Competition-tier monoblock with phase and bass EQ to dial in the car.
The OGS3500A.1D is OG Audio's competition-tier monoblock, a Class D design rated at 3,500W RMS at 1 ohm, 2,300W RMS at 2 ohm and 1,200W RMS at 4 ohm. Strap two units together for 7,000W RMS at 2 ohm, with the strapping hardware included. A 35–250 Hz low-pass filter, a 10–50 Hz subsonic filter, 0–9 dB bass EQ and 0–180 degree phase control let you tune the subs to your cabin, and a remote level control comes in the box. The fuse rating is 350A, or 700A strapped.

- Phase And Bass EQ0–180 degree phase control and 0–9 dB bass EQ help blend the subwoofers with your front speakers.
- Wide Filter RangeA 35–250 Hz low-pass and a 10–50 Hz subsonic filter set both edges of the sub stage.
- Firm Output ControlA damping factor over 200, THD under 0.10% and efficiency over 90% at 4 ohm keep the stage clean.

Questions
Reach the OG Audio team for product questions, order support, warranty claims, and tuning help.
3,500 W RMS at 1 ohm, 2,300 W RMS at 2 ohm and 1,200 W RMS at 4 ohm. It is 1 ohm stable, so a 1 ohm final load reaches the full 3,500 W.
Yes. Two strapped units deliver 7,000 W RMS at 2 ohm, and the strapping hardware is included. The recommended fuse rating is 700 A when strapped.
350 A is the recommended fuse for a single unit. Plan the dedicated power run around it, and confirm your battery and alternator can supply the current at full output.
Use the 35–250 Hz low-pass filter, the 10–50 Hz subsonic filter, 0–9 dB of bass EQ and 0–180 degree phase control. A remote level control is included.
