I just got a pair of N800F crossovers for my Valencias (which inexplicably came with N500Gs in them).

The seem to have the following colors of wires:
Red
Green
Black (2)
Yellow
Brown

So I'm guessing that the Red and Green are the + wires for the high pass and low pass, respectively.

How do I know which black wire to use for each? Or does it not matter?

Also, is Yellow the input +, and Brown the input -?

Thanks in advance for the help.

P.S. I'm planning on using either an electronic crossover (current setup) or build a diy crossover - I only bought the N800Fs in case I decide to sell them in (nearly) original condition.
