Tweeters being dash speakers I would assume (unless you have component speakers). Are they hooked up to an amp, or are they running off of the speaker outputs on the H.U.? If they are run off of the same amp as the door speakers, I would look at the amp. If they are run off of the H.U., and the door speakers are run off of the amp, II would look at the H.U. How old is the H.U.? Did you buy it new, or used? Do you have a warranty on it? If you do have one, I would call up the manufacturer and describe the problem. If they are run on the amp, I would look at the amp. Make sure all of your speaker connections are tight. And make sure the RCA's are all the way in the jacks and the connection is not sloppy.
