, its very clear, accurate, and precise. cost $800 new.....typically selling on ebay for $300-400. if you are interested i can do $300...
