$299.99$329.99 (-9%)
Overview
Park a half-kilowatt mono under a seat with the Rockford Fosgate T500X1br Power Series Class-BR amplifier. Continuous power is 175 watts RMS at 4 ohms, 300 watts at 2 ohms, and 500 watts at 1 ohm. Clip-detection LEDs, high-level auto turn-on, and PLC2 remote readiness suit compact subwoofer installs. Plan on 8 AWG power cable and a 60 Amp fuse (sold separately).
Product details
500 watts of Boosted Rail mono power
T500X1br uses patented Class-BR Boosted Rail circuitry to deliver 175 W x 1 at 4 ohms, 300 W x 1 at 2 ohms, and 500 W x 1 at 1 ohm in a chassis only 1.6 x 4.3 x 8.3 inches. Energy stored on the rails is released as demand rises, so the amp can hit that 500-watt continuous rating without a large traditional heat sink footprint.
Bass filtering and remote control
A low-pass crossover sweeps 50–250 Hz at 12 dB/octave Butterworth. Punch bass adds 0 to +18 dB at 45 Hz. An optional PLC2 remote provides Punch Level Control from the dash and is sold separately. Frequency response is 20 Hz–220 Hz.
Install details
High/low-level input arrives on a 4-pin harness with 150 mV–12 V sensitivity and high-level auto turn-on for factory radios. Power uses an 8 AWG detachable compression terminal; speaker outputs accept up to 10 AWG. Dual fans cool the extruded aluminum chassis. Plan on a 60 Amp fuse (not included), about 30 A average music current draw, and a suggested 75 A alternator class supply.
