ESX QM500.4 Quantum 4-Channel Class D Mini Digital Car Amplifier

ESX Quantum QM500.4

Digital amplifier power has never been more compact and affordable: With a size of just 190 x 35 x 102 mm, the three new ESX QUANTUM QM miniature power plants are convincing all along the line. The QM amps offer state-of-the-art technology in a very small space and are all solidly constructed. All three amps are based on the somewhat larger sibling models of the ESX QUANTUM QL series, only a bit more compact and much easier to install. Thanks to the high level inputs including EPS® and the automatic turn-on function, they are also perfectly suited for integration in factory sound systems. Each model is also equipped with a compact bass level remote control.
