cabin speakers/amps

What do you guys use Car or Marine speakers? Does is it really matter? What is the model you are using? I'm thinking about using Infinity 62m marine speakers. Does anyone have this kind and do you like them.

This is what I'm thinking about getting
A6004T Audiobahn Amp for my speakers
A8002T Audiobahn Amp for the sub
62m Infinity Speakers for the cabin. Tower Speakers will come later
Polk DB124 sub 12 inch.

Does anyone have any recomendations good or bad on the above set up? The rear speakers are going to get wet (kids) that is why I'm leaning towards a marine speaker.

Most car audio speakers hold up pretty good in marine conditions. Unless there getting splashed all the time with water I'd stick w/ the car audio. As far as the amps I have a a8002t and its been running great for me over the past year. No problems and pushes quite a bit of power. they aren't as effiecient as other amps but for the price ($150 on eaby w/ shipping) they are hard to beat.

just put silicon grease on the wires from the rear of the cone to the connectors every couple of years and dont buy paper cones..

MB Quart "Reference" series 6 1/2's in the cabin, Zapco amps. I don't really see a need for "marine" specific speakers.
