    is the box ported or sealed?
    are the positive and negative wire hooked up correctly?

    cvr's come in dual 4 or dual 2. if you have it wired like that and its a dual 4 (which most shops sell the general user) you will see 8ohm. this will hurt nothing but it will also not let your amp perform to its peak.

    please answer what box type you have also.

    2 cubes sealed is most likely your issue. that is entirely way to much sealed volume for that sub. throw a port in the box a nice 3" tube about 12" long would be perfect. should solve your issue. if it doesn't then you got more issues then i can see from here.

    i just looked over the specs again. i must have misread the first go. 1 cube sealed to 1.25 would be prime. 1.75 to 2.5 ported is prime also. something is wrong else where. the box should be ported if its up at 2 cubes but really shouldn't be doing the no sound thing.

    those mesurements are roughly 1.91 cu ft. port displacement will be rougly .05. this brings the box to about 1.86. that is a really fair size. i don't know what would be causing the issue after you port it.

    could the voice coil on the sub be on the way out? i assume your ground is good cause you said it has sound but not alot. is the gain on the amp tuned properly?

    if the VC was going it would be one of two things. gone or noisy. if the spider or motor was weak it would most likely just bottom out from the weight of the woofer.

    im willing to bet its a phasing issue (issue with polarity). Neuman is right in the sense that the box should be ported at that size, but even if it remains sealed, it should still play well just at a horrible bandwidth.lol. i'd pull the sub and recheck the wiring. make sure you have it wired correctly. if its a D4 sub, you can only wire to 2 or 8 ohm, so make sure thats what you intended. also, check ur gain as mentioned before, and whatever you do, do NOT turn ANY bass boost features on.
