2 American Bass cx1200D's.. one of them has blown mosfets in the power supply and output section of the amp, the other is in hard protect. 100 shipped for both.
mtx 500d, it works but pulsates the sub when you trun the gain up. nothing burnt inside. $50 shipped. may be a simple fix. very underrated amps actually does about 750rms, fused at 75 amps.
two old school RF punches nothing burnt inside...not sure what they need a Memphis amp with gain knob...the pots need to be just right to work $100 shipped for these 3......
I have an AUTOTEK SS590.2, It turns on but no sound comes out. Pics of the amp and the inside. It also has 1 screw for speaker missing. Throw me a price +shipping.
