Terminals

Battery Terminals built for competition-level electrical upgrades ensure maximum current flow and rock-solid reliability. Designed for high-amperage car audio systems, these terminals provide secure connections for oversized power wire, upgraded grounds, and multiple cable runs. Ideal for SPL builds, demo vehicles, and high-power daily drivers, competition battery terminals reduce voltage drop and keep your electrical system locked in under extreme demand.
