Linear Voltage Output of Headunit?

[Eggman]

All - I am interested in getting the Pioneer Premier DEH-P860MP. One reason is the nice 6.5V outs. However, a friend of mine cautioned me to make sure that it is a linear 6.5V and not "low voltage at low volume" and increasing from there.

Is this the case with this unit?
Is it a true 6.5V across the volume range, or some other type of scale?
(example: 2V at 1/3 volume; 4V at 1/2 volume; etc....or 6.5V at all volumes)?

This is quite concerning to me. Thanks in advance for your help to a newb.

Maybe a MAX rating. Prolly like 4v rms. Dunno, it may do 6.5...?

Pay no attention to the man behind the curtain.... or your friend.

6.5 volt preouts means they put out 6.5 volts at full volume. Zero volts at zero volume. They change at a logarithmic rate (NOT linearly) in between. Volume controls are logarithmic, because your ears are logarithmic.

It's not something you need to concern yourself about.

Your friend sounds rather confused. Maylar hit the nail on the head (as always). Turn down the volume, and you'll get less voltage output.
