    Hi I tried to fit in my new aftermarket radio using this wire but I still have no speaker/subwoofer sound from the back. I have a 2005 a3 8p 5door 1.6FSI with half amplified rear speakers.
    I believe it is not bose as it does not say it on the doors.
    How is the cable meant to be wired into the stereo. Any diagrams or how to's?

    Any help would be appreciated


    After market stereo: Alpine CDA-137BTi

    if you car has the amp and sub as standard then there is no rear speaker outputs from the factory unit , it will however have low level outputs from the original unit ,these will need modifying slightly so the can be connected to the new head units pre outs.

    what stereo did you previously have ?

    Run the blue wire off the adaptor to ignition 12v. The amp doesn't turn on from normal amp-remote feeds off a head unit, they dont give enough power out for the factory amp to turn on. Once u've done this, fade the sound to the rear until the speakers sound level

    With your cable. Change the fader to about a 1/4 to the back...and should hear music. It's plug and play really.
