ESX QS-FOUR – Ultra Compact 4-Channel Class D Digital Amplifier
ESX QS-FOUR Product Overview:
The ESX QS-FOUR amplifier is the perfect answer for those looking to add power to their original audio system without major modifications . The successor to the famous QS-TWO , it maintains a nano format while offering 4 powerful channels in a slightly larger enclosure (90 x 35 x 80 mm).
With up to 4 x 60 Watts RMS , this Class D amplifier far exceeds the performance of amplifiers integrated into original car radios, while maintaining very low power consumption (5 to 10 A on average). Ideal for discreet installation behind the dashboard, especially in vehicles with ISO connectors.
