got a kenwood x812d and a kenwood x542. both in good operable and cosmetic condition. all original paperwork and packaging included. looking for 200 each plus shipping. 410 shipped for both. these are great amps and the mono block is 1 ohm stable. it puts out over 1000 WRMS at 1 ohm and 919 at 2 ohm and i cant remeber what it pushes at 4, prolly around 700. the 4ch is also 1 ohm stable and is 88 WRMS per channel at 4 ohm and 124 WRMs… in fact im just going to copy and paste the info. the only reason im looking to sell is to upgrtade to kicker SX series amps. i still have all the original packaging and paperwork for these amps.
