• Delivers compact Class D mono power designed specifically for subwoofer systems.
• Stable to 1 Ω, making it suitable for low-impedance subwoofer wiring.
  
• Uses RCA low-level input for straightforward integration with DSP or aftermarket source units.
  
• Avoids onboard crossover/filter processing to keep system tuning external and controlled.
  
• Aluminium heatsink construction supports thermal stability in tight mounting locations.
  
• IRS 2113S technology is specified for clean, stable power delivery in a compact footprint.

• Single subwoofer systems needing compact mounting flexibility.
• Builds running low-impedance subwoofer loads (down to 1 Ω).
  
• Systems where crossover and sub tuning are handled by an external DSP or head unit.
  
• Straightforward daily-driver installs where space is limited but power is still required.

This one is built around the realities of modern installs: small chassis, proper 1 Ω stability, and power figures that are easy to plan around for a single sub stage. It’s also deliberately light on onboard processing (no active crossover) so it suits builds where the system tuning is handled by an external DSP or head unit, keeping the amplifier’s job simple: deliver consistent sub power without adding extra variables.
