Hey guys,

I've just tried to take advantage of the rear speaker outputs on the standard radio unit in my kr42 townace.

The car originally only came with front speakers so there is a plug that does the front speakers and power etc..

On the diagram here on the right hand side where it has KLMNOP it shows the diagram for the rear outputs.

I've wired it up as per these instructions but I'm not getting any output.

Just wondering if there would be something stopping the unit from outputting sound for the rear speakers because it never came standard or perhaps this diagram is just wrong?

Cheers,
Gerald
