Driving a small vehicle doesn’t mean you need small audio to go with it. The SounDigital 400.4 four-channel car amplifier is designed to pack a punch when you have limited space to work with. Each of the channels puts out 100 watts of power to bump up the performance of your front and rear speakers. You can also bridge the amplifier to a two-channel design, doubling the power for a front speaker–only setup. Use it with two-ohm or four-ohm electronics to experience high performance in a compact size.
If you like to crank up the music or go on long trips, the SounDigital EVO X is prepared for that. Dynamic thermal dissipation and recovery reduce the operating temperature, making the amplifier more efficient with less distortion. SounDigital has also added spring-like devices that extend the amp’s lifespan by absorbing vibrations from the engine or bumps in the road.
Crank up the volume in compact and subcompact cars by adding a SounDigital 400-watt EVO X series amp to a factory or aftermarket stereo systems. OnlineCarStereo.com has a low price guarantee and lifetime technical support on this amplifier evolution.
Number of Channels : 4
Dynamic Thermal Dissipation
A system that provides a faster heat exchange with the environment, increasing the efficiency of the amplifier resulting in lower levels of distortion during long working periods.
The technology used in the SounDigital products brings both high performance and power in a small chassis, providing installation solutions for vehicles with limited space and finishing.
Dynamic Thermal Recovery – DTR
The DTR is a dynamic thermal recovery system which always maintains a high efficiency of the amplifier by accelerating the thermal exchange of electronic components with the heatsink.
Conductive copper layer
Vibration Absorption Device
SounDigital added a new device to the EVO X products which act like springs, reducing the impact of vibration on the electronic circuit board, thereby increasing the life and reliability of the amplifiers.
