Hi guys

Need some help!!!

I just bought a new double din aftermarket head unit compelte with DVD player, Nav, Bluetooth etc to replace the Symphony II unit in my Audi S4 (2003 B6)...

However, I've heard on the grapevine that I may have issue with the centre speaker and subwoofer???

I've checked the wiring. On the new head unit it is outputting four channels (L and R front and rear sets). But on the car (Audi) side of the plug it is only taking a singal for the front speakers, so the rear are not intended to be drawn from the original Symphony II unit...

I've heard that there's a seperate amp in the rear that drives the centre (rear???) speakers and also the subwoofer.

If this is the case, from where does it get it's signal? I assume the signal must be sent from the Symphony II head unit???

So if I change head units am I likely to lose the centre (rear?) speakers and subwoofers? If so - that sucks big time!

PLEASE HELP!!!

Many thanks
