Help please A6 1,8TS quattro 1998

[fish]

I have no sound at all in the rear door speekers and factory Blaupunkt woofer... I have an after market Pioneer HU and i guess the sub may have its own harness, but the rear doors should have som sound anyway the sound just vanishes if i try fading to the rear... Is the sub on a seperate fuse? If so which one? My handbook is in italian and i cant understand squat.

Cheers

Kris.

If it's a bose system the front and rear + sub is from a 4 channel amp.

Non-bose: Fronts from HU amp, rears+ sub from the amplifier.

My money would be on an unplugged mini-iso on the back of your HU. You could check if your amp is getting power (Red/blue wire) first.

took the HU out, and there is a three coloured plug that is not connected... Mini ISO?

It is a non Bose, doesent say Bose on the speeker mesh anyway. Is there any way of connecting this plug to an aftermarket HU?
