MM455 & 465 - Amp questions...

Need Help! I just bought a pair of MM455's and a pair of MM 465's from E-bay for my boat. I will also be adding a sub (not sure what sub yet).
I am thinking of running an Alpine 5-channel amp (30 RMSx4 + 100x1). Is that enough juice or should I consider a 2-channel (50x2) for the 455's and a 3-channel (75x2 + 150x1) for the 465's and sub?
Any help would be greatly appreciated!

    Due to your suggestion, I am thinking about 2 JBL P180.2's for the MM455's and 465's. They put out 90/channel @4 ohms. Hopefully that will cover me! Is 90Hz a good high-pass setting for the MM465's as well as the 455's?

    Also,
    I just bought a JBL 600.1 (300 watts mono @4 ohms) for the sub. What Polk sub do you recommend with this amp? I only have room for a 10" sub in the boat.

    Thanks!

    Kim,

    Thanks to your suggestions, I will be running 3 amps...
    2 JBL @ 90 watts/channel: One each for the 455's and 465s
    1 JBL 600.1 for the sub.
    The JBL 600.1 amp will run 300 wattsx1 into 4 ohms or 600x1 at 2 ohms. It sounds like that should be plenty of power for even the MM100 or 120 (or maybe 2-10"s bridged).

    The last thing I need is the sub(s). I have attached a couple of photos to show my space problem. I think I have room to mount a 12" sub directly into the fiberglass under the steering wheel (conveniently a Momo!). The problem is that the enclosed area behind there is pretty large. It would almost act like a "free-air" installation. Would I have to build some kind of box behind there, or will one of your woofers work OK in that application?

    Other options: There is plenty of room under the closed-bow area up front, but I would be afraid of an echo-chamber effect.
    The only other place I can think of is behind the rear bench seat, but as you can see, the padding behind there is pretty thick. Would 2-10"s behind the rear bench work better than a single 10" or 12" in the open under the steering wheel?

    Any suggestions would be great... I can't wait to get this finished...It's lake time in Arizona!

    Thanks for all your help,
