I have the Empeg installed, 2 channel amp in the boot, all wiring looks ok to me.

Sadly no sound from the door speakers.

Hooking a speaker up direct to the amp works ok.

Pulling the door panel and hooking a speaker up to the wiring does not work.

So between the amp in the boot and the door speakers I have a problem.

I think its because the factory BOSE system has a small amp somewhere - anyone come across this?

Have you seen this page:

Thanks Andy, just the information I needed.

I'm now struggling to find a UK supplier for what I need to connect to the BOSE amp - think I need an adapter to go from Un-Bal RCA signal to Bal RCA signal, I also read something about Differential Signal???

http://www.autoleads.co.uk/ would seem like the most likely, via Halfords or Motorworld.

You could also try asking here:

- MX5 owners club BBS http://www.mx5oc.co.uk/mx5forum/default.asp

Thanks again Andy - I posted to an MX5 BBS but didn't get much help.

Don't think its as simple as a wiring adapter, will try a car audio shop tomorrow.

Looking like I need something like the Vendetta II listed here:
