aftermarket head unit on 2000 a6 avant but I still want to use audi subwoofer
I have a 2000 audi a6 avant 1.8t to sell and I want to take out the concert stereo and put in a Kenwood cd player I have knocking around.
I can happily run the door speakers off the head unit but it would be nice to keep the factory audi amplified subwoofer in the boot going as it's there......
How do I go about wiring this up with the sub still working? shall I keep the rear door speakers on the audi amp or from the head unit?
