Wiring the Power Connections
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.

Connections
Connections
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-

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.

Setting Input Level
Initially, turn the input-sensitivity
LEVEL control to its maximum
(counter-clockwise) position. Turn
on the source unit and increase the
volume control until it is approxi-
mately three-quarters of maximum-
output level. Slowly increase the
input LEVEL control (clockwise)
while listening to the quality of the
reproduced sound. When you hear
distortion on the music peaks, turn
the LEVEL control back slightly. This
is the maximum undistorted output
level of your system. Turning the
LEVEL control up farther WILL NOT
INCREASE THE OUTPUT POWER
OF YOUR AMPLIFIER! It will only
decrease the amount of volume-
control rotation before the amp is at
full-output power. It will also
increase the amount of extraneous
noise present in your system.

Wiring the Input-Signal
Connections
Connections
Connect a pair of signal cables with
RCA-type ends between the connec-
tors on the amplifier and the RCA-
type signal connectors on the
source unit. If your radio has only
speaker-level outputs, you should
connect them to the speaker-level
input connectors, observing proper
polarity. When using the speaker-
level inputs, it is not necessary to
connect a wire between the
“remote” terminal of the amplifier
and the “remote” lead from the
source unit. The speaker-level
inputs will sense voltage on the
speaker outputs and turn the ampli-
fier on automatically.
If you are installing a P80.4 amplifier
and your source unit has only one
pair of RCA-type output connectors
and a pair of speaker-level outputs,
you may connect the RCA outputs
to a pair of amplifier input channels
(front or rear), and the speaker-level
outputs to the other pair of amplifier
input channels.

System Setup and Adjustment
Refer to figures 1–6 for location of
adjustment switches and controls.
Electronic Crossover and Bass Boost

The electronic crossover can be
selected as a 12dB/oct. high-pass fil-
ter (HPF) 12dB/oct. low-pass filter
(LPF) or it can be defeated (FLAT).
The crossover frequency can be set
at any frequency between 32Hz and
320Hz.

These amplifiers are designed to
drive subwoofers. Consequently, the
electronic crossover is a 12dB/oct.

The BP150.1 and BP300.1 are
designed to provide constant bass
regardless of the position of the
source unit’s front-to-rear fader posi-
tion. Use of this feature requires that
all four inputs are connected to the
source unit as labeled on the ampli-
fier (front, rear, right and left). If your
source unit has only one pair of
RCA-type output connectors and a
pair of speaker-level outputs, you
may connect the RCA outputs to a
pair of amplifier input channels
(front or rear), and the speaker level
outputs to the other pair of amplifier
input channels. If nonfading bass is
not important in your system, con-
nect a pair of inputs, either speaker-
level or RCA-type, to either the front
or rear input connectors on the
amplifier.
