What size wire are you running to the fuse holder?

I would think you have one of two problems. Your wiring could be undersized for the current it is carrying, or you could have loose connections in the fuse box.

Feel the wires to see if they are hot.

I would check the power wire for a short to ground, especially where it goes through the fire wall. Or you might have a loose ground connection. I would assume 0 gauge is more than sufficient, unless you are running some super high power amp.

only feel the wire getting warm on my 5000 strand or so 0 gauge wire between the battery(which is under the back seat so no firewall involved) and the fuse holder which is about 2 1/5 feet long none of the other wire is affected and its pretty much a straight forward setup and i've had plenty of extreme setups but never this problem

you could have a short anywhere on the wire to the amp and still see the heat effects at the fuse holder.
is this a new issue or has it done it since installed because i wouldnt think that would be a good location for a battery or something you know is going to make some heat under normal operation

Do you have a good connection on the battery? How do you have the 0 gauge connected to the battery? Pics?

Some fuseholders use rivet style fasteners to connect metal parts together and some are just not pressed adequately. The cure is to solder the parts together if you can get access to that joint but best yet is replace the fuseholder.

OR you may have exceeded the rating on the fuseholder. They have an (often ignored) rating for individual fuses and another rating for the whole device.
