Biggest speaker size for Cavalier door

Ok so ive done alot of searching on other sites as well and finally figured out that the ZR800's will fit. So the plan is to have the ZR800's in the door with a set of ZR650 components in the kickpanels and 2 W7's in the trunk. do the W7's sound better in a ported or sealed box. and also what speakers would you recommend in the rear deck? stock is 6x9 and i would like to stick with JL speakers but they dont make a 6x9 in the ZR model. is there something that i could substitute??

ya im thinking i want to port the subs, i just dont like giving up half my trunk for a sub box. i already had that problem in my 97 with the RF P1's. oh well i might have to bite the bullet and just go for it. dont use the trunk much anyway and there's still the option of pulling the subs out if i have to for a day or two.

As far as the 6x9's is there anything that JL makes that would compete with the ZR series speakers? if not what would you recommend? i know you said Infinity or JBL but what model specifically in each?
