Description

Sundown Audio SAEv4-5000.1D

SAEv4‑5000.1D is a mono‑block Class‑D amplifier designed for heavy‑duty subwoofer and SPL (sound pressure level) car audio systems. It delivers very high RMS power even at low impedance — built to drive powerful subwoofers with clean, controlled output. The amp includes adjustable low‑pass and subsonic filters, phase shift control, and robust protection circuitry (thermal, voltage, speaker‑short, DC‑offset) for reliable performance under demanding loads. A heavy aluminum heat sink ensures thermal stability, and a wired remote control with clipping indicator is included so you can monitor output and clipping status.

Questions and Answers

Q1: What power output does SAEv4‑5000.1D deliver?

A1:

  • 5000 W × 1 channel @ 1 Ω RMS

  • 3300 W × 1 channel @ 2 Ω RMS

  • 2200 W × 1 channel @ 4 Ω RMS

Q2: What type of amplifier is it and what load is it stable at?

A2: It is a mono Class‑D amplifier, and it is stable down to 1 Ω  suitable for low‑impedance subwoofer loads.

Q3: What filters and tuning options does it come with?

A3: It includes a variable 12 dB/octave low‑pass filter (40–180 Hz), a variable 12 dB/octave subsonic filter (10–40 Hz), and a phase shift control (0–180°) — useful to tune bass/subwoofer output precisely.

Q4: What protections and safety features does it have?

A4: The amp includes full 4‑way protection — thermal protection, over/under-voltage protection, speaker‑short protection, and DC‑offset protection. It also has indicators for power, clipping, and protection status.

Q5: What are its general specs regarding input, wiring/installation, and dimensions?

A5:

  • Input sensitivity: up to 6 V max.

  • Operating voltage: DC 10.5 V – 15.5 V.

  • Recommended fuse configuration: 2 × 250 A (total) for proper safety and power delivery.

  • Recommended wiring gauge: 1/0 AWG power wiring (to support high current draw)

  • Dimensions: 18.5″ (L) × 6.3″ (W) × 2.75″ (H)
