Well i just got the car not to long ago.. and im looking to put in my old sound system from my civic.. I was wondering.. how to route the power wire from the battery to the back and how to get it through the firewall?

Quick responses are greatly appreciated! thank you very much.

 

what year/engine?

 

its the 98 a4 quattro. not sure on the engine.

give that a try. its for adding a sub/amp to a bose system but same idea for running the power.

 

you dont know what engine your new car has ?

v6 = 2.8
4cyl turbo = 1.8t

that should help

 

^oh i thought he meant engine code.. but i have the 1.8t.

 

there's a hole under the ECU box. run the wire through there and under that plastic piece you see when you open the door. keep going past the B pillar and eventually you'll end up in the trunk. if you don't have a bose system your work will be easy lol. are you also putting in a different headunit? if so, there's something about the k line that you have to wire correctly or your car won't scan properly with vag com.

 

i got my headunit all wired.. my rears are amped but not the fronts.. no so need to run the rem wire :-) guy at car shop hooked me up with how to wire it all!

and with the power wire the hole is the ecu is very very convienent.

 

K line? Never heard of that... what does it do and what problems will it cause when you try and scan your car?

I don't know the ins and outs of the K wire, but I've read of it. My 99 2.8 doesn't have it that I know of, or if it did, I didn't have any problems installing my system. Since it's been in, I've had no issues with the stereo and no issues when running vagcom on the car. I remember reading that not all the cars had it, so either I don't, or I do and didn't know it, and just happened to do by chance whatever it is that I was supposed to do.
