hi all could do with some advice please

ok in my a4 sline the speakers only work in the front,the amp clicks on in the boot but no sub and nothing in the back doors,it came with a parrot bluetooth phone and im wondering if this has screwed it up,i had to re connect it at the back of the stereo as who had ever fitted it had put a screw in the back connecting block to hold the wire it in place,bit of a bodge,so this is my first problem,not sure how it runs do the rear doors run off the stereo and only the sub run off the amp or does the amp run the back door speakers and the sub?
any help with this would be appreciated

Cheers

Leon

 

Your front doors are speaker out.

Your rear doors and subs are all amplified, and they run off of a low level imput (RCA wire).

I suggest looking at this thread:
