I am selling an almost new Kenwood KAC-8105D mono sub amp. It runs very cool due to the built in fans and it has a very small footprint. Easily puts out the rating. 300 x 1 @ 4 ohm and 500 x 1 @ 2 ohm. I used it for a month and a half and blew my sub (200 over rms). I'm selling because I need an amp that is 1 ohm stable for future plan. I'm asking 120 shipped. It runs 150-200 new. I have original box and everything that goes along with it.
