About the Crutchfield CK12

Deliver the power your system deserves

Crutchfield's 12-gauge amplifier wiring kit contains the wire and hardware necessary to supply power safely, efficiently, and economically to a high-power radio or a power pack drawing less than 30-amps. This wiring kit does not include RCA patch cables, a remote turn-on lead, or speaker wire. You may need to purchase those items separately, in order to complete your installation.

Power ratings and amp efficiency

Most amplifiers come in two distinct "Classes" of technology with different efficiencies and power wire size requirements. Class AB amps typically feature 50% to 60% efficiency, while Class D amps are usually 75% to 80% efficient. This Crutchfield wiring kit was designed to accommodate the energy demands of a Class AB amplifier with a total output of up to about 140 watts RMS, or a Class D amp with up to 220 watts RMS output.

CTA-2015 Compliant

Crutchfield wire

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.

Hopefully to make my factory Beats system sound better and simple installation. I replaced my factory front and rear door speakers with Kicker speakers. This amp/dsp all in one, along with a very straight forward installation, will hopefully bring out even more sound without breaking the bank and rewiring the whole vehicle.
