ESX QUANTUM QM-FOUR-PP - 4 channel CLASS D

QM-FOUR-PP 4-CHANNEL CLASS D 

The roughly palm-sized 2-channel mini amplifier QUANTUM QM-TWO astonished ESX fans and car hi-fi connoisseurs immediately upon its launch. The small powerhouse with a whopping 240 watts RMS of power was immediately touted as an insider tip. After the improved V2 version topped that last year with an incredible 300 watts RMS of power, ESX is now following up with two additional models in the QM class: The powerful QM-FOUR amplifier is now available for 4-channel applications, and anyone wanting to drive a separate subwoofer can now opt for the new QM-ONE monoblock. Both power bars deliver a whopping 360 watts RMS and are visually perfectly matched. All models utilize modern and efficient Class D technology, combined with EPS®, top features, and perfect sound characteristics. The QM-ONE monoblock is not only visually the perfect partner for the QM-FOUR. If a separate woofer is also required, its application is clearly defined. With a whopping 360 watts RMS at 2 Ω, it provides ample power, and the bass level can even be conveniently adjusted via the remote control.

The QM-FOUR-PP Plug+Play Edition is ideal for amplifying a factory system. Only one condition must be met: The radio must be equipped with a modern Quadlock connector from the factory. The speaker connector insert can be easily removed and connected to the included 5-meter wiring harness of the QM-FOUR-PP. Finally, all that's left to do is supply the amplifier with power, and you're done!
