Amps without fuses

Why do some amps have no fuses? I opened up a crossfire monoblock just to be sure and didn't see ANYTHING, Am i just missing something? I saw the post about the JL amp and internal circuit breakers, do they all do that (the ones without the fuses)?

well i an old crossfire 1000d monoblock (the old white series color not silver) and the manual says it has a 120amp breaker in side but u have to the remote wire over to reset it i dont know how the new crossfires are but check out their website and u'll find older and newer model instructions and if u call or email the tech support their really good about getting back to you so try that hope that helps93 diamante
