The ESX Quantum QL 600.4 car amplifier delivers 100 W RMS per channel at 4 Ω and 170 W RMS per channel at 2 Ω. In bridged mode, it provides 340 W RMS at 4 Ω, while total output power reaches 680 W RMS. Class D digital technology and efficiency of up to 86% are combined with a compact design for installation in limited spaces.
It operates on a 24 V electrical system, such as those found in trucks and buses. It features high-level inputs with an error-protection system, automatic turn-on, and Start/Stop support. Settings include HP and LP filters, Bandpass mode, 0–12 dB Bass Boost, and a CH3/4-to-CH1/2 copy function. A compact bass remote control is included.
