SB1-3000D | 3000W Class D 1 Channel Monoblock Car Stereo Amplifier

Power Acoustik SB1‑3000D – 3000W Class D Monoblock Amplifier

The Power Acoustik SB1-3000D amplifier from the Saber Series is designed for audio setups where power and space are equally important. With a compact 5″ wide chassis, this amplifier fits into tight installations without compromising performance. It’s optimized for subwoofer-heavy builds, delivering up to 1000 watts RMS at 1 ohm, with thermal efficiency and protective circuitry that keeps your system stable under pressure.

Built to Handle 1-Ohm Loads with Precision

This is a 1-ohm stable monoblock Class D amplifier, meaning it’s engineered to push serious current while maintaining clarity and efficiency. The MOSFET power supply and audiophile-grade IRTM transistors work together to ensure stable voltage under demanding conditions. It’s the type of amplifier you wire once and don’t worry about—whether cruising, competing, or daily driving.

With 3000W peak output, the SB1‑3000D supports large subs or multiple drivers wired in parallel. For setups that require precise tuning, it features a range of crossover controls and a remote gain module, allowing for real-time level adjustments from the dashboard.

Power Ratings

• 400W RMS @ 4Ω
• 600W RMS @ 2Ω
• 1000W RMS @ 1Ω
• 3000W Max Power Output

Control & Tuning Capabilities

Bass response is customizable thanks to a fully variable crossover section. You’ll find:

• Low-pass filter from 35Hz to 250Hz
• Subsonic (hi-pass) filter from 10Hz to 50Hz
• 0–12dB variable bass boost centered at 45Hz
• Dash-mount gain control module (included)

Whether you're dialing in punch for hip hop or tightening up low frequencies for metal, these controls give you full authority over how your subs behave.

Built for Installers

Its 5″ W × 2″ H × 9″ L form factor lets it fit where full-size amps won’t. This makes it a favorite for under-seat installs, trunk wells, or side panel builds. You’ll also find:

• Military-grade SMT circuit board for durability
• High-level input with signal-sense turn-on for OEM systems
• 8-gauge power and speaker terminals for quick, secure wiring

Protection Circuitry

Keeping your gear safe is non-negotiable. The SB1‑3000D includes built-in protection against:

• Direct short circuits
• Thermal overload
• Current spikes and overdraw
