Orion Cobalt 2 Channel Amplifier - 750W RMS, Class A/B

In this review of the Orion Cobalt 2 Channel Amplifier the bottom line is clear: this amp is aimed at drivers who want reliable subwoofer power and a straightforward feature set without breaking the bank. The unit's most compelling reason to buy is its combination of Class A/B topology and MOSFET power supply that delivers claimed power levels and a tight low end for car audio systems. The review covers performance, build quality, and useful controls such as the remote bass knob and hi/low level inputs so you can decide if it fits your install and listening goals.

Key Features

• Power Handling: Delivers up to 750W RMS per channel at peak loads for strong bass performance when paired with appropriate subwoofers.
• Class A/B Topology: Provides a balance of sonic warmth and efficiency, helping the amp reproduce low frequencies with control.
• MOSFET Power Supply: Ensures stable voltage delivery under load for consistent output and reduced distortion during demanding passages.
• Remote Bass Knob: Lets the driver adjust bass level from the cabin without changing head unit settings, convenient for varying listening environments.
• Hi/Low Level Inputs: Accepts both speaker-level and RCA signals so it integrates with factory or aftermarket receivers.
• Protection Circuitry: Built-in 2-way protection and thermal protection help prevent damage from overheating or electrical faults.

Who It's For

This amp is best for hobbyist installers and drivers upgrading a factory system who want an affordable, capable multichannel amp for subwoofers and mid-bass. The clear controls like gain and remote bass make it practical for those who want quick tuning without a lot of extra DSP or menu diving.

Listeners looking for extreme audiophile detail, fully featured digital tuning, or the absolute lightest, most efficient Class D designs should look elsewhere. If you need a minimalist power house to push a dedicated SPL build at very high sustained output, a higher-end or specialized amplifier may be a better match.

Pros & Cons

Pros

• Good reported power output that matches expectations for its class, useful for noticeable bass impact.
• Versatile inputs with both hi and low level options make installation flexible in many systems.
• Remote bass control and simple gain/crossover controls let you tune bass on the fly.
• Protection features and MOSFET supply add reliability during heavier use.

Cons

• Not as compact or as efficient as modern Class D amps, so it can run warmer in confined installs.
• Features are focused on power and basics rather than advanced digital tuning or networking.
