how do you hook up a surround sound system??? j/k need a little more info is the sub dvc(dual voice coil) if so or not what ohm res. is the speaker and is it the old punch 40?
is it the old punch 40 like Joseph said? If it is they did not come with built in x-over's so I hope you were planning on using one. As for monoing that amp go left neg to right pos. That is a vey nice amp if it is the old one
