Actually there isn't really an 'auto-mode' with Axiom's 500/600 series subwoofers, they are either turned 'on' or 'off' with the power switch and while turned on the amplifiers stay on and do not go into an idle mode like the EP350, EP175 and EP125's do ... the 500/600's stay powered and on the ready at all times.
