So despite what some ppl say. I wired up RCA's to the front tweeter amps...and you are all right...an aftermarket unit does over power them...easily...have to turn the system flat to not sound like they are Blowin up. Has anyone tried swapping the output of the tweeters to the door speakers, and running the regular deck power to the tweeters unamplified?. And or/used aftermarket tweeters with the factory amp?. Curious I am
