Problem with all the TS amps is all of them have shitty wire that is too small for the amp, and that fuseholder will melt off in short order. You don't have to go FR on an amp that small, but some of those big capsule type fuseholders used in car audio work very well. I forget what they hell they're called but they will take up to an 80 or 100 amp fuse and up to 4GA wire.
DC Circuit breakers are nice, too, but I've had them fail "open". And when they do it obviously turns into a huge pain in the ass.... so if you go the circuit breaker route, get a high quality device. A lot of the supposedly high current CBs are junk. Unfortunately its hard to tell whether or not its junk until it fails...
