The rate of breakin is accelerated by higher power levels, but if that's not practical then just play the rig all day with a tuner source (or CD on repeat) when you're gone to work. You can temporarily wire the speakers out of phase & then place them facing each other to dim some of the racket.
Don't run any AC line voltage through a networked cable or even use a Duotech enhancer; the DC component will burn up the networks.
Expect reasonable results within 100 hours & completion around 200+ hours.
