S trange problem...I have an 11 jku with stock infinity system. When I use u connect to listen to slacker or Pandora, I get a raspy, static y sound from the tweeters. I do not notice it at all while listening to the radio. If I turn the treble all the way down, the rasp goes away, but when I get to around negative 4 on the treble it starts to become noticeable again. notsure what is going on but it it's super annoying. Any ideas or suggestions? Am I missing something with the bass, treble, midrange adjustment? Should I just disconnect the tweeters all together? Thanks for the help...

 

I would say its probably just the Bluetooth connection. I have an '12 wrangler and my Bluetooth is raspy as well. Just my thoughts on it.
