ESX QS-FOUR-ISO – 4 Channel Class D Ultra Compact Plug & Play ISO Amplifier
Product presentation:
The ESX QS-FOUR-ISO amplifier is the ideal solution for boosting your factory audio system without modifying your vehicle's wiring. The successor to the highly acclaimed QS-TWO , this ISO version maintains an ultra-compact format (90 x 35 x 80 mm) while adding two additional channels , for a power of 4 x 60 Watts RMS .
Its ISO Plug & Play design allows direct integration into vehicles with an ISO connector , without the need for additional power cable runs. Thanks to its high efficiency (up to 90%) , it only consumes 5 to 10 A , which is perfectly suited to the original power supply.
The QS-FOUR-ISO drastically improves sound quality, often limited by the weak amplification of factory radios. In addition, it includes an RCA output for an active subwoofer, making it an ideal basis for a scalable system.
