I’ve never installed a amp before and I’m curious about one thing. So I ordered a small “compact” amp for my boat to power four 6.5” speakers. Nothing special just want better sound and little louder. My question is how do I hook this up?? Its pre wired and has a “HI INPUT” and “SPEAKER OUTPUT” both with colored speaker wires coming out, the HI INPUT just has speaker wires, the SPEAKER OUTPUT has the same wires but with a pigtail connection and a blue remote on/off wire. My thinking would be the side with the pigtail connection which is the “SPEAKER OUTPUT” side goes to the back of the receiver and the “HI INPUT” side wires straight to the speaker wires from the speakers. Then again I could be completely wrong because I’ve never done this. The manual isn’t much help.
