Good amp for the price

This amp was a good one for the price.It was strong and reliable and put out close to, if not more, than what it was rated at. Crossovers on it are pretty broad and strong as well, so that's another plus.I would/will buy again.

Poor performance

I would certainly not recommend this product to anyone because it's seems to be very weak the (4) channel version seems to be a better buy.
