i'm trying to install some amps. Having trouble crimping the wire to the piece that attaches the wire to the battery though. Anyone? Anyone? thanks in advance.

 

Thats a non-insulated loop I presume. I believe most wire stripers dont have a non-insulated crimper for anything above 10 gauge thickness, but when I did mine, I think I placed the end on a board, then hit a screwdriver with a hammer into the collar. If it's a good fitting, it should be a seamless collar, and therefore you should get a decent crimp. If worse comes to worse, torch it and solder, then cover it up with color matching heat shrink. It'll look fine.

 

I crimped 4 ga. wire to a ring terminal using 2 pliers.
One with a semi-sharp edge to crimp the actual wire and
the second to squeeze the handles of the first.

 

Use a vise if you've got one, or go bum a favor off your local shop.

 

a screw down... screw there pretty cheap
