The Copper Series 4.2: A new line of reference-grade car audio amplifier built for the true audiophile.

Designed with competition-level audio in mind with the help and support of our award-winning sound quality competition team, the Copper Series Amplifiers deliver unmatched detail, clarity, and signal transparency. For those using high-end DSPs, the built-in crossovers and other front end analog audio components can be completely bypassed and circumvented at the flip of a switch, ensuring a pure signal path for ultimate fidelity with ARC Audio's "bypass" function.

Beyond performance, the Copper Series makes a statement with its refined aesthetics. Featuring a satin silver chassis with brushed copper-plated accents, these amplifiers exude a level of craftsmanship that matches their sonic performance. For those who prefer a more understated look, an additional set of anodized satin silver end plates is included for a customizable finish.
