I only have this problem when I turn the stock radio to satellite. If i do aux, cd, or fm radio then all of the speakers play. But when I switch to sat i only hear it coming out of the left (driver's) side speakers. So when in sat mode the right side both front and rear don't play any music. Any ideas?

 

Well my guess would be wiring - specifically the wires from the sat radio receiver to the HU since everything else is fine. You can swap the "PLUG" or something maybe? GL

 

ive seen that problem when the antenna starts going bad. its weird and seems like they have nothing to do with eachother, but if you try swapping the anetenna, that might work

 

well i tried wiggling around in the wires and unplugging and plugging everything back in and that seems to not help anything. I haven't tried the antenna though... i get poor reception all the time, i have glass mount antenna but Its brand new i wouldn't think its going bad. If i find someone with an antenna i'll have to try that out though.
