You don’t exceed the fuse box rating in the truck the same way you don’t do it in your house. There are enough outlets and circuits to plug in more devices than your house’s main panel is capable of supplying. You simply don’t turn them all on at the same time. If you did the main breaker would trip and the entire house goes dead. But it still doesn’t burn to the ground because the main breaker is sized to the main panel. It doesn’t matter that your 100A panel with its 100A main breaker has 6-20A breakers, 6-15A breakers, and paired 30-A breakers for an oven or dryer, they aren’t all on at the same time. If they are then you need a bigger panel, or in the case of our trucks an additional one, which is what I suggested.
If you have a just a few high drain devices then consider separating them from the panel with their own fuse/breaker and/or high current relays if you want them switched.
You need to figure out what the current draw of your lights and amplifiers are and design the electrical system accordingly. If you don’t your party will be a flop.
You need to read more and panic less. Don’t regret posting, just learn a bit more about it. I suggest the op on this thread could help you figure it out.

If one panel won’t be enough, use two. Many of these systems are put together by members where there’s no intention of using all the circuits simultaneously so there’s no risk of overload but even if some drunk boob flipped all the switches the breaker could be reset with no harm done. If you plan on having that party you should design your system to include a few extra batteries and an isolator or that “in excess of 100A” load is going to leave you stranded as well.
My own has an 80A Bussman along with two individually fused 40A relays for additional circuits that exceed the 30A individual circuit rating of the Bussman.

I don't do home electrical as a profession and didn't know that they're wired that way.

I have been working on DC electrics professionally for over 3 decades. I'm building my own panel. No way in hell I'm installing anything in any vehicle and telling the customer you can't use this while you're using that. Not going to happen.
