Plainly put, these speakers are vastly superior to most if not all 6x8's out there. If you drive a Ford, you need to buy these right now! I had the Infinity 6820's front and back and they were ok, didn't hold bass at all, could never really find the sweet spot. My setup consists of modest gear, and Alpine head unit, Alpine KTP 445 amp, a 500 watt Kicker amp with 2 MTX 10" (avoid this amp at all costs) Just running the 6x8's off the alpine KTP amp sounds better than I had imagined, the highs are crisp, mids and bass are adequate, you won't win any awards but if you want good sounds for not a lot of money this is an option. I will only buy Pioneer speakers from now on, until somebody proves otherwise I know what a pain searching for the right setup can be, so I hope this helps, and no, you still can't guard me.......&1 "
