Getting rid of Alternator Whine

RonRizz · 01-05-2014, 04:34 PM

The gain on your amp is used to match input voltage from your source unit. It needs to be set to allow your amplifier to work at its best. If your Source is putting out 4 volts, thats where your amp gain needs to be.
There are a few different methods for setting your gain, The least favorable of which is by ear. Look into setting it with a multimeter, your easiest option.

As per RonRizz you will get the best sound when levels are matched but it sounds like you're in the ballpark. If you are getting enough volume and distortion is low, it may not be worth messing with. Depends on how picky you are.
