Repeated fuse blowing generally indicates a blown power supply, or blown output stages or both. One thing to do is be sure that you have replaced the fuse with the correct type. A T stamped into the metal of the fuse near the rating, indicates sloblo or Time Lag fuse. A fast blo fuse, may work once, or more times, but will never replace a sloblo fuse in this type if unit. Good Luck, hope this info helps, don't hesitate to hit me back here for more help :)

SOURCE: Fuse keeps blowing?
The fuse is a protective device. Fuses dont blow unless the amp ( in your case ) is drawing too much current. DO NOT put a bigger fuse in. Obviously, there is a problem with the amplifier inside the sub. If the sub is under warranty, send it in for repair to an authorized warranty depot. If not it's not under warranty, then take it to the authorized warranty depot anyway. Why ? because they will have the schematics ( electrical diagrams ) to troubleshoot the unit quickly and it may be a common problem. If it is a common problem, the factory may have released a modification and possibly it could be covered under warranty under a factory 'goodwill' program. Good luck. Rob

More than likely the power supply switching transistors have fried. Also check the large caps in the primary side of the power supply. If you don't know what your are doing do not attempt to fix the power supply.. very dangerous voltages involved !!! Send it to Klipsch for repair or purchase a Bash replacement panel http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-750
