We no longer warranty our subs. First, we fully test each sub as part of the approval process so we know they work when they leave our facility... So yes, guranteed no DOA! If you get the sub and hook it up in that special way with one voice coil out of phase and cook the coil, even though you cannot smell the coil, you have killed your sub. (I myself have performed this action several times.) Always do a polarity test with 12v power or even a 9v battery to ensure that the cone jumps out. (Out means you have pos to pos and neg to neg, thumbs up. If it jumps inward you have the coils hooked up right you just have the power source, (12v or 9v), hooked up backwards, swich polarity to cure.) If you try and send it back with this, 'defect', you are a douchey dummy and will be treated so because this is not a defect you douchey dummy and should take responsibility for your doucheyness by buying a new one or a recone kit / service.
Lastly, if you are indeed a short sited, little baby consumer that doesn't see the opportunity here and you just want cheap subs for yourself, you can buy some sort of warranty through
eBay. Not good enough?? Go to Best Buy and buy some of their gear that you can blow up and return.
