Louder means higher voltage. You might try it. It works for me when I (re) solder terminations, but the break-in only takes a 1/2 hour of medium volume playing.
One European cable manufacturer "breaks in" his UNterminated wires by using them as a main cable for a few hours (on a lamp bulb if I'm not mistaken). That's 230V, 50Hz AC.
DON'T DO THIS unless you're an electrician!
Just mentioned it to give an idea of what crazy things we people will do. A cable cooker is more benign & much more expensive:)
