ESX Q-ONE v2 (24 volts)

The ESX Q-ONE v2 (24V) from the QUANTUM series is a compact, high-performance 1-channel Class D amplifier designed specifically for vehicles with a 24-volt electrical system. This makes it particularly well-suited for use in trucks, commercial vehicles, and other vehicles with a 24-volt electrical system.

With an RMS output power of up to 700 watts into 1 ohm, this monoblock amplifier offers ample power reserves for high-performance subwoofer systems. Thanks to its efficient Class D technology and compact design, the amplifier can be installed even in spaces with limited room.

For custom tuning of the bass range, the Q-ONE v2 features an adjustable low-pass filter, a subsonic filter, a bass boost, and continuous phase control. The amplifier can also be integrated into existing factory sound systems via the high-level inputs with an automatic power-on function.

A compact wired remote control allows you to conveniently adjust the bass level from the driver's seat.
