I have a self powered subwoofer and I always keep forgetting to turn it off,

is this normal when you leave it on 24/7? I know you people probably answered

most of this type of questions, but search really isn't working for me right now.

They're usually powered subs. Any equipment that turns on when it detects a signal.

All the subwoofers I have are on AUTO ON.But leaving a sub constantly on should be fine if the interconnect from the pre/pro to your sub(s) does not pick up any parasitic information. If there is any hum,any noise set it to auto on.

There is no Auto ON. There is a button and the choices are ON and OFF.

It's a powered subwoofer and it's connected via RCA plugs, not wires.

Is your sub amplifier class D or class AB? Easy to tell by looking at the back; if there is a heatsink it is likely AB, no heat sink and you got a class D. Leaving an AB amplifier on will draw some power even at idle but only a few watts. Leaving a class D amplifier on will draw next to nothing. This is only a consideration if you're concerned about electric usage though; it won't hurt the amplifier.


I leave mine on all the time with no problems. If you're not comfortable with this, shut it off.
