The PRS-D2200T, however, offers an improved maximum power of 1200w, a superior frequency of 10Hz-40kHz, and an enhanced signal-to-noise ratio of 100dB. The PRS-D2200T also includes additional features such as independent left/right signal circuitry for reduced interference, a custom-made power supply capacitor bank for improved stability, and an energy saving design that in fact draws less energy from the vehicle’s alternator, therefore reducing fuel mileage. Priced at $449.95, the Pioneer PRS-D2200T is considered a worthwhile investment due to its inclusion of many features at a relatively affordable price.
