You can't unless you have a dual voice coil sub and put each coil per 2 channels bridged which I don't recommend because the gain setting has to be exact. You can bridge 2 channels together for that one sub but you have to see what impedance your sub is at.

What happens if I bridge an amp?

Bridging an amplifier increases the power that can be supplied to one loudspeaker, but it does not increase the amplifier's total available power. Because a bridge amplifier operates in mono mode, a second identical amplifier is required for stereo operation.

Does bridging amp lower ohms?
