Bought this last week for my 22' cuddy. Its powering a pair of Bose 131's in the cokpit and a pair of Pioneer 1640's in the cabin. Sounds great! Power seems clean....and the amp runs really cool. Not too many hot days yet...but I drove it hard all day last weekend and it didnt even get warm. Granted Im running 4ohms...so Im not pushing it too hard really. Im not using the crossovers...but the amp has alot of nice features. I love the full range RCA outs...they give plenty of signal to my Bazooka....unlike the last amp I was running the exact same way. My system really came alive after adding this amp. A steal at $129 in my opinion. I gave it a 4 on durability because Ive only had it a week. Lets hope its solid as a rock.
