I purchased a Pioneer – 8″ 100-Watt Powered Subwoofer SW-8 today from best buy and told them I had just bought a Denon AVR-791, he told me to buy basic red and white cables and plug them into the subwoofer and plug the other end into the any of the ports in the receiver. I can’t get the subwoofer to work and I noticed the receiver doesn’t have an audio. Can anyone help what to do? Or how to fix this up?
