I had the right channel on my tweeter amp go out comnpletly in my 04, try wiring the tweeters together on teh good channel to see if that improves it (just watch your ohm load you want 8 not 2)

 

update
Some CD's it sounds fine. if i listen to ACDC on it theres no noticable distortion. But if i play State Radio or Dispatch... it gets all whacked out. This doesnt make much sense to me, as neither is really loud... its just reggaeish acoustic rock.

 

It's probably your poor selection of music [sm=smiley20.gif]

 

lol... i used 2 listen 2 thursday but ive lightened up! u can too with a little work lol . anyways, does that rule out a speaker issue and shift things to the amp?
