hey all, picking up a new to me 2007 Moomba mobius lsv, it has no tower speakers and just stock boat speakers and deck. im probably going to order a pair of 10inch wet sound tower speakers, I also want to add a 10 or 12 inch subwoofer under cockpit, also depending on the speakers that are currently installed I might swap out the four 6.5 it has. now I have no problem installing things or running wires. but I don't know how many amps I would need. any help would be greatly appreciated. also pictures if you have any on your setups.
