Isn't 1.1 per sub small?? I know DD recommends even smaller but my calcs show that a bit bigger will give a higher ripple. I will say though that I have not yet built a box for a DD driver.

1.1 IS small...there are 2 boxes here

It is 2.2 net per box/per driver. DD says 1.75 to 2.75 net. Right you are...

DD M4's one on each sub. Got lots of little things to finish up in the car, can't wait to get it rolling. I had some 3512's they did very well, the 9500's are monsters.
