Amp question...

Thought I would throw this out there for you stereo guys. I know this is a pretty bare bones set up but for now I'm comfortable with that. Just picked up a new-to-me used Malibu. The previous owner took out his amps and sub but left 4 tower speakers and 4 cabin speakers. The speakers are wired in parallel in sets of two so I have 4 wire runs to the amp location in the passenger storage. Each speaker is rated 60 W RMS at 4 Ohms. So, each wire run is 2 ohm.

My question is this. I just bought a Kenwood KAC-X40 4 channel amp. It was on sale and the sales guy said it would be plenty. It is rated for 65 W x 4 at 2 ohms. The speakers in the boat are nothing special and I do not plan on blasting it so the rider can hear it. So.... will this amp be enough power to power all 8 speakers and still sound decent? I was also looking at the Alpine F300 which is slightly less power but close to $100 dollars cheaper.

In the future I'll upgrade to Wetsounds or something else. My plan is to use this amp to power everything for the time being, then, when I upgrade, I'll use it to power just the cabin speakers and re-run all the wiring to have dedicated lines for each individual speaker (no parallel wiring). Any suggestions? Thanks!
