I have been using this product for almost a year with no issues. It works well with my 4ohm speaker even though it is designed for a 2ohm system.

I recommend this amplifier. It is hooked up to a 12” sub in a sealed box, producing deep and solid bass. The added bass knob is a great feature.

I found that the Powers 2 10-inch subs perform exceptionally well and produce great sound quality.

My son recently turned 16 and I wanted to upgrade his car audio system. I found a great deal on Amazon and had a friend install it. The system with two 12” kickers and an amp sounds amazing. My friend was impressed and is planning to get one too. Highly recommend this product for the price and quality.

The amp was as described, but I didn't realize it wouldn't fit my intended application. It was brand new and seemed problem-free. Amazon processed my return and refund quickly.
