Description

Sundown Audio SAEv4-3000.1D

SAEv4‑3000.1D is a mono‑block Class‑D amplifier designed for subwoofer applications and high‑power car audio systems. It delivers potent RMS power even at 1 Ω impedance  ideal for demanding subwoofer builds. The amplifier uses a heavy‑duty aluminum heat sink for improved thermal management, includes variable low‑pass and subsonic filters, phase shift control, and built‑in protection circuits (thermal, voltage, speaker‑short, DC‑offset). A wired remote with clipping indicator is also included to let you monitor and adjust bass output.

Questions and Answers

Q1: What is the power output of SAEv4‑3000.1D?

A1:

  • 3000 W × 1 channel @ 1 Ω (RMS)

  • 2000 W × 1 channel @ 2 Ω (RMS)

  • 1300 W × 1 channel @ 4 Ω (RMS)

Q2: What amplifier class/design and features does it use?

A2: It is a Class‑D mono amplifier with a dual MOS‑FET PWM power supply. It features a 12 dB/Octave variable low‑pass filter (40–180 Hz), a 12 dB/Octave subsonic filter (10–40 Hz), and a 0–180° phase shift controller.

Q3: What protections and safety features are built in?

A3: The amp includes 4‑way protection: against thermal overload, over/under‑voltage, speaker shorts, and DC‑offset. There are also power, clipping, and protection indicator LEDs.

Q4: What are the electrical and installation specifications?

A4:

  • Input sensitivity: up to 6 V max.

  • Signal-to-noise ratio: 92 dB.

  • Operating voltage: DC 10.5 V – 15.5 V.

  • Recommended fuse: 250 A.

  • Recommended amplifier wiring gauge: 1/0 AWG (for proper power delivery).

  • Dimensions: approx. 15.51″ (L) × 6.3″ (W) × 2.75″ (H)

Q5: What type of audio setups is this amp best suited for?

A5: This amp is ideal for subwoofer‑heavy car audio builds, especially where low‑impedance (1 Ω) subwoofers are used to extract maximum power and deep bass. It works well for loud SPL systems or bass‑focused sound setups, provided power wiring and electrical system (alternator/battery) are upgraded accordingly.
