ESX QM-Four-PP | 4-channel mini amp

The palm-sized QUANTUM QM-TWO 2-channel mini amplifier caused a sensation among ESX fans and car audio enthusiasts immediately after its release. This little powerhouse, boasting a hefty 240 watts RMS, was instantly hailed as a hidden gem. After last year's improved V2 version topped even that with an incredible 300 watts RMS, ESX is now adding two more models to the QM series: the powerful QM-FOUR amplifier for 4-channel applications, and the new QM-ONE monoblock for those wanting to drive a separate subwoofer. Both powerhouses deliver a robust 360 watts RMS and are visually perfectly matched. All models utilize modern and efficient Class D technology, combined with EPS, top-of-the-line features, and exceptional sound characteristics. The QM-ONE monoblock is not only a visually perfect partner for the QM-FOUR. If a separate subwoofer is to be powered, its application is clearly defined. With a hefty 360 watts RMS at 2 ohms, there's plenty of power, even conveniently adjustable via a bass level remote. The QM-FOUR-PP Plug+Play Edition is ideal for upgrading a factory-installed system. Only one condition needs to be met: the factory radio must be equipped with a modern Quadlock connector. The speaker connector insert can easily be removed from this connector and connected to the included 5-meter cable harness of the QM-FOUR-PP. Finally, the amplifier just needs to be powered on and it's ready!
