Distribution Block 4/0 - 10 AWG. Tool Maker. Up to 22 Wire Connection!!!!.  This is the ultimate car audio distribution block. It has 12 huge .470" dia.  connections, 6 .360" dia. Connections  and 4 .201 dia. connections for smaller wires. I am shipping these with clear shrink wrap. These are great for positive connections but even better for negative, multi amplifier connections because it ensures that each amp has the same exact ground potential. This is beneficial for preventing  whining or whistleing noises. Thanks for looking!
