Description The power distribution block can help reduce the number of wires and AWG-compatible gauges during the installation of a vehicle's media system. It is finished in plating and has a tough clear plastic protective cover. This distribution block helps to remove the need for several separate wires running from the main power source and gives you a more clean and professional installation. You'll also need to place in-line fuses between the distribution block and your vehicle's media system.
