How to add a sub woofer to my stereo?
I want to add a sub woofer to my stereo system. The sub woofer is one made from spare parts. It consists of a twelve inch speaker wired directly to binding posts. My problem is that my amplifier only has four binding posts, these are a positive and negative for the left speakers and a positive and negative for the right speakers. I am not sure where to patch in my sub woofer. Thanks for any help
