Just picked up my first boat a couple of weeks ago. Found a steal of a deal on a 2003 Moomba Mobius LSV, so this is my first post here and ice melt cannot come soon enough! Anyway to the fun stuff for winter time...

It had stock speakers but aftermarket head unit. The speakers were pretty much trash so I picked up 6 Rockville 6.5" 2 way speakers and I got a 4-channel Rockville amp from a buddy that I was hoping to use. I need some advice on the best way to wire this stuff up. I have been playing around with different combos, but I don't know enough about amps to know which is best to do. Specs of the speakers and amp are below. I also noticed that the 4 rear speakers are wired together. Both speakers on the starboard are wired together with only 2 wires at the head unit for rear right. Same with the port side with rear left. Not sure if that is normal for most setups, but that is the way it is. Really looking forward to hearing what you guys have for suggestions.
