Is the block insulated on the bottom and around the mounting screws? I'm concerned that it will ground out if I bolt it to my car's metal unibody based on the photos. Is this more of a ground block?

Yes, the connections are insulated from the main body. You shouldn't have any issues mounting to the unibody. Realistically, it could function as a power distribution block or a grounding block. All depends on whether you run positive or negative wires through it. Hope this helps.

The whole body is hard plastic including the bottom.The metal portions are in the guts so you should not have an issue with grounding it out.

When using this distribution block do I have to use 0 gauge in and 4 gauge out or can I use 4 in and 4 out?

You can use 4ga in. It comes with a spacer so you can use 4ga or 1/0ga into the block.

First off, the single terminal side comes with a ferrule that allows a 4 gauge cable to be connected at the single terminal. If you are using it as a positive side distribution block, the feeder cable (input from the battery) needs to be large enough to carry your total connected load. If you are running four 500W amps off the outfeed side, you should run 0 gauge on the input. If you are running a total connected load in the 800W to 1200W range, 2 gauge should work, and if you are under 600W total connected, 4 gauge should do the trick. Of course, your length of run of feeder wire will also determine the gauge you should use, so check out the charts. Now, if you are using this block as a grounding block, Use the same gauge for your primary ground as you used for your primary feeder to your distribution block on the positive side. Some people don't recommend using a grounding block with a common ground as it allows feedback (noise) in your system. I haven't had any trouble with that as long as all my ground connections are clean.

The info here is contradictory. What is the usable input wire size? Is it just 1/0 or can you also use 4gage as input wire? Crutchfield, only one can be right.

I forwarded your question to an Advisor and they responded with the following: You can use either. The connections are secured with set screws, so if you use a 1/0 gauge wire you have to just loosen the screw more to allow for the thicker cable. Then you tighten the screw back on the wire once inserted. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
