Ruthless Audio 1500.1 Micro

Description

Don’t let the size fool you — the Ruthless Audio 1500.1 Micro is a full-blown bass amp packed into a chassis barely over a foot long. It delivers a true 1,500W RMS at 1 ohm with exceptional efficiency, making it a strong choice for tight installs, stealth builds, and daily systems that need serious subwoofer authority without a full-size amplifier footprint.

WHY CHOOSE THE RUTHLESS AUDIO 1500.1 MICRO?

• 1,500W RMS @ 1Ω (14.4V) — serious monoblock power from an ultra-compact chassis.
• 84% / 89% / 93% Efficiency — published efficiency at 1, 2, and 4 ohms helps reduce wasted energy and heat.
• 1-Year 1Ω Warranty Coverage — standard manufacturer defect coverage includes operation down to 1 ohm when warranty conditions are met.
• 12-13/16 in. Overall Length — fits in spaces where a traditional full-size monoblock simply will not.
• High-Speed Class-D Architecture — compact, efficient power delivery with strong transient control.
• 10Hz–250Hz Frequency Response — deep low-frequency extension for subwoofer duty.
• 0–180° Phase Control — helps integrate the subwoofer system with the rest of the vehicle’s audio stage.
• 4 AWG Power Inputs / 150A Fuse — straightforward current requirements for a compact 1,500-watt build.

FULL SPECIFICATIONS

SUBWOOFER & ELECTRICAL RECOMMENDATIONS

Use quality 4 AWG OFC power and ground wiring, a properly sized inline fuse, and a short low-resistance ground. The 150A fuse rating means the electrical system still needs to be healthy even though the amplifier itself is compact.

For full-output 1-ohm use, make sure the vehicle’s charging and battery capacity can keep voltage stable. Operation below 11V is not covered under warranty. Calculate the final impedance of the complete subwoofer/voice-coil network before connecting the amplifier.

Give the heatsink airflow. The Micro chassis saves space, but it still needs ventilation when used hard for long periods.

FREQUENTLY ASKED QUESTIONS

Is the 1500.1 Micro warrantied at 1 ohm?

Yes. The standard 1-year manufacturer defect warranty covers operation down to 1 ohm when all Ruthless warranty requirements are met.

How small is it?

The amplifier measures 12-13/16 inches overall, 4-11/16 inches wide, and 2-1/4 inches tall — small enough for many under-seat, behind-panel, and stealth installations.

Do I need upgraded electrical?

That depends on the vehicle and how hard the system is used, but a healthy charging system, strong grounds, quality 4 AWG OFC wiring, and stable voltage are required. At full 1-ohm output, additional electrical reserve may be necessary.

Why are the efficiency numbers important?

Higher efficiency means a larger percentage of the electrical power drawn from the vehicle becomes amplifier output instead of heat. That helps a compact amplifier deliver serious power without requiring an oversized chassis.

What can void warranty coverage?

Warranty does not cover vibration damage, wire or debris inside the amplifier, wiring below the covered impedance, external RCA damage, excessive clipping, or operation below 11V. Full warranty terms apply.
