Budget Audiophile Amp Coming to Car Audio?

Fosy Audio's First Car Amplifier Unboxing and Review

Introduction to Fosy Audio

• Fosy Audio has been recognized for its miniature amplifiers, including mono blocks, stereo amplifiers, preamplifiers, and headphone amps.

• The company is known for providing high-quality components at relatively low prices, making their products popular among consumers.

Overview of the CA30 Car Amplifier

• In February 2026, Fosy Audio launched its first car audio amplifier, the CA30.

• The unboxing includes high-level inputs, Allen keys for installation, mounting screws, and a manual detailing features in multiple languages.

Features of the CA30 Amplifier

• The CA30 is a compact Class D 4-channel amplifier measuring 7.25 inches long by 4 inches wide by 1.75 inches tall.

• It features adjustable crossover settings (low pass/full range/high pass), gain controls for channels one and two, with similar settings available for channels three and four.

• High-level inputs can handle up to 8 volts from speaker levels; however, it lacks a two-channel switch which would allow using only two inputs to drive all four channels.

Technical Specifications

• The amplifier has robust terminals: four gauge for power/ground connections and twelve gauge for remote terminal connections.

• It supports bridging capabilities across two to four channels with ratings of 100 watts at 4 ohms or 160 watts at 2 ohms per channel.

Performance Testing Results

• Initial tests show that the amp delivers close to its rated power output: approximately 99 watts per channel at a certified test with minimal distortion.

• At a dynamic test under similar conditions (2 ohm load), it achieved about 149 watts per channel on average but peaked around 195 watts dynamically.

Bridged Mode Testing

• When bridged into two-channel mode using outer terminals, the amp reached about 323 watts per channel during certified testing.

• Dynamic testing in this mode yielded an impressive output of approximately 395 watts per channel.

Efficiency Ratings

• Overall efficiency ratings were noted as follows: approximately 80% at 4 ohms and around 70% at lower impedance loads.

This structured summary provides insights into Fosy Audio's new product launch while highlighting key specifications and performance metrics relevant to potential users or enthusiasts interested in car audio systems.

Car Audio Review: Fosy Audio CA30 Amplifier

Initial Impressions and Sound Quality

• The reviewer notes that sound quality is subjective but finds the amplifier to have a very low noise floor, indicating no hiss from the speakers.

• The Fosy Audio CA30 features multiple output channels (two, three, or four), a compact design, and high-quality input terminals for power and ground connections.

Internal Components and Design

• To access internal components like fuses, the amplifier must be disassembled; this involves removing screws from various sides.

• Inside the amp are heat sinks and capacitors rated at 35V 1500 microfarads for outputs. The reviewer expresses disappointment in capacitor quality.

• Class D chips (Infinion 4322M) are used in the amp, each rated at 100 watts by two channels.

Pros and Cons of Fosy Audio CA30

Advantages

• Offers flexibility with channel outputs and has an extremely low noise floor while sounding great according to the reviewer's personal experience.

Disadvantages

• Requires four channels of input without Tiffany style RCAs; basic aesthetics; internal fuses can be inconvenient if blown; lower-quality capacitors than preferred brands.

Conclusion of Review Process

• The review is independent and not sponsored by Fosy Audio. Pricing details were unavailable during editing but will be provided later.

• A dynamic test was conducted to check performance under load conditions, revealing over 300 watts output from this small amplifier despite it not being designed for such tests.
