^^^ gotcha, thx for the quick response
you can't run parallels or fusion on PPC machines
yeah you may have been thinking about virtual PC for running windows on PPC macs. the reason parallels and fusion only run on intel macs is because they are simply virtual machines not emulators. Virtual PC (which only runs on PPC macs) on the other hand will translate the x86 instructions to PPC ones which is extremely slow. Best to just get an intel one and boot windows natively unless you want to use a Mac FE.
isn't there a way for me just to wire the speakers to the headunit and also have great sound quality from the aux or an alternative from the carputer?
As long as you don't pick up any ground loops or other noise it should sound pretty good. And ultimately if it sounds good to you that's all that really matters.
