Awesome amp for the price

I've had this for about a year and the price to performance is tops. This won't blow the roof off of your car, and is better suited to run your mids and tweets than to run a sub bridged.

It has to be underrated from the factory in terms of power delivery (or everything else is overrated, you decide). I was using it at maybe 30% of max gain before it topped out my OEM speakers on my GTI.

Its gets plenty loud with very little distortion even at high volume. And it is incredibly feature rich with crossovers, RCA pass throughs, high level inputs, etc.

Best of all, I have virtually no space to mount it but this thing is so small it fits anywhere.
