Speaker wiring -- 1999.5 A4 Avant

[thejimrose]

i don't.. but you shoudn't really need one. you can use a multimeter to find
the speakers in the plug by setting it to measure ohms, you should see 4o or
so.. you can also use a 9v battery to test leads, the speaker will make
scratchy sounds when you hit it's leads in the plug.

im my a4 the rears used a common ground wire [3 wires in total ran to the
rears]. i ran separate wires since i had the car opened up anyway.. but mine
are in the rear deck.
