Are you goign ot use a perko switch or relay/combiner, ect to hook all yoru batteries up? to make is easy on me, I used a perko, and run on batt #2 (Golf Cart) and only ever switch to #1 in a non starting situation (low batt #2). All my boat power (pumps, stereo, PP, acc) is off batt #2, yes I do get some "nosie" thru the speaekrs that is audible at very low volumes when the blower, bilge pump or ballast pumps are on. Both batteries are on trickle charges when the baot is not in use.
