The Rockford Fosgate R500X1D is known as the PRIME R500X1D. This 500-watt mono amplifier utilizes Class-D circuit topology, which is highly efficient. It has the capability of operating a 2-Ohm load. It provides 12dB/octave Butterworth crossover to handle both low and high frequencies efficiently. RCA pass-thru outputs are another feature on this unit.
On-board Punch EQ
On-board Punch EQ is on this amplifier with the addition of +18dB boost @ 45Hz. This EQ helps overcome your car’s difficult acoustical shortcomings for better sound quality within the vehicle. This is a dedicated subwoofer style of amplifier. The R500X1D is an ideal addition to a two-amplifier sound system. One amp runs the subwoofers, while the other on runs mid/highs.
Power ratings for this amplifier are CEA-2006 compliant. These guidelines ensure that the power ratings are true and not fabricated ones just to sell the amplifier to you. This unit also is CE compliant, which means it follows the essential environmental and safety requirements according the European Directives (768/2008EC). In addition, it is a Class-D amplifier and this shows it has a high efficiency rating that reduces the amount of current needed from the charging system.
It is important to point out that the RMS Continuous Power of this unit is 300 Watts x1 @ 4-Ohms and 500 Watts x 1 @ 2-Ohms. In addition, the Sum of Rated Power is 500-Watts RMS. Frequency Response is 20Hz to 250Hz +/-1dB. The dimensions of the R500X1D are 1.98” height x 6.77” width x 8.5” length. This amplifier also receives power through a MOSFET power supply and has short circuit and over current protection. It comes with a 1-year standard warranty.
