Taramps DS 440X4 440W 4-channel car amplifier

Compact four-channel amplifier

The Taramps DS 440X4 is a Class D car amplifier that delivers 440W RMS total power across four channels at 110W RMS each into 2 ohms. Its full-range design reproduces frequencies from 8Hz to 26KHz so every part of the audio spectrum is covered. The chassis measures 6.3 by 1.73 by 5.71 inches and weighs 1.32 lb, making it small enough to mount in tight spaces.

Installation requirements and space saved

The unit operates on a 12V vehicle electrical system with a working range of 8VDC to 16VDC and draws 0.8A at rest. Fixed high-pass and low-pass filters are both set at 90Hz with a 12dB per octave slope, removing the need for external crossovers. Input impedance of 18K ohms matches standard head-unit outputs, and built-in short-circuit protection safeguards the output stage. The compact footprint frees up cabin or boot space that a larger multi-channel amp would occupy.

Power delivery and practical limits

At 12.6VDC the amplifier can draw up to 23.5A during musical peaks while nominal consumption is rated at 47A, so the vehicle’s charging system and wiring must support that current. Four channels at 110W RMS each provide ample headroom for a component front stage plus coaxial rear speakers or a pair of subwoofers bridged across two channels. The fixed 90Hz filters mean the amp cannot be tuned for sub-bass duties below that point, and the 2-ohm per channel rating limits use with lower-impedance loads.
