How to Hook Up a Subwoofer to a Rear Speaker?
Subwoofers are low-frequency effects speakers that produce bass. Many subs are equipped with terminal connections for hooking up additional speakers, typically smaller satellite channels such as rear speakers. The setup uses the subwoofer's crossover control to send audio signals above a certain frequency to the connected speaker; signals below that frequency setting are sent to the subwoofer for producing bass. Standard speaker wire can be used to hook up the rear speaker to the sub.
