I agree with the peice by peice part, but don't spend all your dosh on the most expensive HU. Here's what I'd do and in these stages as well
#1 HU....basic BRAND NAME...sony, pioneer....etc etc..This will be the biggest upgrade that you can do to your system, make sure it has RCA outs.
#2 Front speakers, don't waste your time on a set of splits, I don't think that you're looking into that way anyway. A nice set of 5 1/4 coax's will work just fine. Remember bigger isn't always better. Remember mounting depth when buying your speakers.
#3 Rear fill, if you're in a bind........6x9's cheap and not too bad for what you get, personally I'd get the same set as your front speakers and mount them in the rear shelf.
#4 Amp: nice four channel that you can hook up to all of the speakers, make sure that the amp can later be bridged to 3 channels, I'll explain that now. Amp must have a built in crossover.
#5 Sub, basic sub box mounted in the boot, a 12 works just fine. Bridge the amp 2 three channels and run your front set off two channels and the sub off the other bridged channel. You can run your rear fill off your deck..
Some notes in closing...............party packs suck.....you'll install it, hook it up and be very unhappy with the results.....150rms sub would be perfect, remember when buying an amp, to buy one that can be bridged and has an internal crossover, it'll save you money in the long run.
hope this helps
