Refer to Figures 1–3 for connector
locations. All the Power Series
amplifiers will accept up to 4-gauge
power and ground wire.
For power, remote and ground con-
nections, strip off one end of each
jacket to reveal bare wire for inser-
tion into the connectors. Connect a
wire from the GND connector on the
amplifier to the nearest bare-metal
chassis component; scrape away
the paint to ensure good conductivi-
ty. Next, connect a wire between the
BATT terminal on the amplifier and
the POS(+) terminal of the vehicle’s
battery. Pass the wire through a fac-
tory-installed grommet in the fire-
wall, or install a grommet if a facto-
ry grommet is not available.
Connect a wire between the REM
terminal of the amplifier and the
“remote out” or power-antenna lead
on the vehicle’s radio.

P80.2, P180.2, P80.4
All the Power Series amplifiers will
accept up to 8-gauge speaker wire.
Connect the speakers, observing
proper polarity, to the speaker-out-
put connector. The total impedance
of the speaker system connected to
the amplifier when the amplifier is
driven in stereo must be at least two
ohms. 
If you are bridging the amplifier,
connect the speaker wires to the ter-
minals marked “bridged,” observing
proper polarity. The total impedance
of the speaker system connected to
the amplifier must be at least four
ohms in bridged mode. 

If you are running the amp in Tri-
Mode (stereo and mono simultane-
ously), connect the satellite speakers
to the speaker connector as you
would a pair of stereo speakers.
Connect the subwoofer to the termi-
nals marked “bridged” Refer to the
chart above to determine the capaci-
tor and inductor values you’ll need
to route bass signals to the woofer,
and the midrange and high frequen-
cies to the satellite speakers. These
passive crossover components will
also ensure that the impedance of
the speaker system doesn’t drop
below two ohms.

BP150.1, BP300.1
Connect the woofers to the amplifi-
er, observing proper polarity.
Although these amplifiers have a
single channel, duplicate positive
and negative connectors are provid-
ed to facilitate the connection of
multiple woofers.
The total impedance of the speaker 
system connected to a BP Series 
amplifier must be at least 1 ohm.
