  • THD of 0.01 % and >90 dB S/N ratio preserve detail

Four-Channel Class-D Amplifier

The DS18 G1800.4D is a four-channel Class-D car stereo amplifier rated for 1800W peak power. It delivers 4x150W RMS at 4 ohms, 4x230W RMS at 2 ohms and 2x430W RMS when bridged at 4 ohms. The unit suits system builders who want a single amplifier to drive front and rear speakers or a bridged pair of subwoofers. Buyers needing more than four channels or a dedicated monoblock for higher subwoofer power will need additional equipment.

Matte Black Chassis With 4 GA Terminals

The matte black body uses 4 GA power and ground terminals that accept thick wiring for reliable current delivery. Protection circuits cover thermal, overload, DC output, short-circuit, voltage input and clipping faults, with LED indicators for power, protection and clip status. No onboard cooling fan is fitted, so airflow around the chassis must be considered during installation. Installers without 4 GA cable or a distribution block will need to source those separately.

Selectable Crossovers And Phase Control

Each channel offers selectable low-pass, high-pass or flat crossover settings plus a 0-180 degree phase adjustment for time alignment. Input sensitivity ranges from .25-6V to match various head-unit outputs. No remote level control, voltmeter or bass-knob accessory is included, so gain and crossover tuning must be done at the amplifier. Users wanting dashboard bass adjustment or real-time voltage monitoring must add third-party accessories.

Questions about this item

What does the 2-ohm minimum impedance mean for the 1800W peak rating?

The 1800W peak figure is the absolute maximum; continuous RMS power is 4 x 230W at 2 ohms and 4 x 150W at 4 ohms per channel.

What gauge power and ground wire does the 4 GA terminal require?

The amplifier accepts 4-gauge power and ground cables directly; use 4 AWG or larger for the main supply run.

How do I set the selectable crossover and 0-180 phase for a 4-channel install?

Choose LPF, HPF or Flat per channel pair, then adjust the 0-180 phase dial to align subwoofer output with midrange drivers.
