d and d is the loudest, and if you can get the power commander set right, its a nice deep sound (its a bit of a raspy sound if you don't). But with it you seem to lose a bit of low end power, and a must is a set of ear plugs, cause you will be going deaf if you don't. Like most things it has its ups and downs.
