The new Wet Sounds Fust Distribution Block utilizes nickel plated brass for maximum current transfer and marine-rated corrosion resistance. Features 2-inputs supporting 1/0 gauge wiring, or 4 gauge with included reducers, with 4-outputs to support 4 or 8 gauge wiring. To keep that power moving safely, two ANL fuses or up to 4 mini-ANL fuses will fit securely in place to keep current moving to your amplifiers. Securely hold your wiring in place thanks to the Wet Sounds exclusive wire tie mounts built right in for a nice clean installation.
