A:Answer Hello. Yes - a sub-woofer connects to the pre-out port in the rear panel of the PM8006. Alternatively, if your sub-woofer has speaker inputs, you can connect it to the PM8006 using the Speaker B terminals on the PM8006's rear panel. This would not effect the power delivery of the PM8006 to your main speakers because the sub-woofer is still using it's own built-in amplifier
