[QUOTE="ckunke002, post: 7714875, member: 637083"] I know there are other threads on this topic, but I'm reading mixed reports so I want to get this clear. Last week my fuse next to my battery blew, and I didn't know anything about fuses so I just took it into my local car audio shop and let them pick me out the proper fuse. I did a little bit of research after I got home and I'm not sure they gave me what I need. I'm running 4 gauge power wire, and they upgraded my 60 amp fuse that popped with a 200 amp fuse. To my understanding, my 800ish watt system only draws 50/60 amps of current and I can't imagine a 200 amp rated fuse protecting anything when hell breaks loose in my wiring system. How many amps is 4 gauge power wire designed to carry and how does one determine the fuse rating they need? I've read in a few threads that fuse amp rating must be higher than amp's amp consumption (efficiency) but lower than the number of amps that the specific size of wire can safely carry. Is this correct? Thanks anyone and everyone [/QUOTE]
