Sleek Outside - Powerful Inside

QX amplifiers have a dual personality: the outside is a modern, refined design that hides what’s actually under the hood - raw power and cutting-edge technology for all your music needs. When you hear the way QX makes bass thump and midtones twang, you’ll know there’s more here than meets the eye.

Built-in Volt meter

All QX Amplifiers feature a built-in blue-light digital voltmeter. This allows you to easily assess your vehicle’s charging voltage to the amplifier.
