I recently bought a Fender PDP Powered Subwoofer, and I cannot get it to play from my Pioneer VSX-D409. I’ve tried everything I can think of, and I cannot get it to play through it. All of my other speakers do. The subwoofer works–as I’ve played music directly and solely through it. Can someone please tell me what I’m doing wrong.
Thank you,
Ben
