Sub Door Question, Redoing the Premium Audio package Options

[jbcustom]

So I decided to finally go full aftermarket with the speakers in my celica. problem is that I have the premium audio package. I have a total of 8 speakers in my car.
These include:
8" paper woofers in the door
4"midrange components in the door
3/4" tweeters in the door
6x9 in the rear.

I have already purchased a Pioneer 8600MP for the HU. And pioneer's 3 way 6x9 and 4" speaker. Would any one have any recommendations on subs that will fit the door? I want sound thats loud and crisp. I was going to go with Polk Momo 8" subs. Any further suggestions?

I am going to make sure to get pictures of the project. I plan on moving the battery to the back. I have to do all custom wiring because of a funky "not standard" premium amp (the wiring harness for the 89+ toyotas doesnt match). Any comments would be more than helpful.

subwoofers play lower, and woofers are mid ranges that play midrange frequencies... if you want the best sound get some components... you will want to power your woofers and speakers with an amp... id power everything off the amp and the 6x9"s off the deck.. actually...if you want an 8" subwoofer in your door, it needs to be free air capable... Kicker and JL have some of these that can suit your needs.. anyway as i said... power the Speakers off the deck, and the component set and sub/woofers off the amp... what kind of components do you have anyways?
