Rubicon Fried

Here we have a soundstream rubicon 1600 that I bought a month ago. Just hooked it up 2 weeks ago. Went on vacation bumped almost the whole way there, hit a pot hole, heard a pop, sub cut out. Fuse in the power wire popped. I replaced the fuse, turned the radio on, and instantly, smoke was coming outta the amp. It had been off for like 36 hours or more before I turned it on.
