stereo upgrades order of importance

Ok cool, few last questions so I can price and build this in my head first. For signal processers the RF 360's seems over kill if I am only technically powering 3 channels. Is the cheaper MTX ok for this case? I still have to tap the rear speaker outputs to drive the signal lines for the sub I assume? Would a 40x4 amp work, but more importantly would 80w be enought to drive a 10" sub? And my most pressing issue; Should I just buy the damn 800 dollar head unit with all the nav and blue tooth I want with a set of good front speakers some sound deadening and call it a day. Seems like the signal processor, amp and sub could really add up to over kill for what I want. It seems stupid to me to put 700 into the electronics end and still not have the great headunit features of the aftermarket.
 
Just wanted to bump this to see if some of these ideas will work for you, or if we need to work another solution.

So what I was looking at was 200 in sound deadening, 200 signal processor, 100 speakers, 250 dollar amp, 100 sub + a custom box (I have never worked with fiberglass so this could be a train wreck) I figure in the 1000 range for everything which is just too rich for my blood. I will drop that on a fmic, fuel pump, standback, turbo, or exhaust system but sadly not my stock based radio.
 
I aimed high on the prices because I didn't calculate shipping and stuff. I am really hung up on the headunit. Would a new unit and some front speakers with sound deadening still sound good with out a sub for now. Most cars I add the sub first but I am just not feeling that in my "race car". I 100% appreciate the time you have taken to go over this and explain what you think is best I just worry that it is overkill for me.
 
I Do NOT agree. There is a lot more to be done. A processor to recalculate a flat output to the amp, sound deadening since this car is a tin can when it comes to sound, and you still need an amp to go with that sub. Also, a ported box takes more room, so now you've got to build a box that is larger then a sealed box by roughly x2, and end up with a boomier sound potentially.

People dont' realize it, but you can't fit just any sub into any box. Each sub has its own parameters that suit it best, and a ported box requires a precision build. Combine the level of difficulty with the amount of space required, then add on the very nature of a hatchback being a car made to amplify certain bass frequencies, and a simple sealed 10" box becomes the best solution for this car.

Other cars fare differently, but ported boxes belong at home, IMO (unless you are prepared to invest a lot of time and patience in building one made right. If you are, then you are in for a treat.)

Im not that stupid... i had a system in my last car:

No crap you'll need an amp and the dimensions of a box as opposed to a specific subwoofer is only common sense, and i dont think an 8" subwoofer would really rock his car sooo much that he needs to spend a couple hundred dollars on dynomat... im just simply stating that if he wants a little more of a bump, (IMO) all he really needs is and 8" sub (not all that powerful) and a ported box (which makes it sound pretty powerful).. a ported box does make a difference in loudnes and in decibles.. an 8" sub isn't going to be too expensive at all, and with the right ported box, it would sound almost like a 12" sub... (and of course with the right amplifier also)

fourthmeal, did you line your trunk with another material? it looks nice. Any threads with any more pics of your system?
