THis box is for 2 "S12L7" woofers.

And when I take off one of my woofers, both woofers sounds very good or the sound made by the one of them wich it's in the box, is really good.

this is another tip. thank you.

My friend's got this problem w/ his subs. Two 12 pioneer's in a ported box. One hooked up sounds louder and way better then both playing together. I think it is either the amp or the box. Haven't had time to look at it carefully yet.

P.S. - Check the wiring to see if you have them hooked up both together or if one's hooked up backwards (don't forget how the subs are hooked up inside the box also).

Sounds like somethings outta phase. I would pull the subs outta the box and check, double check and triple check your wiring to be sure all your positives and negatives are going where they are supposed to. Also if you are using terminal cups be sure that the positive and negative wires are running to the positive and negative poles on both sides of the cup.

also try bumping each coil seperatly being that one may be incorect from factory and could cause you to wire out of phase with out knowing so
