T-Spec designed thieir v12 Series VPNB2 distribution block to handle the high-current power and ground distribution for two amplifiers, and protect them each with a mini-ANL fuse (sold separately). This hefty little block distributes power from a 1/0-gauge positive power cable to two 4- to 8-gauge amplifier power leads, each routed through a mini-ANL fuse. Then, the same block receives the amps' two ground wires and combines them for a single 1/0-gauge ground cable to your car's chassis. T-spec's Universal Screw Design for securing the wires and fuses to the block works with a variety of tools, so you will always be able to change a fuse without having to carry around a special tool. Solid black nickel-plated brass construction ensures reliable power flow, and an impact-resistant polycarbonate cover protects your connections from the weather Features: (2 positive) 1/0-4 AWG in/(2 positive) 4/8 AWG out (1 negative) 1/0-4 AWG in/(2 negative) 4/8 AWG out TPE wrapped soft touch Dual sizes gasket set Water-resistant Solid brass construction Black nickel finish T20 Torx® screws Gate Lock technology
