OK. Be prepared for a long post!.
I had the same setup as you. Stock headunit, stock speakers and no underseat or parcel shelf sub.
What I did was I said I didn't want to spend cash on fascia. (I already had a decent headunit at the time, so I sold it). Ended up getting a small 4 channel underseat amp (4 x 50W RMS, gave 150W RMS when bridged across channels 3+4). Installed some clarion speakers in the front and then I got a 8" sub to install in the stock location on the parcel shelf. All of this was going to run off the stock headunit.
Yeah, it was OK. But the problem I had was the amp wasnt providing enough power to the sub. So I swapped the amp for a PDX4.150 (4x150W RMS and 300W RMS when bridged). This was perfect for the sub. But now the front speakers couldnt keep up. So swapped them out too. Replaced them with what I currently have (Hertz HSK-165's).
System went well for a while, and then my mate was selling his Liberty. So I scored his fascia kit. Picked up an Alpine IVA-W502 pretty cheap second hand off ebay and when testing it out I blew my 8" sub. From there I went through 3 12" subs in the space of 2 weeks because I didn't like them. Ran with an Alpine Type R 12" for a while. Problem was my 4 channel amp wasnt giving it enough power. So I ended up getting a PDX1.1000 for my sub. This was a good setup. Then I found a great deal on a JL Audio 12W7. Got that and have never looked back, and have not changed anything since, I'm that happy with the sound system at the moment!
The BIGGEST difference was when the headunit was changed out. The sound compared to the stock headunit was just so much more clearer. Everything sounded smoother and much nicer than with the stock headunit. Not to mention the fact that the added features of the aftermarket headunit was great!
The point I'm getting at is set yourself a goal of what you want. And save up or do it in stages!
My recommendation is to get the fascia kit and a decent headunit. Get that installed and you may be happy with how it sounds. From there, if you feel as though you want more bass, you can easily install an amp and sub. If you then feel you want louder speakers, you can replace the factory fronts (forget about the rears, wasted money there) and possibly install a 2 or 4 channel amp to power them.
Alternitively, you can save up 2-3k and get it all in one hit. Up to you.
Also, hit up Mobile Electronics Australia. There are GREAT deals to be had there, and the equipment is top notch
