Help replacing front speakers

I am doing my front speaker replacement today, and just got the driver door off. However, I'm unsure of which wires I should be hooking up to my crossover. I see a yellow and a black wire running to the woofer. I see a yellow, a black, a pink, and a purple running to the tweeter. What should be the input + and - for the crossover? What should I be doing with the leftover wires?

thanks in advance!

 

Thanks. Does that mean I should use the pink and purple wires as the input for the crossover, and the yellow and black wires at the tweeter (which also there are a pair of goign to the woofer) should be connected to the woofer output section of the crossover? So basically, the yellow and black wires are only going between the woofer and tweeter?

thanks!

 

Thanks for all the advice guys. Yes I do have the non-JBL version, and I was redoing the front speakers.

I ended up plugging the pink and purple wires into the input of the crossover, then ran a couple new wires to the tweeter, and connected the yellow/black wires to the woofer output section of the crossover. It does appear that the yellow/black (on the drivers side) are merely running between the tweeter and woofer, so that worked great.

On the passenger side, I had 2 sets of green/blue wires. I was able to differentiate between them because one set (the set running between the woofer and tweeter) had a gold dot marked every so often. The other pair had a greenish dot periodically (these dots appeared to be applied with a marker). So, I connected the green dot wires to the input section of the crossover, the gold dot to the woofer output, and new wires for the tweeter.

It all seems to work great... except... I can hear a very faint humming noise even when the radio is turned off (but the car is on). This is most noticable from the tweeter, and is barely audible but definitely there. I can hear the hum on both sets of speakers... is this common? It is quiet enough that the noise could have been there before I set up the speakers and I probably wouldn't have noticed it, but of course I have to wonder if it was something I did to cause it. Ideas?

Thanks!
