Check out my thread here:

On that page is the pinout (about half way down).

Hi

Do the front twitters are connected in parallel to the front speakers ?

Thanks

From the diagrams I've seen, yes the tweeters are connected in parallel. They have their own high pass crossover built into the tweeter housing.

Do you have a link to the diagrams ? I just bought a C4 VTS in which after market speakers and a hands free system for Cellphone were installed. The problem is that the workshop who did it made a mess with the wires of the connector that is hooked to the RD4 and I want to revert it to the original wiring . Is there any thread that describes this wiring ( from the connector that is hooked to the RD4 )

Thanks

This is one I have, but it's from the C5. I'm not sure if the C4 will be different.
