ok so i jsut bought a jl audio 15" w0 that is 8 ohm. and i bought 2 12" w0's that are 8 ohm but are into 4 ohm in the box. could i get a amp that is 300 by 2 at 4 ohms and run the 2 12's to one channel and get 150 each sub. and run one channel to the 18" that is 8 ohm so it would go down to 150 rms which is what its recommended? and is it stupid to have different sized subs or will the sound be better? thanks

Very stupid to have different sized subs, either stick with 1 18, or the 2 12's, but not both. It can be done with 2 different sized subs, but very hard to do it properly.

Different sized woofers play the same frequencies differently from each other, the 18's will be playing at a deeper tone than the 12's and usually all just mudd's out sounding very poor.
