I don't believe the warranty is transferrable but when i did call up to them, since i bought one from sundownz a few weeks back, he said they're amps are made so that you wont need to use a warranty, but if you send it back and something is wrong with the unit they would fix or replace it, or if its from abuse they will give a good rate to repair. You may want to call them up direct and find out for yourself 417-859-6025 9-6 cst
