Need clean power for your car's speakers but don't have much space? The Soundigital SD400.4 EVO 4.0 is a super compact 4-channel amplifier module. Don't let the small size fool you – it's packed with tech. It features patented DTR (Dynamic Thermal Recovery) technology, which means it manages heat incredibly well for high efficiency and reliability. Here's the power you can expect: At 12.6 volts into 2 ohms, it's 4 x 100W RMS. Into 4 ohms, it's 4 x 66W RMS. If your car's electrical system is running at 14.4V, you get even more. It can also be bridged for more power to a pair of speakers. It has a built-in crossover (high-pass and low-pass), a great signal-to-noise ratio, and a damping factor of 200 for tight bass control. Dimensions are a tiny 11\ x 4.5\ x 2\, and it weighs just about 1 lb. Perfect for powering a set of component speakers or coaxials in a tight install. Comes with a solid warranty (273 days mentioned). A high-tech, space-saving solution for great sound.
