u may not be able to use a minifuse as I think 30 is teh highest. Check the box it came in and it should tell you the amperage it draws. Otherwise you'll have to use a voltimeter to measure the amperage output and go the next step up. And inline fuse of a higher grade should help. Take afew mts to visit a local auto-stereo/ audio store and those guys will easily know how to fix. popping 30 amp fuses is odd, that must be some crazy set up. But the store should have what u need and explain where to install along the power line.
