Questions and Answers

Q1: What is the power output of SAEv4‑2000.1D?

A1:

  • 2000 W × 1 @ 1 Ω (RMS)

  • 1300 W × 1 @ 2 Ω (RMS)

  • 875 W × 1 @ 4 Ω (RMS)

Q2: What amplifier design and protections does it use?

A2: It’s a digital Class‑D mono amp with a dual MOS‑FET PWM power supply. It includes a 12 dB/Octave variable low‑pass filter (40 Hz–180 Hz), a 12 dB/Octave variable subsonic filter (10 Hz–40 Hz), and a 0–180° phase shift control. Built‑in protection circuitry covers thermal overload, voltage irregularities, speaker‑shorts, and DC‑offset. Power, protection, and clipping indicator LEDs are included.

Q3: What are the electrical and installation specifications?

A3:

  • Input sensitivity: up to 6 V max

  • Operating voltage: DC 10.5 V – 15.5 V

  • Recommended Fuse: 180 A

  • Dimensions: approx. 13.98″ (L) × 6.3″ (W) × 2.75″ (H)

Q4: What kind of systems is this amp suitable for?

A4: It’s ideal for subwoofer or bass‑heavy car audio systems, especially where low‑impedance use (1 Ω) is needed to extract maximum power for deep bass. Good for a single powerful sub or dual‑sub setups (depending on wiring/impedance)  provided power wiring and electrical system are properly upgraded to handle high current draw.

Q5: Does it include remote control or tuning controls?

A5: Yes  the amp comes with a wired remote control (with clipping indicator), and has adjustable low‑pass & subsonic filters plus phase shift control to help fine‑tune bass output based on subwoofer and enclosure configuration.
