Biggest issue you face if you want a top end system is the lack of standard speaker hole space. Your really limited to fitting high end speakers in the stock holes which you basically have to weigh up the cost to sound improvement.
My biggest gripe is the limited tuning options with the standard system - you'd have to fit an aftermarket processor to do some serious tuning and that comes with big $$ once again.
You can always basic tune with amps however, you mentioned you didn't want to change amps so that once again limits your options....
...actually quite happy and expected to put an AMP in. The "no amp" was reference to the fact the Australian base sound system doesn't include an amp (afaik) compared with the US which does.
Do the factory upgraded systems, with more speakers, have different door panels to accomodate the extra speakers? If so, surely the door panels are just cut-outs and thus there should still be room for the new speakers? The A-Panel ones would be a different story I presume...
