Bought this amp to power a set of Rockford component speakers and bridged two channels to power a Rockford sub. All this is in my 19' bow rider. The amp sounds good and I had no issues with it when first installed. It's getting to the end of it's first season and I am starting to have overheating issues. I'll let it cool down and it turns back on but then a few songs later it'll power down again. Debating on what to buy to replace it. I guess you get what you pay for.
