SQ setup, a little challenge for you guys

Ok its has come time to completely overhaul my current setup in my car.  I have a 98 Dodge Stratus ES.  I currently the type-r 6.5 components in the doors and I had the 6x9s in the back but I disconnected to put more power to the 6.5s.  For a sub I have a 10 sealed in the trunk.  Currently the sub amp and 4 channel amp are audiobahn and so is the 10.  I got them before I became a member here.  Yes I had confession, only 200 Hail Marys left..  Anyway the system has been ok.  Now Im not looking to bash Audiobahn, I just would like to upgrade.  I have liked the sound from my components and really they are the only thing I want to keep.  My current head unit is a Kenwood x817.  I know you guys like alot of information inorder to help so here goes.

Here is the order I wanted to build in.  I would get everything at the same time if I wasnt going to school( Is it bad that I think my funds would be better used in upgrading my system than furthering my education).

• 1.) Front - I was thinking about keeping my current components and adding another set in kick panels.
• 2.) Sub - I am thinking either a 10 or 12.  Im not sure whether sealed or ported.  I dont want to be heard a mile away. 
• 3.) Replace Amps - If I should replace these first let me know.
• 4.) Headunit - By this time my current will probably be dead.

Budget:  I have no problems with Ebay, we are great friends.

• Speakers: up to $450
• Subs: up to $500
• Amps: 600-800 for both - if this is too little let me know, and I will just get them individually so I can spend a little more
• Headunit: 450max

This budget of course is based on what I would save for. No Im not rich.   I am hoping to start on my next  paycheck or so.  I will be installing things myself, as I did with my current setup.  First time to build box and would be first time kicks( if these turn out bad then I guess I will have them made (What is good priceto have these done) I have an 4 gauge from the battery, do you guys think Ill need to upgrade.

I live in Fort Worth, Tx and between here and Dallas I have quite a few places I can listen to things at. 

Big stores: Tweeter,  CarToys, of course Best Buy, Circuit City.

Brands that shops have: Adire(According to their site), Eclipse Subs, Diamond CM3, JL - of course,  Cadence

If anyone has any other places around here please let me know.  To me if Im going to throw down the money I want to do the research. 

Oh yea almost forgot, I listen to just about everything. Rap(Lil Jon, Tupac, etc..), Rock/Alt( Counting Crows, Seether, Hendricks, Steve Vai, Santana, acoustical guitar),of course there is the girlfriends selection (Alanis, Switchfoot, U2, Sheryl Crow ). 

Thanks for reading this long request. I appreciate, and thank you guys for sharing your knowledge (I have learned quite a bit from you). thanks in advance for taking this challenge

Here's what I'd do:

If I had a $500 sub budget I would get the Brahma 15" or Eclipse 15".  I would use a sealed box for SQ.

Memphis Audio seems to provide a really nice value/price point right now on amplifiers.

Lots of drivers can work as the midbass.  I'd probably go with the Koda 6 drivers. 

Head unit.  Eclipse is my suggestion.  Others like Nak and Alpine.  Listen to some and see what you think.

Good luck!

What? Since when is a 15" driver "rap only?"  Since when is a 15"  more "boomy" than a 12"?  A good 15" in the proper enclosure will sound just as "tight," "hit" just as hard, or whatever, as a 12".  If you've heard boomy 15" drivers then you've either listened to people that designed them that way or didn't know what they were doing - or a little bit of both. 

Find me a reputable reference that says, "15" drivers are boomier than 12" drivers.  You won't be able to.
