After nearly having my ears (and speakers) blown out by an errant police officer overmodulating his radio while driving next to me on the freeway, I opted to wrap my audio cables and speaker wires with 3M copper adhesive tape. There spiral wrapped from end to end and the end nearest the signal origination is grounded through a copper braid and ring terminal. This is similar to the RF hardening the military used to do
