Description

The Infinity Reference 3004A is a four-channel car amplifier for powering front and rear speakers or a supported bridged configuration. Both speaker-level and RCA inputs are provided, along with preamp outputs for feeding an additional amplifier.

Power and tuning

  • 75 watts RMS x 4 at 4 ohms.
  • 100 watts RMS x 4 at 2 ohms.
  • 200 watts RMS x 2 bridged at 4 ohms.
  • Variable 32–320 Hz high-pass and low-pass filters.

Choose the speaker configuration before setting the crossovers and input level. Infinity recommends 8-gauge power and ground leads; the amplifier does not include a complete power-wiring kit. Confirm the mounting space and cable route before installation.
