The Rockford Fosgate P500-1bd is a mono amplifier designed for high efficiency subwoofer support in a car audio system. This has the same features and design as the Rockford Fosgate P1000-1bd, but outputs at 500 Watts rather than 1000. Output is dedicated to the low frequency range of 20Hz to 250Hz, making the design specifically targeted to subwoofers and incompatible with any other kind of speaker. Class-bd amplifiers such as this one have a 75-80% efficiency rating, enabling more output than traditional A/B class amplifiers. A 1-ohm resistance capability enables the connection of two 4-ohm DVC subwoofers, or alternately an array of four separate 2-ohm DVC subwoofers. Both RCA outputs and 8 - 18 AWG wire connections are available for output, and differential inputs reduce noise picked up by the cabling as it travels to the amplifier.
