Arc Audio MOTO 600.4 High-Performance 4ch Motorcycle Amplifier

Designed specifically for the motorcycle and power sports market, the MOTO 600.4 amplifier is the high-performance solution for today’s extreme music lovers. Capable of delivering over 600 watts into 4 ohms from all four channels, the Moto 600.4 takes your factory stereo from zero to hero in a single package solution.

When it comes to dynamics and overall sound quality nothing beats raw power except clean power. With the Moto 600.4 amplifier that is exactly what you get. Having 150 watts into 4 channels at 2 or 4 ohms available gives your speakers more than enough dynamics power to satisfy even the most demanding of listeners. This amazing power is produced without taxing your factory charging system beyond its limits. The Moto 600.4’s patent-pending power supply design achieves more than 90% efficiency, allowing you to get full power without needing a ton of electrical current form your bike.

Compact, elegant and full of unmatchable power, the Moto 600.4 is small enough to fit inside the factory fairing of all 2000 – 2015 Harley-Davidson full fairing motorcycles without the need for modifications, custom installation or devaluing your motorcycle. Its compact size allows you to achieve that personalized "Big Sound" without the loss of valuable bag space.

The best part, we don't creative or non-standard test procedures or instructions to get our rated power numbers. Experience real power from a real amplifier that delivers nothing but the BEST sound and performance possible.
