this is what I did for the oem stereo and amp I got this off ebay.
for 15 pounds.
then I put the spare blue cable and plugged it into this slot

now my amp comes one with my stereo and off when I turn it off
they sell one for 4 channels as well.
can I say u loose the rear speakers but it sounds much better.
