Before season projects - Upgrading a few things and I have a couple questions.

Went ahead and uncovered the boat and got it all cleaned up to hopefully go to Acme monday.
I'm upgrading my battery bank and subwoofer arsenal.
Last season I had 2 12s- 1 under the helm, 1 under observer locker.
This year I plan on doubling that as long as it's possible to put 2 12s nicely beneath the helm. Boat is a v215 sanger.

Also, where does everyone stash their batteries? Mine are in the rear lockers now and are coming out to fit my 1000lb bags. I'm thinking 4, maybe 6 6v's

I forget who's boat it was, but someone had a v215 done by acme, sub boxes were blue, had 4 JL's, were those 15s??
