Black 12V Mini Class D 4-Channel Car Amplifier — 4×125W @ 2Ω, Bridgeable to 2×225W, 500W Dynamic RMS, 87% Efficient

Compact high-performance 12V Class D amp built with Brazilian technology for powerful sound in a small package. A high-speed MOSFET power supply paired with premium transistors and a compact heat sink delivers efficient output without sacrificing audio quality. Power and efficiency: rated for 500 Watts of dynamic RMS power, this 4-channel amplifier provides 4×125 Watts at 2 Ohms per channel while achieving an 87% efficiency to reduce battery draw. Bridgeable configuration: channels can be bridged to increase output — with a minimum impedance of 4 Ohms per bridged channel the amp delivers 2 × 225 Watts RMS for higher-powered speaker setups. Protection and sound range: features a smart 2-way protection circuit to guard against overheating and speaker short circuits, and offers a full-range frequency response from 10 to 24,000Hz. Ideal for tight installations, this mini car amplifier packs robust performance and clear full-range audio into a space-saving design.
