ok, car audio question....
does a stereo amplifier draw any current when the ignition is off? basically, like most properly installed stereos; my head unit "tells" the amps when to turn on. i recently had a draining battery, and i pulled out the inline fuses to my amps and tested the current across the circuit with my anmeter, with the ignition off. i had roughly 19 mA at one amp and 10 at another. i noticed the installer spliced the constant 12V on (yellow) wire to one of the big amp power supply wires too. so i have two variables at the wire moving 19 mA. so far my new optima battery is doing fine but the leaking current may be a problem if i go on vacation and do not drive my truck for awhile. keep in mind, this is for a chevy truck so it doesnt have the sweet melody of a flat six, therefore i need the tunes!
thanks guys.
