Great little amp for tight spaces
This is an excellent amp for a subwoofer. The amp has its limitation, as the size suggests, but it is very capable, configurable. I really liked the fact that is has the option of using high signal or low signal for input, time saver!

What a nice amp.
Tiny but effective amp. Perfect for sub requiring 500w RMS. Setup/calibration was easier that should be possible.
