This is a short instructional video on how I install the sensitive shielded input wiring from the RCA jacks to the circuit input in my amps. This might be a little unconventional, but I feel this takes advantage of the shielding on the cable better than using a single conductor with a shield type of wire.
If the amp uses a volume pot: at the back of the pot, connect the shield of the wire from the amp to the pot, to the shield of the wire from the pot to the RCA jack. This way, on both wire sections, the shield is grounded to the amp star ground point.
