Blown MM100

Systems

I purchased a MM100 to go into a Volkswagon Beetle Thunderform(manufactured by MTX - like a Qform) and had some difficulty installing it due to the magnet cover on the sub (an unusually large diameter). Well, I got it installed ok with the help of some professional installers at circuit city. Then I went ahead myself and made a dummy move: I bridged the rear two channels of my MTX 6304 (60x4 amp) and tried using that to power my sub. Now, I think it's blown. A measurement of resisance with a voltimeter showed there was now no connection in the sub. Is it fixable or just a throw away? Was the cause too little juice?
