my friend and i got the same setup...a 15" rockford fosgate T215D4 and an alpine pdx 1.1000 amp. mine hasnt been installed yet, but the other persons box was finished and the audio store said her sub is broken (burned out voice coil). i dont know what that means. the person she bought it from (on eBay) claimed the sub to be new, so that means that not only is it slightly used, but rather heavily used, enough to burn out a coil right? is that right? can those coils be replaced? the company wants her to get rid of that one and buy a sub from her, saying her t2 is now completely useless. Is this true? we really need some answers on this one!!!

--thanks!!

To my knowledge voice coils can't be replace on any speakers. The voice coil is an internal part on the sub. It's possible it could be a bad sub. You can test the sub with a 9v battery. Connect the 9v battery to the positive and negative terminals, the sub should make a pop sound and you'll see the cone move. That mean you coil is ok. If not your coil is broken. Good luck.

In the picture below, the voice coil is the red/orange coile of wire above the magnet. When the top portion of the speaker is bolted to the motor (magnet assembly, the voice voil moves freely inside the magnetic gap. Inside the top assembly, the voice coil is glued to the spider and cone. The movement of the coil causes the cone to move and produce sound.

The problem with your sub is that you don't have a removable top assembly. For high end subs, you could go back to the manufacturer and have it re-coned. But with RF, they source all of their subs from over seas. It's not worth it to them to fix their parts. Your friend is SOL on this.
