Class D mono amplifier for subwoofers

The Orion CBT3000.1D is a single-channel Class D amplifier built to drive subwoofers in car audio systems. It delivers 3000 W maximum peak power and 1500 W total musical watts, with 900 W RMS at 1 ohm and 14.4 V. Frequency response spans 10 Hz to 250 Hz at -3 dB.

Installers who need one powerful mono block

This unit suits installers who want a compact mono amplifier for a single subwoofer stage. It is not for systems that require multiple channels for midrange or tweeters, nor for builds that need amplifier-level outputs for full-range speakers. Buyers without a wired remote bass control requirement can still use the onboard 40 Hz to 250 Hz low-pass filter and 0/12 dB bass boost.

Stable at 1 ohm with 900 W RMS

The amplifier provides 900 W continuous power into a 1 ohm load at 14.4 V, making the 1 ohm stability rating the key figure for matching subwoofer impedance and wiring configuration.

Questions about this item

What limits the CBT3000.1D first when it runs at full output for a long time?

The 1-ohm continuous rating is 900 watts at 14.4 volts, so the thermal protection will engage once that level is sustained.

How much heat or noise does the Class D mono amp produce during all-day operation?

The aluminium chassis acts as a heatsink with no fan listed, so it runs silently while the case dissipates heat.

What must already be in the vehicle for this amplifier to work?

A 10–16 V DC supply, a 200 mV–6 V line-level or speaker-level signal, and a 1-ohm subwoofer load are required.
