Firstly, if upgrading your headunit, you are going to need about $400 just for the fascia kit.
Do you want a single din headunit or a double din touch screen monitor? If you want single din, you can buy one anywhere between $150 (entry level) - $500 (top range).
If you want double din, then it could set you back anywhere between $700 - $2000. My advice if looking for a double din is to wait for a bargain on ebay, or for specialist dealer sales (such as those offered by Phatt Audio Concepts in Braeside, and Freeway Car Audio in Dandenong)
In terms of speakers, only do the fronts as the rears you don't get much benefit from. Save about $100-200 on rear speakers and invest the money in other items. Also, go to audio stores and audition speakers. I have Hertz HSK-165's and they sound good to me, but everyone is different and have different tastes. So what might sound good for me, you might think is too sharp etc. So audition speakers before you buy.
If you want bass, you are going to need a subwoofer, and if you want a subwoofer, you will need an amp. What I did is bought a decent 4 channel amp, and have that powering my front speakers and subwoofer.
Finally, are you going to be installing yourself? Or are you going to get it professionally installed? If you are installing yourself, allow about $75 for a 4gauge wiring kit and an afternoon to install. If you are going to get it professionally installed, steer clear of installers such as JB-Hifi and go to a place with a reputation for car audio installations. The two mentioned above are really good, although you will find that Phatt may be booked out for quite some time. Also try Tower Car Audio. But do expect to pay between $200-400 just for installation (not including wiring kit, and depending on what you are getting installed).
If you don't want to change the headunit, what you can do is get a Line Out Converter (which I will have for sale shortly, but they are about $30 from JB Hifi) and connect it to the speaker lines from the headunit. Then send that to the amp and run front speakers and subwoofer from amp.
My recommendation is either do the Line Out Converter method above, or change just the headunit and see if anything else needs to be changed. In previous cars I've owned, changing the headunit was enough to satisfy my needs.
