Ampere Audio AA-500.4 700Wx4 Four Channel Car Amplifier – High Power Car Audio Amp

Power Bigger Speakers with Confidence Using the Ampere Audio AA-500.4 4-Channel Amplifier 

When your system demands serious power, an ordinary multi-channel amplifier simply won’t cut it. High-performance speakers, pro audio drivers, and competition-inspired builds require clean, consistent power to perform at their best. Many enthusiasts find themselves limited by amplifiers that run out of headroom, introduce distortion at higher volumes, or lack the tuning flexibility needed to maximize system performance. The Ampere Audio AA-500.4 was engineered to overcome those limitations and deliver the output today's demanding audio systems deserve.

Why More Power Makes a Difference

Speakers perform best when they have adequate power reserves available. An underpowered amplifier can limit output, reduce dynamics, and introduce distortion as volume levels increase. Whether you're powering a set of high-output component speakers, pro audio mids and highs, or a fully active front stage, clean power is the key to achieving maximum performance. The AA-500.4 delivers an impressive 500 watts RMS per channel at 4 ohms, 700 watts RMS per channel at 2 ohms, and up to 1,500 watts RMS bridged. This level of output provides the headroom necessary to reproduce music with authority, clarity, and impact. From daily listening to competition-level demo vehicles, the AA-500.4 provides the power needed to keep your system performing at its highest level.

Built for High-Output Systems

The AA-500.4 was designed for enthusiasts who demand more from their equipment. Built around a high-efficiency Class D architecture, this amplifier delivers substantial output while maintaining excellent efficiency and manageable operating temperatures. Its flexible design allows it to power everything from full-range speakers and component systems to pro audio setups and bridged subwoofer applications. Advanced crossover controls with selectable x1 and x10 multipliers allow for an exceptionally wide adjustment range, giving installers and enthusiasts the ability to fine-tune virtually any speaker combination. Combined with Ampere Audio's Perfect Band-Pass Filter, the AA-500.4 offers tuning flexibility rarely found in amplifiers within its class.

Key features include:

• 500 Watts RMS x 4 @ 4 Ohms
• 700 Watts RMS x 4 @ 2 Ohms
• 1,500 Watts RMS x 2 Bridged @ 4 Ohms
• Full Range Class D Technology
• Perfect Band-Pass Filtering

Advanced Tuning for Maximum Performance

Every system has unique requirements, which is why the AA-500.4 provides extensive tuning capabilities. Adjustable high-pass and low-pass crossovers allow you to precisely control frequency ranges, while the crossover multipliers dramatically expand adjustment possibilities for advanced applications. Whether you're building a dedicated mids and highs system, an active front stage, or a powerful full-range setup, the AA-500.4 gives you the tools needed to achieve optimal performance. Integrated clipping indicators help you monitor amplifier operation and maximize output while minimizing distortion, ensuring your speakers receive clean, controlled power.

Designed to Handle the Demands of Real-World Use

High output requires durability. The AA-500.4 incorporates Ampere Audio's comprehensive 4-Way Protection Circuit to help safeguard the amplifier from thermal overload, voltage irregularities, speaker shorts, and DC offset conditions. Combined with its efficient Class D design, the amplifier is built to perform consistently under demanding conditions. Whether you're pushing pro audio drivers to extreme output levels or building a powerful daily driver, the AA-500.4 delivers the reliability, flexibility, and performance needed to take your system to the next level. For enthusiasts who refuse to compromise, the Ampere Audio AA-500.4 provides the power to make every watt count.
