I am wondering if the ML amplifier amp fan always runs or only when it is needed. Now the that the weather is warmer I am starting to hear what I think is the ML amp fan from behind the rear sears run. I am not sure if this amp is always running or only when the system is on and when it's hot.

I typically use the cassette tape for audio input and even when I am not listening to anything I still let the "tape" spin... this probably keeps the ML amp turned on needlessly... now I am thinking this is probably a bad idea, it's probably best to turn off the entire system when I am not actively listening to anything. The only thing is I typically keep the audio system cover closed to hide the embarrassing tape deck from view and use the steering wheel controls for everything... but I don't know of a way to turn the audio system off from the steering wheel controls (without opening up the cover).

Just sharing some thoughts...

 

Press and hold the Mode button on the steering wheel. The stereo will beep, and shut off. A short press of the Mode button turns it back on.
