Buying advice

When choosing an amp wiring kit, consider the wire gauge based on total wattage (4 gauge for up to 1000W RMS, 0 gauge for larger systems). OFC wire is more conductive and resistant to corrosion than CCA, but costs more. Ensure terminals and distribution blocks match your wire gauge and are made of brass or copper for durability. Fuse holders should be placed within 18 inches of the battery for safety.
