Deliver the power your amp deserves

Crutchfield's 8-gauge amplifier wiring kit contains the wire and hardware necessary to supply power to your amplifier safely, efficiently, and economically. This wiring kit does not include RCA patch cables 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 420 watts RMS, or a Class D amp with up to 650 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.

A
no plans of running multiple amps, so i don't need 4 gauge or a distribution block, simple and easy kit. Back in the day I would have had a minimum of 2 amps-high and lows and in several cars multiple low amps in addition to the high amp. Older now, and looking for tight simple bass to round out the system. Would have went with the Kappas but i couldn't outfit the entire JK with 2 way coaxial so instead, I opted for an entire JBL setup. [ Rhasean  Nov 29, 2017 ]
