SPEAKER WIRING

The Class "D" amplifier is a SINGLE CHANNEL dedicated subwoofer amplifier. Unlike other amplifiers, the Class "D" operates as a single channel and cannot be bridged. Don't be fooled by the outputs. Two outputs are used strictly for convenience and are paralleled internally on the amplifier. This means that if both outputs are used with one driver each, the amplifier sees the same load as if the same drivers are connected to only one output terminal. See diagram below.
