Engineered Power. Elevated Performance.
Aura introduces its latest innovation in high-fidelity car audio: a Class AB amplifier purpose-built for 24V systems under the bold and reliable Fireball Series. Designed to combine raw power with refined audio control, this amplifier is tailored for demanding automotive environments such as trucks, buses, and commercial vehicles running on 24V power architecture.
Power That Performs
Delivering stable and dynamic power across multiple load conditions, the Aura Fireball Class AB amplifier provides:
- 125W x 4CH @ 2 Ohms
- 101W x 4CH @ 4 Ohms
- 250W x 2CH @ 4 Ohms (Bridged Mono)
All outputs are measured at 14.4V with <1% Total Harmonic Distortion (T.H.D.), ensuring clear, distortion-free playback and consistent high-performance output.
Note: Although the amplifier operates on a 24V system, power ratings are standardized at 14.4V for audio specification compatibility.
Precision Audio Control
This amplifier offers comprehensive sound shaping capabilities:
- Low Pass Filter: 50Hz–250Hz
- High Pass Filter: 40Hz–3kHz
- 12dB Crossover Slope for smooth signal transition
- Bass Boost for enhanced low-frequency response
It supports both unbalanced RCA inputs (Tiffany-style) and high-level speaker inputs, making integration easy across OEM and aftermarket setups. The input sensitivity of 6V accommodates high-voltage sources without compromising signal integrity.
Built to Withstand, Designed to Perform
Featuring a 2-layer red PCB, the Fireball amplifier is engineered for durability, thermal efficiency, and clean circuit layout. Its high/low voltage protection range (9–24V) ensures safe and stable operation in commercial and heavy-duty vehicle applications. A REM turn-on trigger provides easy system activation, and the POWER LED status indicator offers real-time operational feedback.
With an idle current of 0mA, the amplifier conserves energy when not in use, and a signal-to-noise ratio exceeding 95dB guarantees crystal-clear playback even at high output levels.
Why Aura Fireball?
- Purpose-built for 24V electrical systems
- Class AB topology for warm, dynamic sound
- Efficient, robust, and installation-friendly design
- Perfect for commercial vehicles, RVs, or high-end 24V car audio systems
