F me, I need answers please...

I believe the purplesyrup guy with the wine barrel had the same issue. He couldn't pop a 100a fuse with a Mmats 4000.1.

Odd...

Might be that the amps have enough capacitance or buffer to prevent a sudden draw on your electrical system causing the fuse to pop.

That's just merely a guess but would need someone with much more knowledge than myself to explain.

The T15K is the only amplifier, that I know of, that actually "stores" energy by means of a large internal capacitance bank of ultracapacitors / supercaps.

The capacitance in all other amplifiers is mainly for filtering, not energy storage.

Here's a spec sheet on an ANL fuse:

Check out the current curves.

The fuses will take ~2X their current rating for a continuous 100 seconds before melting.

Fuses are meant to protect you from very large current spikes (shorts to ground), not necessary just "smaller" increases in current.

So does running a smaller fuse actually hurt voltage or only when it heats up ? My amps recommend 100 amp fuses and i run 80s..what i had ..Whats the downside of running smaller fuses ?

Yes and yes.

Exactly like running smaller power wire from the front to back, it will induce more voltage drop. A fuse is just a chuck of copper, same as your power wire.

When your conductor heats up, the resistance will increase so more voltage drop. Double edged sword.

I doubt you would see any difference in running an 80A fuse.

From the above chart, it showed that an 80A fuse would probably run ~160A for 10 seconds until melting.

Fuses are thermal so it takes a large current to blow them.

If you were to run that 80A fuse at 100A for a matter of hours then it could gradually heat up and eventually melt down but since audio is so dynamic, it has time to cool and therefore it lasts.

There is a lot of different type of fuses. fast acting, time delay, single element fuses and a lot of special fuses made for different applications. like someone said fuses are thermal overload protection only... These fuses are probably time delay, meaning you would have to pull a lot of steady current for a long period of time. If your power is sufficient it will make a huge difference. The fuses are doing there job, if they are not blowing they are happy. 10 years of electrical experience.
