Question:
What makes Class D amplifiers like the Hifonics BXX4000.1D more efficient?
Answer: Class D amplifiers, such as the Hifonics BXX4000.1D, utilize a different amplification method that converts a greater portion of the power supply into audio output compared to Class A or AB amplifiers.

Hifonics Mono Amplifiers Editorial Review
The BXX4000.1D is a mono-channel amplifier capable of producing 4000 watts RMS at 1 ohm. This amp is not bridgeable and features two positive and negative inputs but both go to the same channel for ease of multi-sub installations. It can push various subwoofers such as two 12" vxf skar and 2-12" Soundqubed hds312. The amp is power-hungry and requires a cap battery or an additional battery when pushing 3 15 CVX subs, for instance. The BXX4000.1D amplifier is being well received by customers, with most reviewers indicating satisfaction with how it powers their subwoofers. However, some customers have experienced defects in the product, particularly dented or broken parts, and defective sound output after receiving it following which they received no help from the seller.
