Panasonic CY-PAD1003U

The Panasonic CY-PAD1003U is a single channel digital car amplifier with a maximum power output of 1100 Watts. Compared to the 45% to 55% efficiency of a conventional analog amp, a "digital" amp can attain over 70% to 80% efficiency by converting the input signal to a pulse signal and operating its output stage in "class D" or switching mode.

 There is a Low-Pass filter for Subwoofer, a feature that makes it easier to upgrade to subwoofers. There are several line-out jacks for expansion, which lets users easily connect multiple amps, while keeping the wiring neat for an attractive appearance. It has intelligent Bass Servo Circuit which results in a bass that is more coherent with the rest of the frequency spectrum, achieving greater fidelity to the original sound.
