Changing fuse ratings

Suppose I put four 40 amp fuses in instead of the four 30 amp fuses, what do you think?

it will create smoke inside the amp.

magic smoke FTW. when you see it, you know you are getting the most dbs possible

Maybe, but how would you know for sure what amprage the amp can take?

I believe high current is ok if it has a steady flow. ? 2ga to the neg and pos.

Amp never gets hot.

I have never blown a fuse and it is dropped to .5 ohms. My math tells me that at 14.7 V I am dropping about 441 watts through each coil (d2 =x4)=1,764 watts final @ .5ohms.

I am just curiouse if anyone tried that because i was searching around the topic of fuses and noticed that some amps dont have internal-onboard fuses, and rely on in-line fuses. So that is where my question comes from.

This is just hypothetical questions.

If you're not blowing any fuses, then don't bother putting bigger fuses in.

i did this

went from 30s to 40 cuz they started blowing and i couldnt find the problem

You couldnt find the problem before switching them out?

Did switching your fuses help it from blowing them?

I am not. I was just curiose to see what CA.com thought about this.

Putting in bigger fuses doesn't mean your going to gain anything. You fuse the amp for protection, so why change them.

actually I was trying to figure the wattage in relations to the fuse rating and voltage drops. I dont intend to change my fuses.

There wouldn't be any point if it has never blown the 30 amp fuses. The amp can only draw so much current, if you want more power out of the amp you have to upgrade some internal components before you should change the fuses.
