The Alpine PDX-1.600 is a mono power density digital amplifier that promises up to 600 watts of power, an average amount for the Alpine PDX series. Stackable with dimensions (10-1/8" Width, 7-9/16" Height, 2-7/16" Depth) matching all the other amps in the line, multiple PDX-1.600 (or any in the series) can be purchased and stacked discretely in the trunk or under a seat, saving space and maximizing sound. Wire hookups are located all on one side which help a lot with a clean installation. In terms of sound quality the PDX-1.600 has non-fading pre-amp RCA output, a crossover of 50Hz-200Hz (-24dB/oct) as well as the same power output for both 2Ω or 4Ω loads - the last being a high end feature among its peers.
