Stuff the box with polyfill. Its pillow stuffing. Its at Walmart, just saw it this weekend for $1.99 for 20 ounces. Buy 2 bags, and stuff both boxes with it until it almost touches the subs. The polyfill basically slows down the acoustic wave the sub sends out, making it "think" its really in a bigger box.

how much does it help??? like a lot i think the box is way to small or something. if hte box is small does it cause the sub not to bump????

Well, if the box is much smaller than recommended, its time to make a new box. I have the software that will give me the correct dimensions and specs for a box. I just need you're sub info. That's if you want to make you're own.... You can have Home depot cut the dimensions. Then you screw it together you're self, cut a hole for the sub, and put a terminal at the back. Put in some wires, fill with polyfill, and seal everything really well, you're done.

If this is a new sub it may need more time to break in the suspension. You definitely need to calculate the box you need before you stick a sub in any old box. Also verify that you have the amp wired optimally for the sub you have.

Polyfil will only give you 20% increase in box volume as far as the sub sees it. If you box is 1 Cubic foot, and you need to get to 1.2 that will work. Other wise it is time to rebuild.

yes its a brand new sub and also thanks for all the help. im not 100% sure what the volume of the box is the the guy i bought it from said that it was made for the kicker comp vr 15 inch so thats what i got. its a custom fiber glass box. so i really dont want to get a new box since i paid good money for it. but i guess ill wait it out and try the poly fill.
