Looks good I think. Sound is very underwhelming... pretty bummed at the moment.

is your sub a dvc 2? I have that same amp, it can definitely move that sub. If anything a bit oversize box would allow the sub to move even more.

Yup it sure is. I checked my wires that are going to the amp before I even set the sub in the box just to be sure. And I was sitting at a solid 1.0. 

I thought for sure this thing would move a ton in a box this size. My subsonic is set to 20hz which I know is low but I just wanted to see if the damn tong would get moving. 

Also, I just had dual type r's hooked up to this thing and I was flexing pretty good. I think it's the box. I dunno what else it could be....

What about your gain?

Gain was set with a DD1 like a year ago. I can def get it retuned just to be sure that's not it but it shouldn't be the problem.

What method did you use to set your subsonic and low pass filters? What head unit do you have?

Pioneer head unit. Not sure the model. Never "tuned" my ss or low pass other than by ear.

Do these steps at low/medium volume levels to avoid damaging your speakers.

Turn your subsonic all of the way counter clockwise, turn your low pass all of the way clockwise. Check your head unit's manual for steps on how to set its low pass and high pass filters. Turn them off. Has the output of the sub changed?

Give it a shot here shortly. I'll let you know how it goes

Also, check to make sure the "low" or "sub" setting is set to 0 or higher. If you have to change it, then you will also have to reset your gain. Which pioneer unit do you have?
