Rockford Fosgate Prime R500X1D Monoblock 500 Watts Amplifier

The Amp At A Glance:

• 2 Ohm stable: Delivers 500 Watts x 1 at 2 Ohm or 300 Watts x 1 at 4 Ohm RMS continuous power.
• Flexible bass tuning: Variable Punch Bass, a 0-degree/180-degree phase switch, and a 12 dB-per-octave Butterworth crossover help tailor subwoofer performance.
• Efficient Class D design: Class D topology and a MOSFET power supply provide dedicated monoblock power with 89 percent average efficiency at 4 Ohm.
• Remote level control: The included Punch Level Control provides convenient adjustment from the driver’s seat.
• Easy system expansion: RCA pass-thru outputs allow another amplifier to be daisy-chained into the system.
• Built-in protection: Short-circuit protection, over-current protection, and real-time output and power-supply thermal sensing help safeguard the amplifier.

The R500X1D gives a subwoofer the dedicated power it needs to add weight and impact to music. Its monoblock design keeps the focus on bass, while the Class D circuit topology delivers that power efficiently.

Variable Punch Bass and crossover controls let you shape the low-frequency response to suit the subwoofer and listening preferences. The phase switch provides another useful tuning option, while the remote Punch Level Control keeps bass output within easy reach for quick adjustments from track to track.
