Poly-PlanarME-60 4 Channel Amplifier - 120 Watts

Concept is great, great to power speakers on a jet ski too. Volume knob failed after a few months and cannot replace without purchasing an entire new unit (although second party volume knobs will work).

2 channels went out after about 30 minutes of first use. After I cut a stupid hole for the volume control, what a total waste of my day for this junk! If you want another chinese product that lasts 30 minutes or may arrive DOA, or an expensive paperweight, then this is what you want.

I put the on my boat with two mtx marine speakers. it really rocks those two and i still have two channels left. i have ordered two more for the boat. it will rock them. i have to turn it down as not to scare away the fish
