Thanks for your help Zilch.
I attached one photo, because the crossover has four cutted wires: one yellow and one naked in the upper conector, and two yellow wires in the lower conector.
I see in other thread that the upper yellow wire is the + and the lower yellow/black is the - for the tweeter. Thats right?
But I don't know what is the upper naked and the yellow lower-right wires. Can you help me?
In resume: the red and black wires are the input from amp, the green and black are the output for the woofer, the white and black for the middle and the yellow and yellow/black for the tweeter O.K.?
Thanks for all.
