I have a sony surround sound receiver and it inly has one jack for subwoofer and my klh powered sub has 4 jacks in and out. How do I get this thing working?
If it does not have an RCA signal port, it is an unpowered sub, and you power it with the L & R speaker outputs from your receiver, and run the outputs from the sub back to the L & R speakers.
Please also confirm that the receiver can provide the minimum power necessary to drive the subwoofer.
