as I've mentioned before, don't throw a ton of power at them. 20-30watts is plenty. also might need to EQ them down a fuzz at 10/12.5Khz depending upon power level and music you mostly play.
I just did a 5hr round trip last weekend for Regionals and played the AQ's and 6.5's in the doors the entire time. VERY happy with that set up for daily listening and they can get stupid loud when needed.
They really can sound very good for all types of music if set up properly.
