Rockford Fosgate Power T15kW Installation & Operation Manual page 11

Example 3:
Four sets of component speakers in parallel on channels 1 and 2.
Six dual 4-ohm voice coil subwoofers in series-parallel combination
to channels 3 and 4 bridged. This provides the amplifier with 1-ohm
stereo loads on channels 1 and 2 and a 1.5-ohm bridged load on
channels 3 and 4.
In this configuration the amplifier will provide 2000 Watts per
channel on channels 1 and 2 (500 Watts RMS to each component
speaker) and 5333 Watts on the bridged channel 3 and 4
(889 Watts RMS to each of the subwoofers).
As illustrated, many combinations are possible. It is important to
keep in mind that the T15kW is powerful, very powerful, and
selecting the proper combination of speakers and the load it
presents to the amplifier is crucial in preventing speaker overload
and possible damage to the speakers.
