Re: Hooking up my crossover power wire.
If your HU has a built in Crossover there is no need for the crossover network, I found that out trying to tune a system that had a CDA-117 and a 2-way Active network, save some headache and ditch the crossover network. The crossovers were built for a time when you had to get really high end HU's to have multiple sets of Pre-outs and built in crossovers.
