The Stinger SPD5623 is a fused power distribution block designed to split high-current feed into multiple runs for aftermarket car audio installations. It accepts two 1/0-gauge inputs and provides four 4/8-gauge outputs with MAXI fuse protection to guard downstream circuits.

Built with deep wire recesses to eliminate exposed conductor and oversized set screws to ensure secure contact, the unit is intended for 12V automotive electrical systems and common car audio wiring configurations. It installs inline with battery and amplifier power wiring to distribute fused power safely.
