I would only use the ProSport 20 as a shore charger while the boat was either docked, on the trailer or in it's boathouse. Not while using the stereo.

  1. Is there something else I should consider?



So if you are going to use a charger in conjunction with a Gen as a power supply then you definitely need to step up to a higher amperage and convertor class of charger.
I was planing on running the boat to it's sitting spot (cove), no gen set running. Then the gen set gets fired up running off the 12V output to the batteries or running to a converter off the 120V output to a converter. The gen set will run a little over 20 amps at 120V (or 144 watts at 12V dc.)

Havent got that part figured out yet.
  1. I guess I should be using feeding the gen set to a converter?


I also have a 6500 watt gen set that I can commander if I need, (sometimes it's good to have a construction company!)



The Blue Sea VSR and dual circuit manual switch (or auto AC relay to replace the manual switch) is an easy layout. I like supplementing the VSR with an AC relay since the shore charger will be in frequent operation and this will make everything totally automated.
  1. Can you point me to a single line?




Your subwoofer(s) will be the largest part of the current draw and will be one of the initial considerations in sizing your amplifier and charging support, battery capacity, etc.
In sequence, the boat will determine the best location and orientation plus displacement for the subwoofer enclosure. And that will then determine the optimum size of subwoofer and optimum enclosure type whether bandpass, bass-reflex or air suspension. The actual subwoofer driver selection should come later. When you get a chance survey the boat and scout the possibilities.
My mounting options are really very open (building the boxes will be the easy part) and since my original idea got shot, laid dead and has been burned til gone!

  1. Any suggestions on what I should be looking at?
  2. Under some seats on the bottom deck?
  3. On the bottom of the upper deck in a custom custom enclosure?


I have a full woodworking shop, and my buddy does vinyl work for me, so we can pretty much put the subwoofer(s) anywhere.

Thanks again for the help, I know it isn't so easy to "dumb it down" for an internet answer!
