Summary: The price of this unit attracted me. It had plenty of power for what I was going to do in a marine enviroment. It is powering 2x JL 7.7's and 2x JL 6.5's in the cockpit of my boat so the power requirements matched right up. Sounds great and I am very satisfied. The only negative I could say is that it's a big unit, bigger than I anticipated. Making modifications for a location to mount this amp was the bulk of the install.
