I have had my BTL for less than 1 year and it is now dead.  I had it powered by a zx2500.1and it  is in a properly sized and tuned box..  NO bass boost, subsonic on, gain 1/2 way up. The spider is ripped a little bit but I can not see any other damage.  IT does smell funny. I am a responsible user and did not abuse the sub whatsoever. I have been installing and using car audio for years,. Does Fi have some kind of warranty, Can I send it back for a recone?  I would appreciate any input. THanks
