Default amp on mute: power drain

Yesterday while working on the boat around 4 pm, I had the Sirius channel on at normal listening level (25%). I muted the entire system thru the remote while I got a phone call. Got busy and forgot about the system being on mute and went inside. Came out about 10 pm and found it on mute. How much power was I using? Since the amps were not producing music, was the power use as if it was a volume of zero or no music input, or was it using power as if it was playing music at 25%? Another reason to have spare batt power to counter the "idiot" factor......

Default RE: amp on mute: power drain

my guess w/o schematics would be idle consumption at mute. Othewise would require shunting power to resistive load and that is both expensive and generates heat/packaging issues and is not exactly "elegant" engineering., which I would think is the case w caliber gear you have.

i doubt it would drain much, but if you want to know for sure. Get a digital multimeter with an amperage function. disconnect the amp's positive power connection, and place the red lead on the disconnected power wire, and the black lead on the amp's positive terminal. if the amp is drawing anything at mute, your meter will tell you how much.

when that amp is cranking you will probably be pulling anywhere from 30-40 amps from what i metered on my last jl setup that was similar to yours.

edit, dont try to measure the amperage with the amp cranking, your meter probably wont like that many amps running though it
