The amp is in good pre-owned condition. It does have scratches and scuff marks throughout but nothing major. I have bench tested this to make sure all channels work which they do. All EQs and filters work as well. I have not tested this in an actual vehicle. 40 watts RMS x 4 at 4 ohms (65 watts RMS x 4 at 2 ohms)125 watts RMS x 2 bridged output at 4 ohms (4-ohm stable in bridged mode) Ships Priority Mail in a box.
