I have this woofer connected to my pioneer with the RCA. This A/V receiver was my friends so I know it used to work with his EP175. His sub entered power saving state.

I have put brand new RCA cable to the sub and receiver, but the sub still will not enter sleep.

Any one ever seen this before? The receiver does not has the remote signal capability through 3.5mm to control the state of the sub.

The RCA I am using is a stinger king cable which is all platinum anti-corrosion, multiple direction braided shielding, and screw tightening outside connector. The old RCA was a gold plated Nakamichi, and also did not work.
