RAVE Series 800 Watt RMS 2-Ohm 4-Channel Class D Car Audio Amplifier RAVE 800.4

This Listing Includes:

  • (1) B2 Audio RAVE 800.4 4-Channel Amplifier

The B2 Audio RAVE 800.4 delivers clean, flexible full-range power for daily-driver systems, door speakers, mids, highs, and custom amp-rack builds. This compact 4-channel Class D amplifier produces up to 800 watts RMS total at 2 ohms—giving your speakers the stronger, cleaner output they need without taking up unnecessary space.

Run four speakers at 2 ohms for up to 4 x 200W RMS, or bridge the amplifier into a powerful 2-channel setup with 2 x 400W RMS at 4 ohms. Adjustable high-pass and low-pass crossovers let you dial in the right frequency range for your speakers, whether you are upgrading factory audio, powering a loud daily driver, or building a more customized system.

The RAVE 800.4 is 2-ohm stable per channel, internally fused, and built with 4-gauge power terminals for a clean, reliable installation.
