Subwoofer: 600W at 50V, 2Ω; 300W at 50V, 4Ω; 160W at 50V, 8Ω. Number of Channels: 2.1, left and right channels and subwoofer. ADJUSTABLE GAIN: Digital amplifier board multi level amplification can ensure the signal strength, enough output power, but also fine tune the gain difference between the left and right channels; Change the R, L resistance to change the gain, the greater the resistance value, the greater the gain.
