I bought a house that is pre-wired in wall for a 5.1 system. There is a wall plate behind the receiver and corresponding wall plates for each speaker including the sub.
My receiver, Onkyo TX-SR703 only has an LFE output for the sub and my sub, DefTech Prosub100, has both high level speaker connects and LFE jack inputs.
How do I connect the LFE out from the receiver 1. to the wall plate and 2. from the component wall plate to the sub?
