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.

[ BRETT  Nov 04, 2020 ]
Q

[ David  Apr 26, 2020 ]

It is not.
[ Calvin  May 19, 2020 ]  Staff
Q
Is wire copper or copper clad aluminum?
[ Esteban  Jan 11, 2020 ]
2 answers
A
It's copper. And despite what Eileen said, you can clad copper with aluminum, that's what CCA is. She completely destroyed her own argument about dissimilar metals, as tin and copper are different metals too. Or doesn't she realize tin is a metal?
[ Dan  Nov 11, 2020 ]
A
You cannot copper clad aluminum they are dissimilar metals, however, you can clad copper cable with tin which is what the cables that come with these speakers are.
