Re: Idle Power


It depends on the design of the power circuit. Class "A" and "AB" amps draw almost as much power at idle as they do running full out as the design is such that the entire circuit is active all the time.
Some subs turn themselves off if they dont receive a signal
The best option is to turn them off if not in use by using a switched circuit.
