I have a 1989 ski nautique 2001. I have 4 ws pro80s running off a syn2. I used it all last summer and it worked perfect! I have a 1000A cranking battery and a 6mnth old optima d34 running off a Perko switch.
I just bought 4 Polk db651s for the inboat speakers and would like to power them with a syn6 so I can also run a ws XS-12..
My boat has a 60amp alternator and I'm just wondering if I should be thinking about another battery or larger alternator with this set up!!
