X2 Series Amplifiers
Just because it's the smallest amplifier in the line doesn't mean it can't pack a serious punch. The X2 450.4 may be the baby of the X2 amplifier line, but it provides an impressive 85 Watts per channel. This 4-channel amp can drive even the best speakers to their sonic limits in your vehicle.
One amplifier running an entire system without compromise to sound quality of overall performance? Yes, it's true! Robert Zeff has done it again with a single package solution designed to run your speakers and subwoofers from a single, compact amplifier.
The X2 600.4 amplifier delivers 150 watts into 4 channels at 2 or 4 ohms to provide your mids and highs more than enough dynamics and power to satisfy even the most demanding or critical of listeners.
Capable of producing 150 watts to each of the four main channels; the X2 1100.5 provides enough power and dynamics to satisfy any audio enthusiast while still leaving enough in reserve for those late night jam sessions.
