Can someone tell me real quick which wire is positive and which one is negative on the factory plug that connects to the speakers?

Also, where is the crossover located for the tweeter for a non-Rockford fosgate system?

sorry i dont remember what the wires look like, i just ended up using a wiring adapter that came with my speakers, so i didnt pay much attention.

there is no crossover on the non-sss system. its just a resistor on the tweeter that filters out everything but the high frequency.
