Need to know the best way to connect my external subwoofer crossover to my B100 integrated amplifier. My thought is to run the preouts from the B100 to the crossover and than run the hi-pass from the crossover back to the B100 via the main-ins. However, I was told by doing this I would be running the high end through the inferior preamp of the crossover rather than the B100. Any thoughts or advice on how to configure would be greatly appreciated.
