Autotek 2000W Mono Car Amplifier SM-2000 with Bass Knob

The Autotek SM-2000 is a high-output single-channel Class D car amplifier that delivers up to 2,000 watts peak with a user-accessible bass knob for fast subwoofer level control.

This compact black mono amplifier is engineered to push subwoofers with clean, powerful low-end while keeping heat and noise under control. It combines a low-noise preamplifier section, adjustable crossovers, and robust screw-down terminals so you can tune bass response precisely and secure a reliable installation in a wide range of vehicles.

How much power can this amplifier actually provide?

The SM-2000 uses a Class D topology and is rated up to 2,000 watts peak output, optimized for mono bridging and stable into a 4-ohm load. That peak capability gives headroom for brief transients while steady RMS performance drives subwoofers effectively when matched with proper wiring and capacitors.

• Class D efficiency for higher power with less heat
• Mono (1-channel) configuration designed for subwoofer use
• Stable operation into 4-ohm bridged loads
• Peak vs. continuous (RMS) power should be considered for speaker matching

What bass and tone controls are available for tuning?

The amplifier includes a dedicated bass knob plus electronic crossovers and an onboard equalizer so you can shape low frequencies without needing an external processor. These controls let you dial sub level and cutoff points, giving immediate audible impact or subtle reinforcement depending on the system.

• Front-mounted bass knob for quick level adjustments from the driver’s seat
• 12 dB electronic crossovers to set frequency roll-off
• Onboard equalization for fine-tuning sub response
• RCA inputs and low-noise preamp to preserve signal clarity

Will it run cool and install securely in my car?

Autotek’s Quick Thermal Dispersion aluminum heat sink helps keep the amp cool under load, and nickel-plated brass screw-down terminals secure power, ground, and speaker leads. The combination reduces thermal shutdown risk and simplifies wiring for a stable, long-lasting installation.

• Aluminum heat sink designed for effective heat dissipation
• Nickel-plated brass terminals with screw connectors for strong, reliable wiring
• Low-noise circuitry to minimize distortion during high output use
• Compact chassis fits many vehicle mounting locations

Who is this for? The Autotek SM-2000 is aimed at car audio enthusiasts who want a focused mono amplifier to power subwoofers with punch and control. It suits builders upgrading bass performance in sedans, trucks, and compact cars who need a combination of adjustable tuning, high peak power, efficient Class D operation, and durable installation hardware. If you plan to drive large subs at louder levels or need on-the-fly bass adjustments, this amp provides the tools and connectivity to integrate into most aftermarket systems.
