01Overview

Top-of-range monoblock for extreme multi-sub builds and strapped-pair setups.

The OGS4500A.1D sits at the top of OG Audio's Class D monoblock range, rated at 4,500W RMS at 1 ohm, 2,900W RMS at 2 ohm and 1,600W RMS at 4 ohm. For the heaviest builds, strap two units for 9,000W RMS at 2 ohm; the hardware is included. A damping factor over 200 and THD under 0.10% keep the output controlled, while 0–9 dB bass EQ, 0–180 degree phase control and a remote level control handle the tuning. Plan around its 450A fuse rating, or 900A when strapped.

Questions

Reach the OG Audio team for product questions, order support, warranty claims, and tuning help.

4,500 W RMS at 1 ohm, 2,900 W RMS at 2 ohm and 1,600 W RMS at 4 ohm. It is 1 ohm stable, so wiring to a 1 ohm final load reaches the full 4,500 W.

Two strapped units deliver 9,000 W RMS at 2 ohm, and the strapping hardware is included. The recommended fuse rating rises to 900 A when strapped.

450 A is the recommended fuse for one amplifier. Plan the dedicated power run around it, and confirm your battery and alternator can supply the current at full output.

High-level speaker and RCA inputs accept 0.2–6 V, so a factory radio or an aftermarket source connects. Tuning covers a 35–250 Hz low-pass, 10–50 Hz subsonic, 0–9 dB bass EQ and 0–180 degree phase.
