Hi guys this z4 still has no working Stereo!!
This was found on this site which will be a massive help

So with that diagram will I have to buy two 3 way crossovers? So I can wire bass mid tweet to each crossover this making speakers work



My problem is I don’t know which wires are direct from head unit in the boot?

Or does anyone have a better solution?

Thankyou guys all much appreciated

These wires are all twisted pairs and a labelled primary colour first second colour is the stripe.

Additional wires are:

The all white wire is switched 12v so good for remote

Don't forget the subwoofers are not a standard impedance, so make sure a replacement amp will drive them.

My Carver DSP amp got wet, but I dried it out and cleaned it, and it's worked fine for 12 months plus.

The likes of ECU testing can probably repair the amp for a fraction of the new price - DON'T use BBA-Reman...

I'd be getting it repaired/swapping for a used one as it's a lot of hassle replacing the Carver DSP with an aftermarket setup, and unless you are spending big £, it probably won't sound as good.

I did read that ohm issue but read still works, head unit has been changed so that is now amplified

Car is to be sold so stereo needs to just be working to a decent standard
