Questions
Reach the OG Audio team for product questions, order support, warranty claims, and tuning help.
250 W RMS per channel at 4 ohm and 340 W RMS per channel at 2 ohm. Every channel is 2 ohm stable, so low-impedance speaker loads still draw the full per-channel output.
Yes. Bridged at 4 ohm, it delivers 2 x 700 W, which suits loads that need more than a single channel gives.
The fuse rating is 2 x 40 A, and the power and ground terminals are 4 AWG.
Choose HPF, FULL or LPF mode. The high-pass and low-pass filters run 50–500 Hz, with x10 multipliers reaching 5 kHz, and a remote level control is included.
