Different Sub sizes

Is it ok to have like 2 12s and 1 15 if there running off 2 different amps?

You can do it, but next to impossible to get it sounding right. The subs will exhibit different response curves, mechanical limits, etc.

oh, i though if different amps it was fine

What subs are you speaking of?

No. That has very little to do with it. It's all about cancellation. Two transducers with different group delay will cancel each other. You cannot avoid this with woofers of different sizes. There is literally no advantage to doing what you want to do. It doesn't look cool. It doesn't sound good. It's really just a fail all the way around.

I'd get a 18" and a pair of 8"s and install them in the shape of Mickey Mouse's head. Shit would be dope...

I realize you're probably wanting to be loud, but undoubtedly you're wanting to play music as well. Factor that in with your lack of box building skills and you're going the wrong direction. It is usually recommended that each 15" sub have 4 cubic feet of net volume. This means to run 3 you would need at least 12 cubic feet for a maximally flat response curve. Good luck figuring out how to mount them in there and still get 12 cubes net.

I would have to suggest you save the money you were going to spend on those other 2 15's and get a nice box made for that trunk. You will be glad you did.
