OK technonerds! The pt100 has a subwoofer out which is a summed left and right channel, but no crossover control on back. It will feed the total signal to the sub. and the woofers in the speakers will be receiving an unfiltered bass which is a strain on both the amp and the left and right speakers. If I feed my power amp to the subwoofer speaker in and feed my main speakers with the speaker outs on the sub will it detract from the overall sound in system. Have an Acoustech H100 sub with speaker level ins and outs. I'm worried the sub amplifier is not so good. Than k y'all!
