so i have done all that i intend to do with my stereo for now:
front: polk db 6501
rear pillar: polk db 5701
sub: polk db 1212
amp: infinity reference series. (300 watts bridged, two channels)
deck: kenwood (can't remember model number) 22 watts RMS 50 peak, two pre-outs, one line in, no usb tho... too much more expensive to get that...
so far everything seems to work great, and sound great, i've been lovin it!
and, it wasn't too expensive, i got all of it in for under 450 (got the amp on craigslist for cheap....)
