I just had a few questions about my new A4:

-The rear speakers are not working. I took out the aftermarket head unit to find out its not quite wired right they only used the one harness where the rears dont even go to it. So I bought another wire kit with both harnesses the one is the same but the other has all the speaker positves and what not. what do i do with these??

-The front end is making some noise like something is loose. So i took off the wheels and checked everything out. i shook the tires and what not to look for any movement and found nothing til i was putting the right front tire on when tighting the bolts there was movement can this be a wheel bearing or maybe the hub in general or is there any other common problem up front??

-last the abs goes off when you are almost stopped. there is no abs light what so ever. its almost like a pulsing before you come to a complete stop. i know the rear brakes are metal to metal and im just waiting for parts. could this be some sort of a bad brake warning or is there a bigger problem like a abs control module??

Thanks Alot for any help! KP99AUDIA4

 

i'm having the same abs problem but my brakes are all good. i think i have air in the system that's causing that though. for the front end, it's probably your control arms. as for the rear speakers, you gotta tell us more about the HU you have.

 

The head unit is nothing special just a sony xplod it has all the wires labeled so i just need to know what to do with the wires from the harness i bought on the other plug. there seems to be two sets of positive speaker wires. By the way she a great dancer!

 

The factory sound system uses a separate amp for the rear speakers, it's mounted on the side of the motor assy of the driver's side speaker. To install an aftermarket HU, you'll have to run a new pair of wires back to the rear speakers, or splice into the line-level wires already in place and install an aftermarket amp for the rears.
