Ok... my current set up is:
(6) in boat Kicker 6.5
(1) 12" Kisker sub in it's own enclosure (ported)
(2) Roswell R6 tower speakers
(1) Kenwood HU (not sure of model)
(1) Kicker amp
I am happy with the speakers and not looking to replace. I just want to get the most out of them.
So, is adding an amp an automatic "Add a second battery" situation?
