Rewiring the stock deck would not be required in any situation I can think of.
Assuming that the deck does not have RCA pre-amps (a likely eventuality) then you would simply need to acquire an amp that accepted speaker level inputs, can drive three channels and preferably has seperate crossovers for the channels.
In this scenario you take the wiring from the rear speakers and run it to the amp from the amp you drive the rear speakers and the amp. Obviously with a low crossover on the amp and a neutral(ish) one for the rear speakers.
eg:
HU--->Front Speakers
--->Amp (via rear speaker outputs) ---->rear speakers
---->Sub
Wholesale re-wiring does not occur unless you replace the stock HU in which case it is simply a matter of installing an adapter harness between your new HU and the wiring loom. So in an important sense (unless you're like me and solder the new units harness in because you're working in an old car...and save $20) re-wiring never occurs.
As far as whether a simple speaker upgrade would do the job, given the bass requirements I doubt it - a good measure of what the difference will be is asking yourself is there distortion when I turn my HU all the way up? If there is then new speakers will improve this and enable louder volumes. A more precise measure is to compare the rms output of the HU and the speakers - lets say the speakers are 10w and the HU is 15w (example from my mates lancer pre upgrade), the installation of 30w speakers will only yield a 5w increase in perfomance and hence a HU upgrade is on the cards in order to experience real gains.
My suggestion is amp+sub+new speakers and consider a new HU down the track as installation in a new car may well get messy (and expensive) eg many do not use a standard DIN mount. Furthermore if you lay off the HU now you can take advantage of improvements in HU that are just around the corner, afterall HU are the most fast moving in terms of developement. In a year ipod, usb, mp3 cd, dvd, HD-DVD, etc etc will all be far more mainstream and you can reap those benefits.
