I've had this PL model #P850D amp for quite awhile now and hasn't failed on me at all. Good all around solid amp. Had it powering my 4 10's and did wonders to them. Mind you, the amp is 1 ohm stable and my subs are wired to 2 ohms final impedance. I was only using 1/3 of the amps power. Has a few somewhat deep scratches but bought it as is from ebay and is refurbed. Comes with instruction manual but no original box. First person to come up with 100 bucks it's yours also seller to pay shipping....which will be around 20 bucks.
Wattage:
350x1 into 4 ohms
550x1 into 2 ohms
850x1 into 1 ohm
Built in x-over and bass boost (0 + 18dB)
