Find out your model of Head Unit, do a google search for the pre out
voltage. If you didn't spend too much cash on it, it's probably 2v. Set
your amp to 2V or greater, your sound will be VERY VERY low.. if you h/u is
2V or less.. when you flip it to 2V or less, you'll find your music much
louder, if your h/u is 2V or less. I'd check your head unit specs just to be
sure. I know i've done it on my soundstream and it hasn't affected
anything.

Never heard of a "push-button" sensitivity selector on an amp. Weird.

Anyway, I'm assuming that if your head unit output voltage is less than 2
volts, then you should choose the 100mV-2V setting. More than 2V and
choose the 2V-8V one. What if you're amp is 2V? I suspect that either
setting won't damage anything, but it will affect how much you have to
turn the volume up on your HU to get a desired volume.


No, I've never heard of a push button sensitivity knob either. Usually
(like on my SS amp for instance), there will be a switch marked
100mV-2V/2V-8V and that will determine the range of your sensitivity
dial. This is obviously what that is, just done as a push-button thing.

I would suspect it's intended as a line/speaker toggle...
