Adding sub to Audi concert

[steve094]

Hello I have a standard non Bose Audi concert and I wast to add external active sub I have the live and the ground wired also the speakers to it so there is a steady 12 volts passing through and there is a non amplified bass how do I get the stereo to remote switch the amp which cable would this be?? I tried to use a cable going to the blaupunkt amp in the boot but this doesn't seem to have achieved anything. Please help me. Or ask for any further details.

Try looking on the back of the stereo they usually tell you what the wire harness pins are
Blue - remote turn on etc.

Your best bet is to install a decent speaker to rca adaptor to run the amp. Good quality ones of these have signal sensing and a remote 12v output for amplifier turn on. I regularly use the Audison SLi2. It's about £50. Can find on eBay.
