Too Much Boom Boom. Not Enough Ting-a-Ling
Ladies and Gentlemen, Summer has officially arrived. And with it comes the warm weather, vacations, and joyful sounds. But as your sitting there enjoying the breeze while waiting for a red light to change, you hear it. The noise we all know and hate. Someone pulls up next to you with their music blaring to the top level and all you hear is distorted bass and his license plate buzzing against his car. Well don't be too angry with the poor guy. He may just be one of the many people who don't know what you know about car audio maintenance.
This poor guy simply forgot to adjust the gain on his amplifier to match the swing on his head unit.
It's a common mistake among most car owners who hook up their rides with top notch sound systems. The get all the bells and whistles and have no idea how to use them.
Think of your gain knob as a volume knob, because technically, that's what it is; a volume knob for your amplifier. Your amplifier and your head unit work together in order to give you more power and volume. But too much gain will give you a distorted sound that is not enjoyable for anyone. The higher the gain number, the less you will have to turn your volume knob on the head unit to get it louder.
Setting your gain at the right level will assure that you will have a pure sound that the musician intended without making it sound like you have killer bees in your trunk trying to get out.
