They make fuses, or breakers, designed to protect your speakers. I know I’ve seen them in the Parts-Express catalog. Although, it may require some math to decide what size you need to protect your speakers from your amp. If clipping, or just plain amperage, heat the voice coil enough it will trip the breaker, or blow the fuse instead. I had a pair of speakers once that had fuses, I eventually blew them, opened the speaker to discover they existed, and removed them from the circuit. I really didn’t hear any difference whether they were in or out. So adding them shouldn’t hurt your sound quality.
