4-Volt Front, Rear and Sub Preouts w/ LPF
Turning up the juice with a high-voltage, 4-volt preamp output will definitely produce a louder, clearer audio. A 4-volt preamp output improves the system's dynamic range, reduces system noise and makes the system play louder than one with a 2-volt output headunit. The dynamic range improvement comes from a greater difference between the quietest and loudest audio signals. This benefit is particularly evident when playing digital source material such as a CD or music files.
