I get pounding bass when appropriate and live-sounding voice when that's called for. All without ever having to retune anything.

Me, too, but I will say that it took months of careful tweaking of the EQ and the amp crossovers before it came to that level.

And I still once in a while fiddle with the loudess control. It tends to fluctuate between 3db and ~7db.

3db is when I'm listening alone at levels up close to 0db. 7db is when others are in the car and I have the volume turned way down and I want to hear the bass anyway.
