I bought this amp blown and I had it repaired at Amp Repair Center. The bus bar was hitting one of the coils which caused the power supply to blow. The power supply, PWM chip and 4 drive transistors were replaced as well as moving the bus bar back from the coil and applying glue between to the coil and the bar (to prevent the problem happening again). This amp was worked wonderfully since I have had it fixed. It is pretty clean, about a 9/10 cosmetically. It has a couple small flaws but nothing really noticeable. I will have to get some pics of if. I'm selling this for $725 shipped. I'm not moving on this price and I'm not interested in any trades. Just cash. Here's my feedback thread. http://www.caraudio.com/forum/showthread.php?t=263320
EDIT: This amp comes with no warranty other than no DOA.
