KICKER brass is smaller and more functional than ever, covering the details every installer can appreciate. Uses Versa-Gauge connection points -oversized convex screws for rock-solid termination and secure connections. Wire receptacles work with most size wire (1/0-8 Gauge or 4-8 Gauge) for clean, sharp install. All brass uses stout 5mm screws so only a single wrench is required. No-fail Battery Terminal includes a negative-post adapter collar that locks into place for tight grip and best connection. Innovative Terminal comes with red and black fasteners for the tinted cover to match applications. Terminal also includes convenient Gauge side terminal for additional connection options and flexibility. Fuse holders feature K-Mount two-stage mounting holes to accommodate screws or zip ties for added stability.
