B2 Audio Monoblock Amplifier 2500W 1-Ohm Class-D RGB LED Lights Riot 2500 V2



This Listing Includes



  • (1) B2 Audio Riot 2500 RGB V2 Monoblock Amplifier

  • (1) Bass Level Control with Clip Indicator


The B2 Audio Riot 2500 RGB V2 is a Hi-EF Class D monoblock built to drive subwoofers with serious power from a compact chassis. At 14.4 volts, it puts out 2,500 watts RMS at 1 ohm, 1,400 watts at 2 ohms and 800 watts at 4 ohms.

It gives you full control over your low end. The low pass filter adjusts from 50 to 250 Hz, the subsonic filter from 10 to 50 Hz, and you get 0 to 12 dB of bass boost plus a 0 to 180 degree phase control to help your subs blend with the rest of your system. The included bass level control lets you adjust output from the driver’s seat, and its clip indicator shows you when you’re pushing the amp too hard.

High level inputs let you connect it to a factory radio without a separate line output converter, and the built in RGB LED lighting adds a clean custom look to your install.

For full rated power, plan on upgrading your electrical system. B2 recommends a dedicated battery for this amp, especially when running it at 1 ohm.


Features



  • Dimensions: 13.77" L x 5.43" W x 2.48" H (350 x 138 x 63 mm); measure your mounting spot and leave room for wiring and airflow

  • Power input takes 1 gauge wire with a recommended 200A fuse

  • Minimum load is 1 ohm; running below that can cause overheating and voids the warranty

  • B2 recommends a dedicated AGM battery of at least 150 Ah and 2000 CCA, or a 30 Ah lithium battery (6C), to get full rated power

  • The subsonic filter cuts frequencies below your setting, which helps protect subs in ported boxes from over excursion below the box tuning
