hey im reposting this again because i think it got lost in the rest of the posts..

Hey guys, I've looked around threads and googl'ed this a hundred times and i haven't found an answer so i was hoping someone could help. I just recently installed the Pioneer DEH-P4900iB from Crutchfield. ( http://www.crutchfield.com/S-uZnutLK...130DEHP490#Tab ) I also bought the Scosche adapter b/c i have the Bose system in my car. I followed the directions and hooked up the entire thing myself. The stereo turns on, and the power antenna switch i installed myself even works great too, only problem is that everything works except my tweeters on the front pillars. Has anyone else had this problem, or anyone know how to fix this? It would be greatly appreciated.

 

Moved to audio.

 

everything BUT the tweeters? you sure its just the tweeters?

 

Maybe you need to turn up the treble/high adjustment on the HU because you're just not hearing them. I don't see how adding the HU would all of the sudden cause your tweets to not work.
