SPEAKER WIRING
The USB 3000 is a SINGLE CHANNEL dedicated subwoofer amplifier. Unlike other amplifiers, the USB
3000 operates as a single channel and cannot be bridged. Don't be fooled by the outputs. Two out-
puts 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 two same
drivers are connected to only one output terminal. See diagram below.
In both diagrams, the amplifier sees a 2 Ohm load.
