Product Overview
The Ruthless Audio 1500.1 Micro is a compact Class-D monoblock amplifier that delivers up to 1,500W RMS at 1 ohm for a subwoofer system. Its 12-13/16" overall length makes it easier to plan for installations with limited space.
Use the 0–180° phase control to adjust subwoofer alignment with your front stage. The amplifier also offers 10Hz–250Hz frequency response and input sensitivity from 0.2V–6V.
Key Features & Benefits
- Three rated power levels: Choose from 1,500W RMS at 1 ohm, 1,050W RMS at 2 ohms, or 600W RMS at 4 ohms, each rated at 14.4V.
- Class-D design: The amplifier’s listed efficiency is 84% at 1 ohm, 89% at 2 ohms, and 93% at 4 ohms.
- Phase control: Adjust the phase from 0° to 180° to tune subwoofer integration with your front stage.
- Compact dimensions: The 12-13/16" overall length can help with planning a space-limited installation.
- 4 AWG power input: The specified input gauge and 150A fuse rating provide key details for electrical-system planning.

Why Choose This Product?
This amplifier combines a single-channel subwoofer design with rated output at 1-, 2-, and 4-ohm loads. Its stated 1-ohm stability gives you a lower-impedance option when planning a compatible subwoofer system.
The source recommends pairing it with a high-excursion subwoofer rated for 750W RMS or more. The listed THD is less than 0.01% at 4 ohms, and high-current MOSFETs and thermal management are part of its stated design.
Installation & Compatibility Notes
Plan for the amplifier’s 12-13/16" length, 4-11/16" width, and 2-1/4" height, along with room for wiring and access. The heatsink length is 11-13/16". Check the intended mounting space before installation.
The stated wiring requirement is a 4-gauge power and ground kit with a 150-amp inline fuse. Keep power and ground runs as short as practical. The source recommends an electrical system that can sustain voltage above 13.5V under load and strongly recommends a Big 3 upgrade in 4-gauge or 1/0 AWG for builds running at 1 ohm.
For subwoofer-load planning, the source describes wiring dual 2-ohm voice-coil subs in parallel for a 1-ohm final load, or dual 4-ohm subs in parallel for a 2-ohm load. For ported enclosures, set the subsonic filter to protect the subwoofer from over-excursion.
