Yea I did something wrong. I’m not sure exactly what the bass boost button does but I didn’t notice at all and I was playing them loud. It was a big improvement. Overall it balanced things out. In the front the volume level where it starts to distort was higher. I was able to turn it up louder. As of now I have the fade to the front. So that it doesn’t play sound.

Well conventional wisdom is that you really want everything sounding like it's coming from in front of you and the higher frequencies you play the more directional they are. Consider upgrading your fronts or improving the mounting locations if you need more mid-bass, not trying to add more drivers and play higher frequencies in the trunk.
