    Guys, a friend of mine (who does have issues posting himself on this forum) does have the following issues after installing the RNS-E PU in his (US) 2010 A3:

    "I do have some feedback coming from the two rear speakers with the ignition off and once the engine is started, I get alternator noise. I figure this is a grounding issue? Also, I notices that my subwoofer isn't working."


    Radio before swap: Concert

    does not have Bose
    does have the multifunction steering wheel
    does have Bluetooth
    does have an auxiliary jack in the center console
    does not have a cd changer

    can you guys help him?

    Has he got an aftermarket amp for the rear speakers or the Audi OE amp?

    Interference such as this is common with an aftermarket amp but very rare with an OE amp - because aftermarket amps tend to use the local ground reference rather than the ground reference from the head unit.
