Stereo Wiring Harness for Z3

[Davros]

There is an American site - bimmerTech which, after you've registered, offers a VIN check service to determine which HK system was fitted to your Z; they may help you identify what speaker kit you have?

Great reply; many thanks. Mine is basic as basic can be, not a high-spec car bar the ashtray(!) but I fear the sound system is also basic - no centre sub woofer, unless I just can't find it, I don't think the speakers are the best they can be either (was there a choice of a HK setup or a more basic system?) and the door tweeters have one small tweeter then a vacant hole alongside under the trim cover. My head unit is a tried and tested Pioneer model that has been in many cars with me, so I suspect the layout of the fitted speakers doesn't provide the best sound. I'll strip them out shortly when fixing the seats and see what can be improved.

My ZED has the basic set up as well where the amplifier was situated behind the passenger foot well speaker. There is a YouTube video on how to remove it and which wires to join after cutting off the plug, its very simple. My head unit now powers all the speakers and the sound is much better as that has a built in amp like so many new units. I did eventually swap all the speakers over for Pioneer which improved the sound even more. They even do a small subwoofer which i fitted to the underside of the passenger footwell.
