For 120x4 amps, either a SoundQubed Q4-120 or a Crescendo C1100.4.

4 slots as in speaker holes? Where are the holes located? Did you say in the door and the dash?

Why not a couple of 3.5" full range drivers up front. That's what I would think about doing if I had 8's in the doors. You could probably put a couple in the back but unless you attenuate them out of your front stage you'll get some interference.
If my thinking is off someone just chime in.

im doing 4 8 inch mid bass on all doors i was thinking the 4 tweeters will blend good

Whatever comes off that windshield is gonna be loud anyway. Reason I say 3.5" full range drivers is because they can cover a wider frequency range than tweeters can, and considering your using 8s in the doors you may need something that can pick up where the 8s leave off.

What is in the cruiser currently?

If these are 2 ohm, am i loading 18w on these speakers if the diagram says 2ohm? what will happen if i powered these with 75watts @ 4 ohm, how much wattage will it get?

first off imo I wouldn't get a two way driver, just get the woofer. And the diagram is showing your stock speaker ohm specs. You need to decide what speakers you want to replace your stock with and find an amp that satisfies your new speakers requirements. I can't make any suggestions maybe someone else can.

Sorry, Caleb, never trained myself up on Pro Audio as it's never been something I'd considered for myself. Have to pass this on to someone else.

OP, you'll probably get a better answer from SMD than here for what you're looking for.

The components he's using lead me to believe that, yes.
