Need Help Creating the rest of my System.

[raz1121]

So i was going to have it all finished for a christmas gift but now i am going to breckenridge, co to ski for my gift so im going to have to do all the work myself on my system for a professional install cost a lot.

08' Sedan Base Model

So far i have.
Infinity Kappa 693.7i 6"x9" 3-way Speakers
Polk Audio MMC5250 5-1/4" Component System
Pioneer DEH-P7000BT CD Receiver


What im looking to do is get a tight sounding 10" sub for my trunk and put an amp to my speakers. I am planning on just buying a sub box. Also im thinking it would be a good idea to dynamat on the bar that the 6x9s sit on and some in the trunk and behind the front woofers. I'm looking for any input possible to help me get what im looking for. I have been looking at a 5ch amp on crutchfield http://www.crutchfield.com/p_065GT50...ch=5+ch&tp=115 but have heard its better to run two seperate amps. Any help will be appreciated. Thanks.
