Works good
Installed on older wake boat. Easy to wire. Love that the wire harness has detachable clips for easy removal once hardwired. RCA outs work great for my sub. Using to power two 8” wake tower speakers. Love that it has a volume knob not volume buttons. Pairs up to phone right away automatically once powered on. Hopefully it lasts. After install it did get pretty warm after playing music at loud volume for an hour or two.
