SounDigital 800.4 EVO – 800W RMS 4-Channel Amplifier | Compact High-Performance Car & Powersport

Powerful, Compact, and Ready for Real-World Setups

The SounDigital 800.4 EVO 4.0 is a high-performance 4-channel Class D amplifier designed to deliver clear, powerful sound in tight spaces. With up to 800 watts of total output, this compact unit suits cars, motorcycles, boats, and rugged off-road builds where space is at a premium but audio quality matters. The EVO 4.0 series emphasizes efficiency, producing less heat during extended listening sessions while maintaining consistent performance.

Designed for Versatility and Reliability

Engineered for installations that demand a small footprint, the 800.4 EVO fits behind dashboards, in saddlebags, under seats, or in glove compartments. Its aluminum heatsink aids heat dissipation, helping maintain peak performance even on long rides or hot days. Moisture-resistant components and a conformal coating provide resilience in challenging environments, making it suitable for motorcycles, ATVs, boats, and other adventures.

Built to give you control where it matters, this amp includes built-in crossovers and adjustable gain. You can tailor your audio response to emphasize clarity, balance, or bass, and you can bridge channels for higher output to a single speaker or sub if your build calls for it.

• High-efficiency Class D design for cooler operation and longer system life.
• Integrated high-pass and low-pass filters plus gain controls for precise tuning.
• Bridgeable channels enable flexible system designs, from 4-speaker setups to a 2-channel sub arrangement.
• Universal fit across cars, motorcycles, ATVs/UTVs, and marine setups.
• Rugged, moisture-resistant construction to handle tough environments.
• Thermal and short-circuit protection to safeguard your investment.

Real-world use cases bring this amplifier to life: a daily driver with crisper highs and clearer mids, a stealth install on a motorcycle with space constraints, or a boat system that stays reliable in damp conditions. The 800.4 EVO offers headroom for growth—you can start with a modest, balanced setup and expand as your needs evolve—without promising guaranteed results.
