What it is and who it is for

The VEVOR CB-400D-C is a 400W RMS Class D monoblock car amplifier designed to power subwoofers in sedans and pickups. It delivers clean bass through ultra-low distortion and operates on a 9-16V DC supply. The unit includes a wired remote level controller for driver-seat adjustment.

The spec that decides fit

This amplifier is stable at 1, 2 and 4 ohm loads, so it matches single or dual voice coil subwoofers in 10-inch and 12-inch sizes. Frequency response runs from 15 to 250 Hz with a signal-to-noise ratio of 75 dB at 1W and 102 dB at maximum output. Peak power reaches 800W at 1 ohm.

Installation and common issues

The chassis measures 6.9 x 8.9 x 2.4 inches and weighs 4.2 lbs, mounting with four included screws. A 16.4 ft remote cable routes to the cabin for real-time bass control. Installers must verify the vehicle electrical system stays within the 9-16V range and use the supplied fuses to protect the power wire.

Questions about this item

How much continuous power does the 400W RMS rating actually deliver to a subwoofer?

The amplifier provides 400W RMS at 1 ohm, giving a subwoofer sustained power for deep bass with low distortion.

What does the 15-250 Hz frequency response limit in a real installation?

It restricts the amplifier to sub-bass and low-mid frequencies, so it drives only a subwoofer, not full-range speakers.

Will the 6.9 x 8.9 x 2.4 in chassis fit under a typical car seat?

At 176 x 226 x 60 mm it is compact enough for most under-seat locations; four mounting screws are included.
