I was thinking of running my 4 channel kicker zx850.4 amp to power my comps, I want to run the mids on 2 channels then my highs on the other 2 channels, they each have hi, lo crossover switch on the amp, can i just use the amp crossovers to power my comps, instead of having to also wire my speaker wires to the external crossovers that came with each set? thanks
