Sony XAV-AX7000 Subwoofer Direct Connection
The Sony XAV-AX7000 is the high-powered version of the AX5000 and can be configured to power a small subwoofer with the internal amp. To do this, the front channel output of the amp will be connected to both the front and rear speaker channels and the head unit will be switched to a 2 ohm configuration. Then one of the rear channels are used for powering a 2 ohm subwoofer. Essentially making a 2.1 style sound system.
This makes for a space-saving and perhaps budget friendly way of adding more bass to a standard speaker setup. That being said, peak power remains at around 100W for the mono channel so this is not meant to replace a proper amp and subwoofer combo.
