Overall, good bang for your buck. I have it wired at 1ohm(yes its 1 ohm stable) and I am getting just about 600wrms. The settings are easily changes and it is a very decent looking amplifer as well. It pushes a 2515, along with another amp, without any problems. My only gripe is that you have to tune the gain almost exactly(Volts = SQRT (600W x 1 ohms) or else the amplifier likes to go into protect when the volume is up too high.

Overall, I have to give it a 7/10 for the price. Its no sundown, but it does the job.
