Time to build a new one. Or go with an external port.

you can increase or decrease port length or size. you can also add polyfill to slightly lower tuning or glue in a block of wood to raise tuning. You can add spacers to the sub to slightly increase volume. Thats about it though man.

ok But at the risk of sounding like a noob which ill always be but how do i tune it. See what its tuned at?

I have a 1200 watt 15. 3 cube box now.

You would have to list the speakers used, the box size, the port length for anyone to be able to determine that.

Post the external dimensions of the box, internal dims of the port and the models of sub(s) and amp(s) to see what options you may have.

The amp wouldn't matter, Joe. He asked specifically how to tune the box that's already built.
