Phoenix Gold ZXM500.4i – 4-channel mini-amplifier
The Phoenix Gold ZXM500.4i represents the next generation of compact power and precision. This 4-channel Class-D mini-amplifier builds upon the popular ZXM500.4, delivering improved performance, easier installation, and even better OEM compatibility – all in an extremely compact chassis.
The amplifier is developed for modern car installations where space is limited, but demands for sound quality and flexibility are high. With up to 1000 W max power, high efficiency, and advanced Class-D technology, the ZXM500.4i delivers clean, controlled, and powerful sound for both speaker systems and bridged setups.
The extended 20V high-level input allows direct integration with OEM systems without additional adapters, while the choice between Auto Start or Remote Trigger provides maximum installation freedom. New quick connectors and adjustable load resistors (OIS) ensure trouble-free mounting and correct system matching – even in sensitive factory installations.
The ZXM500.4i is the obvious choice for both OEM upgrades and compact high-performance systems where efficiency, reliability, and sound quality are in focus.
