Subwoofer Fuse and Fuse holder
I have a subwoofer and it blew a fuse. I also managed to crack the holder while installing a new fuse.
I am planning to replace the fuse and install a new fuse holder.
the fuse is 2.5a and 250V.
my question is about the fuse holder. I see that there are different ones that are rated for different amps. some are 10amp and some are 15amp.
I just wanted to confirm that either will be fine to use in this situation. my understanding is that the fuse is the weakest link at 2.5amps so using any fuse holder rated higher than that will work?
thanks in advance

Sub woofers very rarely have fuse protection.
Is the 120v fuse for an amplified sub woofer ?
If it is..... as long as the fuseholder is rated for at least 120vAC.... either amperage is fine.

PJmax: thanks for your reply and comments. I appreciate the clarification on the amperage. Also, the subwoofer is powered with 150 Watts.
manden: the fuse is clear, but I believe it is a slow-blow. I was not aware and I do not think the transparency of the fuse determines this designation?

A ceramic fuse is usually seen in high arc probability/high load locations.
If you have the standard sized glass fuses......
a regular fuse would be an AGC-2.5A.
a slow blow could be a MDL-2.5A.
