I ended up ordering an 'open box special' Stage 1 speaker kit from BSW. They gave me an awesome deal, can't wait to try it out. I did the full-on, everything-must-go stereo replacement on my 325 and I don't want to go through that again. Sounds great (Nak/JL Audio) but there was just too much pulling of panels & carpet & hole drilling to go through again. I'll see how the MB Quarts sound, then think about a sub in the future if I feel the need. I still have delusions of using a DSP box with long excursion 6-1/2" drivers and an aftermarket sub... but it'd probably be cheaper and more effective to use BSW's.
