You're ears are covered?

Ummm....hmmm.....maybe your box has a massive air leak? Maybe the subs are out of phase with each other?

Is the problem you can't hear any bass in the cabin of the car, or any bass from them period, even if you are standing right next to them?

No, you'd still hear the bass.

My only thoughts are that it's one of the two things I mentioned in my other post.

You have the polarity wrong one one of the subs, double, triple, quadruple check you speaker polarity.

When out of phase, one sub moves opposite of the other sub and cancels out all the bass.

Check you're speaker connection polarity.

One of my MTX's was like that from the factory. You can see the red wire coming from the VC to the black terminal. Took me about 2 hours of looking and going crazy to find that shit. I keept thinking "Black=negative. WTF AM I DOING WRONG!!!"

well Kinda...

The red wire(+) coming from the vooice coil has the black terminal(-) on it, and vice versa. So depending on how I have to wire it, I might have to.

Just double check the wire not the terminal and make sure thats not whats happening to you.
