alright well im going to have 2 amps that go to my distribution block... found here : http://cgi.ebay.com/Audiopipe-0-4-Gauge-Power-or-Ground-Distribution-Block_W0QQi temZ5871880598QQcategoryZ50550QQssPageNameZWDVWQQrdZ1QQcmdZViewItem and then from the distro block to the battery is a 2 gauge power wire. my amp kit came with the fuse holder that should go on right before my power wire is connected to the battery. my problem is the 2 gauge wire is way too thick to fit into the fuse holder. do i need the fuse?? what should i do?

you COULD just trim the excess off the circumference until it fits - ok electrically, but that would be the wrong (ie - ghetto) way to do it.
My suggestion would be to pick up something like this -
http://cgi.ebay.com/Raptor-24K-Gold-ANL-Fuse-Holder-1-0-or-4-AWG-Gauge_W0QQitemZ 5871182481QQcategoryZ50551QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
And the right size anl fuse for your application.

80A should work for a 105A max current draw. An 80A fuse will have no trouble passing 100A+ for a few seconds at a time. With music - if your amps ever DO require 100A+ it would only be for a fraction of a second. The only concern would be test tones, full volume, for several minutes straight.

Trimming the wire won't make a measurable difference. It will reduce the cross section of the wire slightly - it will probably have to be the equivalent of 4 ga or so to fit in the fuse holder, but resistance-wise you need to consider the diameter of the trimmed wire along with its length, which would be negligible. For comarison - look at the size of the element in the fuse :-)
I don't think your <1" of 4 ga wire is going to have much of an effect on the system ;)
