Orion Cobalt Elite CEA650.1D Monoblock Car Subwoofer Amplifier – 650W RMS, 1/2/4 Ohm Stable

Overview

The Orion Cobalt Elite CEA650.1D is a compact Class-D monoblock amplifier built to deliver clean, controlled bass from your subwoofer. It blends efficiency with reserve headroom, designed for daily drivers and custom installations alike. Its poised footprint makes it a flexible upgrade for trunk or under-seat placements while maintaining a refined, low-noise electrical profile.

Power and flexibility

Rated up to 650 watts RMS at 1 ohm, with 500W at 2 ohms and 300W at 4 ohms. This power curve supports single sub or dual sub configurations while keeping performance stable across loads. The result is a robust foundation for bass-driven music without unnecessary heat.

• Stable 1 ohm, 2 ohm, and 4 ohm operation
• Flexible wiring for diverse subwoofer setups
• Efficient Class-D topology reduces heat and drain

Precise tuning at your fingertips

Fine-tune bass with adjustable gain from 200 mV to 12 V, a variable low-pass filter from 50 Hz to 250 Hz, bass boost up to 12 dB, and a subsonic filter from 15 Hz to 40 Hz. These controls let you tailor the response to your enclosure and listening preferences, whether you prefer tight punch or deeper extension.

• Gain range 200 mV to 12 V
• Low-pass 50–250 Hz
• Bass boost 0–12 dB
• Subsonic filter 15–40 Hz

Design and protection

The Class-D design emphasizes efficiency and cooler operation, while built-in protection guards against thermal overload, short circuits, and voltage fluctuations. A MOSFET power supply ensures steady bursts of power and quick response to dynamic music passages.

Installability and control

The slim chassis fits tight spaces in cars, trucks, and SUVs, making installation practical in many builds. A remote bass level control lets you adjust bass from the driver's seat, adding convenience during listening sessions or quick tune-ups on the road.

Real-life use cases

Pair with sealed enclosures for tight, accurate bass or opt for a vented box to extend low-end and feel. The amplifier’s impedance flexibility and tuning options support a wide range of subwoofers and vehicle sizes, from compact sedans to larger SUVs.

What’s in the box

Includes the bass remote control, installation hardware, and all essential wiring harnesses to get you started quickly. The package is designed to help you plan a clean, organized setup with room for future upgrades.
