I'm trying to setup my Mobile in my truck. I managed to cleanly install 4 gauge wire from the Battery to my radio rack. I went to the Auto Parts Stores looking for a power distribution block that would handle up to 50 amps. They all gave me the stink eye and tried to sell me a cheap fuse block. Somebody turned (around 25 years old) me on to Crutchfield. Wow, those kids have to handle much more power in their souped up stereo systems. Crutchfield carries a full line of power distribution blocks that are almost pretty and can handle any mobile RF amp I will ever use.
