I'm looking at adding some power distribution blocks to clean up the electrical wiring in my project car.

I'm curious why distribution blocks have inputs and outputs? Looking at most of them they are nothing more than a piece of highly conductive metal in a plastic case.

If I mis-use an input as an output is Ohm going to roll over in his grave?

I don't quite know why, but that post was funny. Ohm rolling over in his grave, HAHAHA.

But anyways, power dist. blocks are for just that, power. Conntect some wire, preferably <4 AWG to the pos battery terminal, and run that to the INPUT of the block. Then run wire, preferably <8 AWG (depending on application), from the OUTPUT of the block to the components you are trying to power. Install all of the necissary fuses, and grounds, and you set.

Blocks can also be used for ground wires from multiple components (amps usually) to one point. I.E. the ground wires from the amps to the OUTPUT of the block, then wire from the INPUT of the block to the frame.

It's that simple.

Hahaha, Ohm. Rolling over in his grave. I'm not making fun, just the visual of that is hillarious.

Ins and outs only matter if using a fused distro block, otherwise it doesn't matter.

i have the rockford rp1732-c dual amp kit and the only thing i dont know what to wire up is the distro blocks. i tried it with out directions and i blew the 60 amp fuse. so im not gonna touch it until i get some help. im not stupid ive just never worked on one before. i was preferably looking for a diagram or link.

thanx

What part dont you understand in the installation of the wires?

You do realize that one end will have a large guage opening which normally comes from the battery. The remaining holes / exits will supply what ever device(s) the power it requires.

If the fuse blows immediately upon power up, you have a dead short. If the fuse(s) blow shortly there after, you either have a over current situation, or the fuse is too small for the circuit.
