I have 2 12" p5's, and I was messing around with my loudness option on my deck, do most people who have this option usually use it? I know I dont, Im just wondering cuz I wanna see how loud I can get these things going.
All the loudness option does is boost certain frequency's at low levels. When you turn your headunit up, the higher the volume the less the loudness option does. They use it to even out the volume of very high and very low fequency's, since they normally sound quieter at lower volumes.
