fuse block melting

Just a suggestion, see what size (amperage) fuses are in the two amplifiers. I would use the same size in my "under-hood" fuse holder."That'll get ya 10 in Leavenworth,11 in Twelveworth, or 5 & 10 in Woolworth". Groucho Marx                                                      

this is a 200A circuit breaker i have, but i dont have enough current draw to justify using it.

ok i checked the amps they are both kenwood excelons and they have 3 25amp fuses in each amp so 150 amps total. so what should i get for a fuse system? 150 or higher?

A 150 amp fuse is MORE than you will ever need.... but fine none the less.

really? what do you recommend then ?

you going to need to switch out to 4 gauge. With your total current draw you need it. And go with a 150 amp ANL fuse.

yeah, the total fuse rating is not the constant current draw. maybe 120A but not 150A. if the current was maxed out all the time, your fuses on the amp would blow constantly. the fuses on the amp are a last line of defense to protect your amp and the current draw isn't ever supposed to get that high so estimate a little bit less and that is your usual current draw. but still, you should have close to a 150A main fuse at the battery. i dont like glass fuses because they might not blow all of the way and just keep a bad connection instead of blowing apart, thus making more heat, but almost any other fuse that is rate for 150A is better. ANL or MAXI fuses are better but a circuit breaker is best, but way more expensive. i got lucky and got a 200A circuit breaker for free but they are normally around $60, maybe.
