Not sure if you already made your decision on what to buy but I recently had Wetsounds installed in my boat and am blown away with how great they sound.
X2 on the wetsounds I am running their stuff in my own. I posted this question for a buddy on a budget. This Skar stuff looks like good stuff priced right. He ordered two pairs of 6.5" s. Mike
The New M3-650X from JL ( M3-650X Coaxial Speaker can be used with as little as 20 W per channel, for best audio performance we recommend amplifiers capable of between 75-100 W of continuous power per channel.)
