I pulled all the old speakers completely out, drilled holes for larger marine LED speakers, installed a touch screen Pioneer head unit, and have that ran through a 4 way amo for the 8 overhead speakers, and a mono amp for the subs.
I also have y splits to allow the TV to play through the speakers as well
