T-SPEC’s VBDB4 is a unique distribution block that combines the most practical, sophisticated features in its class with the highest performance on the market to unleash the full power of a car audio system. Premium construction and materials allow for a highly conductive block with 5mm thick solid brass bus bars and a satin gunmetal finish, with dual 0/1 ground inputs to match the dual 0/1 positive inputs. This block also has a built-in amplification relay for boosting the current rating of the amplifier turn-on wire, distributing it across all 4 outputs. The 4 mated outputs group remote, 4ga power, and 4ga ground together for quick identification, and an anti-short sub-cover isolates the returning ground bar and terminals. A Blown Fuse Indicator (BFI) LED light for each circuit indicates which fuse to replace and 3 rapid replacement spare MANL fuse locations built into the case make replacement simple and easy. A TPE wrapped soft-touch cover completes the high-end look for this premium performance distribution block.
