Yeah it's quite a bit louder with just one sub playing. All that mess I was talking in my earlier posts was all just a very confusing way of saying just one of my subs was playing. I just wasn't sure why it was louder. It sucks not knowing anything. Anyways, the box gives .75 cuft per chamber and the subs call for .5-.8. I would love to take it to a professional but I don't have the money for it guys. Dare I ask if the amp is underpowering the two subs but gives the right amount of power to just one?

Do you have an ohm meter?

If you do not have an ohm meter, I am surprized that nobody has suggested connecting one voice coil at a time.

I do not have an ohm meter fellas. What would connecting one voice coil at a time do for me?

It will tell you whether or not all of your voice coils are in working order. If you have one open voice coil on each woofer, that would explain why the woofers work when you parallel the coils and then wire the woofers in series.

Ok so I just run the wires from one voice coil to to that sub's terminal and then from the terminal to the amp and the sub should play? Then do this with all the voice coils? What if one or more of them doesn't work? Would that explain why they won't work with the voice coils wired in a series?

also, why would one sub be louder than two? It is a very noticable difference.

when both subs are playing, are they moving a lot? Or do they barely move?

If they are moving a lot, and are not making much bass, you have one of them wired out of phase. Try reversing the positive and negative wires going to only one of the speakers.

that link just sent me to the page the posts were on. Did I ask a stupid question or something? I'm just making sure I understand.

they move a lot and it gets loud but then again i'm not sure what they really should sound like. I wouldn't say the two of them move as much as the one does by itself.
