interior wiring

ive been looking for a small panel with terminals that i can have one terminal row wired to a +12v source and the other side to ground. then use this to wire all my interior accesories too. instead of having to wire each individual thing to the battery or some other place, i can have ONE wire from the battery, have it go to the panel, then hook everything up to the terminals. does anyone get what i mean? if so does anyone know where i can find something like this? thanks

You ever seen those fancy lil wire splitter boxes for car audio? It takes a 2-4 guage wire straight off the battery and splits it to 2 , 4 or 6 with bolts to hold down the wires. This way you can have a 12 volt source anywhere in the car and any new acessories could be tee'd off there. Then for ground you just put the negative wires to the body with screws or bolts.
