A Kicker brass battery terminal allows you to connect their amplifier power kits to primary or auxiliary batteries so your system has a reliable amperage feed. It’s competition-grade and can be set for positive or negative polarity. Kicker also makes termination blocks, distribution blocks and other battery power accessories.
