1x Metra MLAK8-20 8GA Marine Amp Kit 20ft w/50A Waterproof/Protected Breaker (MLAK8-20)
Power your marine amplifier with a wiring kit that can withstand the harsh environment and still deliver full sound performance. Fully tinned wiring ensures that these amp kits won’t corrode or oxidize and turn green after a season on the water. Oxygen-free copper provides a reliable connection with maximum conductivity. By using 100% virgin copper the tin won’t flake off, something commonly seen when using recycled copper materials. While it is also common to tin just the tips of the wire for cost savings, this practice does not actually provide any benefits. Metra’s amp kits use fully tinned copper wire from top to bottom that can withstand a harsh marine environment and salty air. The ignition-protected 50-amp circuit breaker is IP67 rated with stainless steel connection points for corrosion resistance
