Euphoria XPERT EX100.4 4-Channel Full Range Class D Mini Amplifier (EX1004)

Euphoria XPERT EX100.4 4-Channel Full Range Class D Mini Amplifier (EX1004)

The Euphoria EX100.4 is built for serious sound in places where space is tight and performance still matters. This compact 4-channel Class D mini amplifier is engineered to deliver clean, controlled power for motorcycles and other space-limited setups without sacrificing output or precision.

If you’re running high-performance tweeters, compression drivers, or midranges, this amp is designed to handle them with confidence.

Compact Size, Serious Output

Don’t let the small footprint fool you. The Euphoria EX100.4 measures just 5" long, 5.20" wide, and 2.50" high, yet it packs impressive power into that compact chassis.

At 14.4 volts and 1% THD, you get:

• 4 x 50 watts at 4 ohms
• 4 x 100 watts at 2 ohms
• 2 x 200 watts at 4 ohms bridged

That means you can run a full four-channel setup or bridge it for more output where needed. With a minimum working impedance of 2 ohms stereo, it’s flexible enough for demanding system designs.

Full Range Class D Efficiency

The Euphoria EX100.4 uses high-efficiency full range Class D circuitry to maximize output while keeping power draw under control. That’s especially important in motorcycle and compact applications where electrical systems have limits.

It operates within a working voltage range of 10–16 volts, giving you stable performance across different setups. Efficient design here isn’t just about saving power—it’s about delivering consistent, reliable audio when you push the volume.

Precision Tuning with Adaptive Crossover Technology

Dialing in your sound shouldn’t feel like guesswork. That’s where ACT – Adaptive Crossover Technology – comes into play.

Channels 1/2 and 3/4 both feature:

• Variable high-pass filters from 20Hz to 5KHz
• Variable low-pass filters from 50Hz to 5KHz

You can also configure each channel pair in high-pass, band-pass, or low-pass mode, giving you precise control over how your speakers perform. With a wide 10Hz to 20KHz frequency response, the Euphoria EX100.4 delivers full-spectrum performance and the flexibility to fine-tune your system like a pro.

Built-In Protection and Monitoring

Power is great. Controlled power is better.

The Euphoria EX100.4 includes APC – Audio Protection Circuit – and real-time clipping monitoring to help safeguard your speakers from overdriving and distortion. The SESI – Signal Evaluation Status Indicator – provides insight into signal status, helping you keep your system operating within safe limits.

With a signal-to-noise ratio of < 85dB and a damping factor greater than 57 at 4 ohms / 1KHz, this amplifier is designed to maintain clarity and control, even when you’re pushing it hard.

Designed for Maximum Power Delivery

This mini amplifier doesn’t cut corners when it comes to connections. It features large gauge power wire inputs and direct connect speaker terminals to support maximum power delivery and efficiency.

Integrated cooling fins help manage heat and maintain consistent performance over time. The built-in airflow design keeps the amplifier operating smoothly and reliably when the system is pushed hard.

Power, Precision, and Control in One Compact Package

The Euphoria EX100.4 blends compact design with real output capability. From its 4-channel Class D circuitry and adaptive crossover controls to its integrated protection features and efficient cooling, every detail is focused on delivering clean, controlled sound in tight spaces. If you need a mini amplifier that doesn’t compromise on performance, this one checks the right boxes.
