Going a different direction with the next boat audio system so selling my stockpile of D7 amps that I have collected over the years......they don't make these any longer. These are american made hand built amps, what a novel concept. I was going to use 2 4-channels and 1 2-channel and bought the others for spares. Anyway, they are all for sale...$350 each.
