About the Crutchfield Primary Wire
Don't forget the trigger signal
Don't forget the trigger signal
Car amplifiers require a 12-volt signal, coming from a receiver or other power source, to trigger the amp to turn on. Crutchfield's Primary wire serves this purpose perfectly and comes in blue, the standard color for an amplifier's turn-on lead.

Crutchfield wire is made of oxygen-free copper, with no impurities that could raise its resistance to a signal's flow or add interference. Crutchfield wire meets all Consumer Technology Association (CTA-2015) standards for size, resistance, and insulation quality. Warranty: 1 year.
