Hello,
Can anyone help me with an amplifier main connector diagram? My left side door has no sound and I don't want to take the door cards off, I just want to give signal to speakers to see if there is no problem in between.

Thank you,
Edi

Hi,

I am also looking for a wiring diagram.

Got water in the boot, comes in when car parked with front higher than back, but only happens on driver side for some strange reason.

Anyway the water wrecked my amp and I didn't want to pay for a brand new one and couldn't find a z4 one cheap so in the end went for an X3 amp because I was told they were identical.

Turns out they aren't, the Z4 has 5 outputs for the 10 speakers and the X3 amp has only 3 outputs, so my passenger side door speakers don't work, although the sub behind passenger does.

So my plan is to bridge the speaker amp output wires between the driver side door and the passenger side door to get them working. I'm guessing the speakers will only have half the power available but I don't listen to the radio at full blast anyway so that's okay.

Please can someone tell me which wires are for what so that I can cross them to get all speakers working?

Thanks.

I am in the process of replacing the head unit and amplifier (keeping the speakers), and I have got this information regarding wiring in a 10 speaker DSP system:

Left Door BLUE WIRES (white and brown stripes)
Left Mirror YELLOW WIRES (red and brown stripes)
Left Footwell RED WIRES (brown and yellow stripes)

Right Door BLUE WIRES (red and brown stripes)
Right Mirror BLUE WIRES (black and brown stripes)
Right Footwell BLUE WIRES (red and brown stripes)

Left Rear YELLOW WIRES (black and brown stripes)
Right Rear WHITE WIRES (black and brown stripes)

Left Subwoofer BROWN and YELLOW wires
Right Subwoofer BROWN and BLUE wires
