• Total Power (Sum of Rated Power): 1500 Watts RMS total, providing substantial headroom for bass-heavy runs and dynamic bass bursts.
• Rated Power (RMS Continuous Power): 1000 Watts x 1 @ 4-Ohm; 1500 Watts x 1 @ 2-Ohm; 1500 Watts x 1 @ 1-Ohm, showing solid power delivery across common subwoofer impedances.
• Dynamic Power (PVC/PowerCube): 1045 Watts x 1 @ 4-Ohm; 1549 Watts x 1 @ 2-Ohm; 1715 Watts x 1 @ 1-Ohm, indicating peak capability under demanding transient bass.
• Bridgeable: No, designed as a single-channel mono amplifier for straightforward subwoofer amplification.
• Frequency Response: 20 Hz to 250 Hz ±0.5 dB, ensuring tight control over low end without introducing unwanted highs.
• Input Sensitivity: 150 mV to 4 V, accommodating a wide range of preamp outputs for flexible system integration.
• Circuit Topology: Class BD, offering efficient high-current operation suitable for bass-focused installations.
• Efficiency: 86.2% @ 4-Ohm; 74.6% @ 2-Ohm; 63.0% @ 1-Ohm, reflecting better heat management at higher loads and real-world performance in enclosures.
• Total Harmonic Distortion (THD+N): <1.0% at 4, 2, and 1 Ohm, indicating clean bass output under typical operating conditions.
• Signal Input: 1 RCA pair (low level), standard for most head-unit or processor outputs.
• Signal Output: 1 RCA pair passthrough, enabling easy chaining to additional amps if needed.
• Bass EQ: 0 dB to +18 dB at 45 Hz for targeted bass shaping without flatlining dynamic response.
• Infrasonic Filter: -3 dB @ 28 Hz, 12 dB/Octave, helping reduce subsonic rumble and improve speaker protection.
• Low-Pass Crossover: 35–250 Hz, 24 dB/Octave Butterworth, giving precise control over the upper limit of bass signals sent to the sub.
• Remote Controls: Optional Remote Punch Bass EQ (overrides built-in Punch Bass EQ) for convenient adjustments from the driver seat.
• Power Connections: 4 AWG power/ground connectors for solid, low-impedance wiring.
• Speaker Output: Screw terminal barrier strip for secure subwoofer connections and reliable terminations.
• Cooling: Convection heatsink, providing passive cooling to maintain performance without fans in many install environments.
• Operating Voltage: 9–16 VDC, designed for typical automotive electrical systems.
• Recommended Fuse: 200 A (fuse not included), indicating the sizing needed for protection in high-current scenarios.
• Average Current Draw: 100 A (Music), giving a sense of typical draw in normal operation.
• Max Current Draw: 200 A (Sinewave), representing peak demand under extreme transient conditions.
• Suggested Alternator: 100 A, aligning with its high-power, bass-focused role in a vehicle electrical system.
• Dimensions (H x W x D): 2.14 x 8.14 x 14.91 inches (5.42 x 20.68 x 37.86 cm), compact footprint for under-seat or trunk mounting.
• Shipping Weight: 14.35 Lbs (6.50 Kg)
• CTA-2006 Compliant: Yes, meeting industry-standard amplifier performance and safety guidelines.
• Warranty: 2-Year Warranty, providing long-term support for performance-focused installations.
