So we bought a 2008 Sunsport 22v and evidently it’s had several different amps in it. It currently has pro 60s(trashed surrounds) on the tower, kicker in boats and 2 kicker 10” 4 ohm subs. The in boats are driven off the head unit and the tower and subs are driven off a single jbl ma704!!!! We have a kicker non marine 500x1 amp we’re going to put on the subs and will drive the tower off the jbl bridged. My question though is about the perko. I should have the starter wire on the common and the batteries on 1 and 2, correct? The sound system battery was the only one tied to the perko. Just trying to clean everything up for this season and do surgery once it gets too cold.
