    Finally got round to fitting some new component speakers today on the passenger side as the OEM Harmon Kardon one had blown by the sounds of it. I do plan to do the same to the drivers side but waiting on a replacement door brake.

    I have them all fitted and wired to the crossover, but when looking at the OEM wiring I see theres the blue/brown (-) and the blue/red (+) wiring for the woofer, but theres also 4no. other cables that went to the tweeter (which I assume had the crossover built in) Off the top of my head there was a solid green, and maybe a green/white and the 2 others.

    For now I just left the OEM tweeter wires unplugged and wired the new crossover straight to the woofer OEM wiring.

    This obviously isn't right, as the tweeter won't work because the headunit will be sending the frequency to the tweeter wires which aren't connected.

    Can you advise what I can do with these 4 wires? I assume 2 are + and 2 are - , do you know which is which?

    I think then i'll just have to wire it all to the input + and - ports on the new crossover, and then that'll feed to the right woofer/tweeter dependant on the frequency received - right?

    If that's right, I just need a diagram as such of where these 4 wires.

    Solid green? That sounds familiar...it's for the mid range in the door which is green for +ve and blue/green for -ve.

    Of the four wires, two were twisted together and the other two twisted together.

    I only looked at one "twisted set" so to speak, and I believe off the top of my head one was solid green twisted with a green/white.

    I didn't look at the other twisted pair, but I assume in each "twist" there's a + and - so i'll have to split them.

    So from Neals post above, solid green is positive, blue/green negative, any ideas on the other two?

    Or Neal, do you mean the green "twisted pair" will be both positive, and the other two wires I didn't look at will be negative?

    Give me the colours of all the pairs of twisted wires that you are unsure of and I will find out for you

    The wires I'm referring to are those in this picture.

    Theres a black and blue paired with a brown and blue cable, both going to the connector which I noticed today has AMP written across the two ports.

    Then theres a solid green paired with blue and green cable, both going to the connecter which has BMW written across the two ports.

    Blue/Black (+ve) and Blue/Brown (-ve) comes from the amp and connects to right front tweeter. Green (+ve) and Blue/Green (-ve) comes from the amp and connects to the front mid-range speaker.
