I went with the JL Audio amp. The 45 W is @ 12.5 volts, so when the boat is running, the figure /channel rms is 70W @14.5 volts.
I'm sure that it will be loud enough for what we will use it for.
Now, the only thing left to get is the head unit!! Any suggestions? I was thinking of the Pioneer DEH-P80MP. Anyone have any experience with that model???
For the rest of the system, this is what I have already bought:
Cabin speakers: 4 X Babb model 534
Cockpit speakers: 4 X Kicker KS65
Amp: JL Audio e4300
