Audio Gurus - I need some advice.

Not clear on what you want each component to do but if you want to use all of the gear you mentioned, I would focus on the front imaging using the Ovations, ran by your 250/2's, use the 8" as midbass, and the 10w3 as the sub. Not really a good idea to use both the 8" and 10" as subs. Forget about rear fill on this tiny cabin. You have a bigger problem installing the 8"ers. It is a lot of work to integrate the 8" to the front stage, not impossible but a LOT of work. You'll need another amp to run the 8's. Old school installs incorporated midbass on the rears but does have an impact on imaging. Because it is such a small cabin, it might not be noticeable in a small and confined space like the Z unless you have high tech ears. For me, I'd be able to tell the difference in imaging and staging with rear midbass. Install options would be to install the Ovations on a kickpanel and mod the **** out of the doors to incorporate the 8" midbass drivers or floor board the 8" drivers right in front of the seats facing up while the Ovations stay on the door or the kick panel -- the floor board install is the least practical option if you ask me. Having 8" mbass drivers in a small car makes for a very challenging install but with the gear you mentioned and if done right, you'd kick *** on SQ with the least amount of processing. I just luv the thump of a midbass kick --- especially from an nicely driven 8.
