I recently purchased a '03 WRX wagon with the stock stereo. I'm looking to upgrade to some better stereo equipment. I don't need anything crazy, I just want something that sounds somewhat better.
I would also like, if possible, to keep the headunit because I don't want to lose the 6-disc changer.
Should I try installing a subwoofer first? Like the factory sub? What about the upgraded speakers?
Can anyone offer any advice? I don't want to spend a ton of money either...but who does?
