And the "thing" in between the two "meters" is a distribution box for high powered stereo systems. You bring a large gauge electrical wire into it and add smaller gauge wires to it to feed the different amps and other stereo items. Most of the metal where wires attach should be chrome plated brass, I used to sell some that were "gold" plated brass. Don't know that it was actual gold plating or not.
