No sound from rear channels...HELP!!!

[steelbluesrt8]

I've been scratching my head with this for a while and I can't seem to figure it out. In the morning, when it's below 60 degrees, the rear speakers don't work at all. After about 20 minutes it just comes on. I've got the stock 6-disc NAV (REC?), JBL 6x9's, and a kicker 10 tapped off the RR speaker with an amp. All connections seem good (did a wiggle test), and I'm stumped. Oh, and it's a 05 Mag RT. HELP!!!

if you have the BA system-its commen for the 05-06s to go out like that. theres a tsb for a reflash for the rear channels. my charger did this from day one. i didnt have it reflashed since i re worked the entire system.

Really?!? Man, I hate taking my car in to the dealership. Maybe it's time for a new head unit...anyone recommend a new NAV/DVD for under a grand with steering wheel controls and Blutooth?

I had the same issue, reflash did not work. I bought the upgraded Mopar Kicker Amp and it cleared it up.
