Aura Car Audio Fireball 496 Amplifier

Product Overview

The Aura Fireball 494 (also listed as Fireball 496) is a robust 4-channel Class-AB power amplifier engineered to bring serious loudness, dynamic depth, and acoustic warmth to your vehicle's sound system. Whether driving high-power door components or bridging two channels to power a subwoofer, the Fireball 494 provides the clean headroom needed to eliminate distortion at higher volumes.

High RMS Output Class-AB Architecture

Unlike underpowered entry-level amplifiers, the Fireball 494 packs a real punch—delivering a continuous 100 Watts RMS x 4 at 4 Ohms and 150 Watts RMS x 4 at 2 Ohms. Its Class-AB design ensures smooth, musical sound reproduction across the full frequency range, providing crisp highs, rich mid-range vocals, and authoritative mid-bass attack.

Multi-Channel Flexibility & Bridgeable Design

Need versatility for a complete system upgrade? The Fireball 494 can be operated in 4-channel, 3-channel, or 2-channel modes. Bridge channels 3 and 4 to output 300 Watts RMS x 1 @ 4 Ohms to drive a subwoofer while running channels 1 and 2 to power your front component or coaxial speakers.

Precision Electronic Crossovers

Fine-tune your audio staging effortlessly with the onboard active crossover filters. The amplifier features a wide High-Pass Filter (HPF 50Hz – 3kHz) to protect front door speakers from bottoming out, a Low-Pass Filter (LPF 50Hz – 250Hz) for subwoofer duty, and a rear-channel Bass Boost switch (0/6/12 dB) to dial in extra low-end impact.

Frequently Asked Questions (FAQs)

Q: Can I use the Aura Fireball 494 to power both door speakers and a subwoofer simultaneously?

A: Yes! You can configure the Fireball 494 in 3-channel mode. Use Channels 1 and 2 to deliver 100W RMS x 2 to your front left and right speakers, and bridge Channels 3 and 4 to deliver 300W RMS x 1 @ 4 Ohms to power a subwoofer.

Q: What power wiring kit is recommended for this 4-channel amplifier?

A: Because this amplifier outputs up to 400W–600W total RMS power, a 4 AWG (American Wire Gauge) 100% Oxygen-Free Copper (OFC) wiring kit with an appropriately rated inline fuse is recommended for optimal current flow and maximum thermal safety.

Q: Can this amplifier be connected to a stock factory stereo?

A: Yes. The Fireball 494 accepts input sensitivity up to 6V. If your stock stereo does not have built-in RCA pre-amp outputs, you can connect it using a high-quality Line Output Converter (LOC) to step down the factory speaker signals to RCA.
