Daily-driver bass that wires straight into a stock radio's speaker outputs.
The OGS1200A.1D is the 1,200-watt model in OG Audio's amplifier range, a Class D MOSFET monoblock rated at a conservative 1,200W RMS at 1 ohm with over 2,300W of peak. It is 1-ohm stable, so you can wire subwoofers down to a 1-ohm final load and still reach the full rating. A 50–220 Hz low-pass filter and a variable subsonic filter set the edges of the bass band, high-level and RCA inputs take a stock radio or an aftermarket source, and a remote level control is included. Plan the power run around its 120A fuse.
See the full specs→- 1-Ohm Stable PowerRated 1,200W RMS at 1 ohm, with over 2,300W of peak, so low-impedance subwoofer wiring still reaches the full rating.
- Stock Radio ReadyHigh-level speaker inputs sit alongside RCA, so a factory head unit or an aftermarket source can feed it.
- Adjustable Bass BandA 50–220 Hz low-pass filter and a variable subsonic filter set the top and bottom of the subwoofer's range.
- Remote Level ControlThe remote level control is included, so you can trim bass output without touching the amplifier's gain.

Questions

1,200 W RMS at 1 ohm, plus over 2,300 W of peak at the same load. It is 1 ohm stable, so a 1 ohm final load still reaches the full rating.
Yes. High-level speaker inputs sit alongside RCA, so a stock radio's speaker outputs can feed it directly. An aftermarket source connects over RCA.
A 50–220 Hz low-pass filter and a variable subsonic filter set the top and bottom of the bass band. The included remote level control trims output without touching the amplifier's gain.
120 A is the recommended fuse. Plan the dedicated power run around it, and check that your battery and alternator can supply the current at full output before installing.
