I'm starting to look outside the marine speaker realm. Many more 2ohm speaker options at half the price.

 

Just blew the woofers on my first set of Polks that i purchased in July. Not impressed with these at all. Very disappointing!

 

Seriously, check out Memphis speakers. Have them in the truck too, outstanding speakers...

 

I ended up going with the SS540 and 4 Polk MM651's. Have not had any problems as of yet. It ROCKS, at 70 or 80 need to watch not to turn it too loud as it hurts my ears. Much better than stock.
