Hey! I was hoping someone could potentially give me a straight answer. I have an outdated pair of 2.1 speakers from creative that come with a mighty powerful subsoofer. I was wondering if there is anyway to connect the sub to my Yamaha V-371 AV receiver. On the back of the sub there are only two inputs, left and right speakers for the above 2 speakers. Is there anything I can do to use this as a dedicated subwoofer?
