B2 Audio Half Bridge Amplifier 1800W 2-Ohm Class-D 4ch RGB LED Lights 1800.4 V2

This Listing Includes

• (1) B2 Audio Riot 1800.4 RGB V2 4 Channel Amplifier with RGB LED Lights

The B2 Audio Riot 1800.4 RGB V2 is a 4 channel Hi-EF Class D amp built on a half bridge design, made to deliver strong, efficient power from a compact chassis. At 14.4 volts, it puts out 4 x 450 watts RMS at 2 ohms and 4 x 300 watts at 4 ohms, or you can bridge it for 2 x 900 watts at 4 ohms.

That gives you plenty of options. Run mids and highs, power an active front stage, or bridge it for subs or high output mid bass. Both the low pass and high pass crossovers adjust from 50 Hz to 5 kHz with a 12 dB per octave slope, so you can dial in each set of speakers right at the amp. High level inputs also let you hook it up to a factory radio without a separate line output converter.

The built in RGB LED lighting has sound activated patterns, or you can turn it off completely for a stealth install.

For full rated power, plan on upgrading your electrical system. B2 recommends a dedicated battery for this amp, especially when running it at 2 ohms or pushing it hard.

Why a Half Bridge Class D Design?

B2 uses a half bridge Class D layout for a good balance of efficiency and durability:

• Less heat, so the amp runs cooler under load


• Lower stress on internal components for better long term reliability


• Efficient use of the voltage your system provides

The result is a 4 channel amp that delivers clean, controlled power day after day.

Features

• Dimensions: 13.03" L x 5.43" W x 2.48" H (331 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 150A fuse


• Minimum load is 2 ohms per channel in stereo and 4 ohms bridged; running below that can cause overheating and voids the warranty


• B2 recommends a dedicated AGM battery of at least 120 Ah and 1500 CCA, or a 20 Ah lithium battery (6C), to get full rated power


• Power, protect and clip indicators let you see at a glance if something needs attention
