Oh nice!~ I think I've kind of changed my mind on the plans I've got. I'll stick to returning the components and getting the crescendo un- 6.5s but, I think I'm just going to completely save until I get my truck and then I'll buy a new amp and sub, as well as tweeters especially based on the truck I have. I'll just be happy with the kenwood tweets, and the Un-6.5 on the 4 channel amp. Running a more powerful speaker on that 4 channel alpine won't harm the speakers or the amp will it? If not I'll just run the tweets and Un 6.5 through the 4 chan and the rears through HU.
