    Wiring premium tweeters

    I'm installing the front premium tweeter pods and midranges into a '91 318is that came with the non-premium system. I'm a bit confused as to how the tweeter wires connect to the midrange. I pulled the triangular covers off the doors and found the tweeter wires, and used my multimeter to confirm the wires down by the midrange. However, I can't figure out how to attach the tweeter wires to the midrange. In the pic below, I've got the wiring from the head unit attached to the spade connectors on opposite sides of the speaker, and the two wires from the tweeter marked with tape. Wire #1 is a spade connector, but wire #2 has a blue housing with a pin on the inside. I thought I'd cut off the blue connector and attach a spade connector, but there is only one spade terminal open (next to the crossover on the right). The spade connector on the opposite side of the speaker has a wire soldered through it, blocking access to any connector. Do I solder to this connector?
    Thanks for any suggestions.

    The tweeter wires are gray/green and gray/yellow...#2 there is hard to tell if it is gray/yellow, but the connector looks correct.

    Blue/white on that speaker is negative. Connect the gray/yellow ("gelb" is yellow BTW) to the same terminal to provide speaker negative to the tweeter.

    Personally, since I have easy access to 1/8" female spade connectors, I just cut it off and put both wires in one terminal...but that size typically is a bitch to find. However you do it, both wires go to the same terminal of that speaker.

    Your gray/green (#1) goes to the remaining speaker terminal...look closely, it is nothing but the capacitors output...oh, and note the 3 sizes of terminals used...smallest is almost always negative in all car audio speakers BTW.

    Now go kick its ass!

      Hi Luke,

      Thanks for the clarification. I didn't have any spade connectors that small, so I used a butt connector to join the ground wires from the tweeter and from the head unit to the one spade connector on the mid-range, and doubled back the wire on the single wire side to fit the connector. Here's a pic of the speaker hooked up for a test, prior to covering the splice with heat-shrink tubing. The only problem is that one of the mid-ranges was DOA. I got no sound out of the mid-range on one side, but I was getting sound out the tweeter, so I'm confident that the speaker is getting signal (plus the junk speaker I just removed was working). I pulled the speaker and tested it with a 9-volt battery, and while the cone moved on a good speaker I had, the faulty mid-range did nothing. Is there anything else I can test on the speaker, or is it time for me to get another mid-range?

          Thanks, I may take you up on your speaker offer. But first I'll check with the fellow that sold me the speakers and see if he's got a backup.
