A few years old. Polished aluminum cover. Complete heat sink air tunnel with high speed quiet fan. Completly tunable in every aspect. Upgradeable with plug and play chips that can push power over 1000w. Amp is in perfect condition. I believe its runnin 600w on 3 channels. It pushed a full set of Focal K2 highs and mid drivers along with 2 JL Audio 12 W3v2 and did it with no sweat. This amp is the shit PERIOD. Have no use for it. Paid $999 a few yrs ago will sell for $550 obo. Can post pics if serious buyer wants them.
