thats the component setup ive got all around (polkDB6501). they sound great, if not maybe a bit heavy on the highs to be honest. ive got all 4 of them running off the head unit, and im betting if i put an amp to them, it would boost up the mids & lows enough to balance everything out or if nothing else, provide some more adjustment. as for the tweeters with this set in particular, while i was able to make them fit, its rediculously close... best case scenario, the brushed aluminum bit of the tweeters bezal will be just slightly under the door panel like mine are....
