I went with 6x8 3-ways in all 4 speaker locations (Pioneer, I think), a sub in the trunk, 2 amps (they're getting old and need replacement) and a Kenwood Excelon head unit (KDC-X702) because it can read FLAC files directly off of flash drives (my other beater car has an older Kenwood that didn't so I use the AUX in with a media player). Music sounds great, volume around 20 or 21 is loud enough for comfortable listening without going deaf. I like the 3-ways because I don't want speakers having to do too much each.Ok guys, get me off the fence. Amp wont get here till wednesday anyway (i work wed-sat nights). Should i return the 5.25" rounds and get 6x9? 5.25 F and 6x8R or 6x8F and 6x9 R. Im more of a midrange guy, i like full cabin sound, not just the front. I generally turn down trebel on most radios, my ears are pretty sensitive in the high ranges.
