I know that it's best to install a cap as close to the amp as possible....
but suppose you want to put an inline fuse between the cap and the amp... would that be a big no no?
in context....
you have two amps installed with one capacitor right "in front" of them in the line of power... but each individual amp calls for a 60amp fuse.
you would want each amp to have their own dedicated 60amp fuse right??
therefore the only place you could do that is just after the capacitor and before the amps, right?
so to restate my question:
is there anything wrong with putting an inline fuse (or a fused distribution block) between a capacitor and the amp(s) it powers?

That's the normal and proper way to do it.  A fuse will let all the power through, but not so much that the wire overheats...as long as the fuse is rated for the wire size.

But...the capacitor is supposed to help with hard bass notes, and doesn't have anything to do with the mids/highs amp.  So, often, the cap is placed after the distro in line to the sub amp.  The wires from distro to amp must always be fused, either at the distro or directly behind it.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

If the cap is going to supply power to one amplifier then I would think it is overkill. If you are going to distro after the cap then that wouldn't be a problem.
Also, like stevdart was reffering to, it would be better to wire the cap after distro to the bass amp.

to clarify the setup more.... the single capacitor would power the two amps..
the two amps power two subs using the same signal via preamp outputs.
and each amp should have its own individual fuse... so the only place to do it is after the capacitor..
so no biggie right? as long as the capicitor is still as close to both amps as possible?
thanks for your responses!

The cap helps out two amps because they are both used for subs:  the cap goes between battery and distro block, both being as close to amps as possible.  Fuse the amps on the wires between distro and amps.  You have it all right.
