Rockford Fosgate P300X1 300 Watt Mono Class AB Car Amplifier:

  • 300 Watt Punch Series Monoblock Class AB Car Amplifier
  • TRANS•ana topology - simplifies the signal path of the amplifier that results in greater reliability and sound quality
  • MOSFET power supply for incredible power
  • LED indicators: Power, Protect, and Thermal
  • Balanced Differential inputs - filters and eliminates noise picked up from the RCA signal cables as they are run through the vehicle
  • C.L.E.A.N circuit that allows you to properly optimize input signal to output capability for proper signal to noise ratio and prevent damaging distortion
  • MEHSA3 utilizes a proprietary process that yields up to five times better heat transfer than traditional FET mounting techniques that lowers distortion, increases durability and prolongs the output device life span
  • DSM - An industry-leading manufacturing process, DSM utilizes high-speed robotics, high-quality 1% tight-tolerance parts and large board traces which improves efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature
  • NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances
  • DTM - Dynamic Thermal Management evenly distributes heat across entire amplifier cast aluminum heat-sink without noisy fans utilizing convection cooling
  • Provides three way protection circuitry, which includes thermal, overload and speaker short protection
  • Integrated heavy-duty aluminum alloy vented heat sink for utmost heat dissipation
  • Requires minimum 8 gauge power and ground wiring for installation
  • CEA-2006 compliant amplifier
  • Frequency Response: 20Hz to 20kHz +/- 1.0dB

Inputs and Outputs:
  • Mono channel operation
  • Nickel-plated RCA level inputs
  • Nickel-plated RCA level outputs
  • Input sensitivity is 150 mV to 12V
