Well, the factory amp and head unit are gone. I went to PO Performance in Toronto and they dropped in a nice Blaupunkt Munchen. I haven't changed the speakers or added a sub woofer or amp arrangement yet, but just having a decent head unit makes a huge difference.
I played around with the parametric equalizer and now have a very nice warm sound coming from the speakers. All in all, it makes for much nicer drive in the morning.
