using external fuses on mono amps
 

Hi guys
I was wondering, if youre usuing a huge mono amp and it calls for external fuses, is there any formula to figure out the correct total size in fuses to use with regards to the power ratings of the amp? I dont have the manual or spec sheet.



I have an external block which can hold like 4 of the small round glass type fuses
like these:

rather than the blade fuses.

Thanks

calculate the amout of amps of the fuses on the amp and thats how much you need as of amp external fuse

no, what im saying is, this mono amp comes with NO built-in fuses. you gotta use external fusing. it has 2 - 0/1 guage positive inputs and 2 - 0/1 guage negative inputs on the amp itself.

ohh in that case i dont know lol never seen one like that before

What is the make and model of the amp? Its RMS wattage capability?

well, i do have some specs from the spec sheet, but nothing about external fuse sizes.

the amp is rated at:

1250RMS x 1 @ 4ohms
2250RMS x 1 @ 2ohms
3450RMS x 1 @ 1 ohm

all at 13.8V

3450w/13.8 = 250

So I'd go with a 300a fuse, just to be safe ;)

thx Jordy!

so must i use a blade type fuse OR for example,4x70A glass fuses?

also...

i got 0/1 guage running to the rear. should i split it into 2- 4guages for both the positive and negative dual-inputs or must i run 2 runs of 0/1 guage in both pos./neg. inputs ??

Get yourself an ANL fuse and holder... like this one from Knukonceptz....

If your system takes dual 1 inputs then run 2 runs of 1/0 from the front to back ;) (so 4 total)

Otherwise you're really only doing 1 run to an amp that takes 2 for input.... right? ;)

what if i split the single 0/1 into 2-4guage ? not any better?

also, my glass fuse holder can use any size fuses and allows 0/1 in TO 0/1 out, so the 0/1 wont be split any if i dont want it to be
