quick meca fuse question


Recommended Posts

As the title states, I want to know if you can change - say a 40 amp factory fuse to a 30 amp. After I did this swap twice, it'd make me a little bigger fish in a smaller pond. It's a temporary set up, but I want to to go get my feet wet. Thanks for the info, W

{(Total Amperage of In-line Fusing X 10) + Woofer Cone Surface Area} = Pressure Class #

Please consult Division Rules for complete definitions.

Examples:

30 amps + 2-12 = 526 40 amps + 1-12 = 513 30 amps + 1-15 = 477 50 amps + 1-18 = 754

50 amps + 1-12^2 = 644 50 amps + 2-12 = 726 100 amps + 1-15 = 1177 100 amps + 2-18 = 1509

50 amps + 2-10^2 = 700 100 amps + 2-12 = 1226 200 amps + 2-15 = 2353 200 amps + 2-18 = 2509

50 amps + 3-10 = 736 200 amps + 2-12 = 2226 400 amps + 4-15 = 4707 400 amps + 4-18 = 5018

Thanks for the info Chode, but I've been crunching numbers already. The thing I really need to know is, will the judges frown on me using a smaller than reccomended fuse size? I am wanting to change from my gear's reccomended 80 amps down to 60 amps. I'd be in the low 900's with my 4-10's. The stock pair of 40 amp fuses puts me into the much bigger 1001-2000 class, which would probably put me way out of my element. New build coming soon.

Will they frown on you for running small fuses? No. How do you think some of us are getting big #'s in a low class? :)

Dude i have seen that s10 round town.. Where bouts you stay at?

AS Far as switching fuses it shouldnt be a problem. A guy at the last show switched out 2 40 amps fuses for 2 10s to get into a lower class

Long way past this point, now. It was useful knowledge for me in the past; as it will be useful for someone else in the future, I'd say. Imagine how I felt reading the Meca rules, with my system either bought or sort of in my mind, and thinking I'd be in some mega-class with my little set up!
