Installing a dedicated AC line
I'd like to plug my amplifier into an outlet with a dedicated AC line back to the breaker box. Any suggestions on which Romex line to use or other steps to reduce noise and improve isolation? What can I do between the box and the outlet to improve my system? I've searched some DIY forums without much help. Thanks.
