Soundigital SD400.4 EVO 4.0 4-Channel Car Amplifier

Four channels. Zero thermal throttling. Pure, uncompromised sound.

Most 4-channel amps sacrifice performance when they heat up — cutting power right when you need it most. The Soundigital SD400.4 EVO 4.0 solves this with patented DTR technology (Dynamic Thermal Recovery), a globally exclusive system that continuously accelerates heat exchange between components and the heatsink, keeping your amp running at peak efficiency no matter how hard you push it.

Why the SD400.4 EVO 4.0 is built different:

• 🌡️ Patented DTR Technology — dynamic thermal recovery keeps efficiency high under load
• 🔊 4 x 100W RMS @ 2Ω / 4 x 66W RMS @ 4Ω — clean, stable multi-channel power
• 🔀 Bridgeable — 2 x 200W RMS @ 4Ω for flexible system configurations
• 📉 Damping Factor >200 — tight, accurate speaker control
• 🎚️ LP/HP crossover at 80Hz (12dB/oct) — precise signal routing
• 📦 Ultra-compact design — 109 × 113 × 50 mm, only 0.46 kg
• 🏆 Soundigital EVO 4.0 line — Brazilian engineering trusted worldwide
