Great Product

Amp looks good and does the job. Sleek red LEDs make it even more amazing. Only con is it does get a little toasty, but overall, I would by this amp again.

Decent amp

Bought this because its made by Maxxonics. Did lots of research and found them to be a great brand. Crunch is just the budget end of Maxx. The amp its self was bigger than i was expecting. Had a very good weight to it. did not feel light and ceasy. One big CON is that the power inputs are the same size as the speaker out puts. meaning its impossible to install 6ga wire. i had to cut away half of the strands in order to clamp down on the positive and ground leads. But over all for the price i cant complain. installed in in a boat vertically with inputs on top and outputs on bottom. im driving a pair of Kenwood KFC-6994PS and a pair of Kenwood KFC-415C. together they sound fantastic. cant complain. this amp makes em' sing. from the bumpy lows to the crisp highs. (this amp was able to make the voltage drop on our boat which has a 50 amp alternator when we cruising down the lake. no distortion at all!!)

Nice, affordable amp.

I bought this amp to push a couple 10" subs. Hook up is pretty straight forward.
