Looking to trade for a good head unit ( Eclipse, Sony or Alpine preferred) or a lower power SQ amp, class AB. Monster Power's top line cond. to prtect your stuff and add SQ (most noticable on CD/DVD player, then preamp) Reference 3500 in black. Has analog meter to monitor line volts and nice 24K gold buttons. I am lacking about 1/4" height to fit it in my cabinet,bummer. Standard width. Near perfect cond. Mike
