This amp has it all.

With the exception of Zapco C2K4, and perhaps Audison, this is the cleanest, most powerful 4 channel amp on the market, AT ANY PRICE. I bench tested this thing and it consistently produced 165 watts on all four channels at 4 ohm loads, AT 12.7 VOLTS!!!!! This was without clipping. I kept it on the bench for hours just to see how far it would go. You would have to MSRP well over $1,500 to beat this amp. Hands down, superior to any other consumer level amp,i.e.,(kicker,jl,alpine,rockford,mtx), on the market. THESE RESULTS ARE FROM THE BENCH, NOT FROM THE MANUFACTURERS BOX.
