CONNECTIONS (Fig. 5 - Fig. 8)
Before making connections, be sure to turn the power off to all
audio components. Connect the yellow battery lead from the amp
directly to the positive (+) terminal of the vehicle's battery. Do not
connect this lead to the fuse block.
CAUTION
◆ Caution on connection terminals/parts
• Do not allow other objects (particularly electrically
conductive) to get too close or in contact with any of the
unit’s terminals/parts (power supply, fuse, speaker output
terminal, RCA connector, etc.). Doing so may result in
short circuit or accident.
To prevent external noise from entering the audio system.
• Locate the unit and route the leads at least 10 cm (3-15/16")
away from the car harness.
• Keep the battery power leads as far away from other leads as
possible.
• Connect the ground lead securely to a bare metal spot
(remove any paint or grease if necessary) of the car chassis.
• If you add an optional noise suppressor, connect it as far away
from the unit as possible. Your Alpine dealer carries various
noise suppressors, contact them for further information.
• Your Alpine dealer knows best about noise prevention
measures so consult your dealer for further information.
12 Speaker Output Terminals
Referring to “Cautions on speaker wire connections”, insert the
speaker wire into the speaker plug, which is then inserted in the
speaker output terminal.
Note:
• Fully insert the speaker plug to avoid poor connection, or the
wire coming loose due to vehicle vibration, etc.
• The speaker plug can be connected either way, regardless of
polarity indication.
• Do not connect speaker leads together or to chassis ground.
3 RCA Input Jacks
Connect these jacks to the line out leads on your head unit using
RCA extension cables (sold separately).
4 Pre-Out Jacks
5 Battery Lead (Yellow, sold separately)
Be sure to add a fuse as close as possible to the battery's posi-
tive (+) terminal. This fuse will protect your vehicle's electrical sys-
tem in case of a short circuit. If you need to extend this lead, only
use AWG4 - AWG6 (the wire gauge) for this connection.
6 Remote Turn-On Lead (Blue/White, sold separately)
Connect this lead to the remote turn-on or power antenna
(positive trigger, (+) 12V only) lead of your head unit.
7 Ground Lead (sold separately)
Connect this lead securely to a clean, bare metal spot on the
vehicle's chassis. Verify this point to be a true ground by checking
for continuity between that point and the negative (–) terminal of
the vehicle's battery. Ground all your audio components to the
same point on the chassis to prevent ground loops.
CONNECTION CHECH LIST (Fig.10)
Please check your head unit for the conditions listed below:
(Fig. 10)
a. The head unit does not have a remote turn-on or power an-
tenna lead.
b. The head unit's power antenna lead is activated only when
the radio is on (turns off in the tape or CD Mode).
c. The head unit's power antenna lead is logic level output (+)
5V, negative trigger (grounding type), or cannot sustain (+)
12V when connected to other equipment in addition to the
vehicle's power antenna. If any of the above conditions exist,
the remote turn-on lead of your PDX-1.1000 must be con-
nected to a switched power source (ignition) in the vehicle. Be
sure to use a 3A fuse as close as possible to this ignition tap.
Using this connection method, the PDX-1.1000 will turn on
and stay on as long as the ignition switch is on.
◆ Cautions on Power Wire connections
The power wire cannot be connected until its end has been
stripped. Below explains how to connect the stripped end of the
power wire.
Note:
• Use the supplied hexagon screws for this connection. It is highly
recommended that this be carried out by the dealer.
• If you make this connection yourself, ensure the connection is
correct by following the instructions below carefully.
• Be sure to use the supplied hexagon screws for this
connection.
• For safety reasons, connect the battery wire last.
• To prevent disconnection of the leads or dropping of the unit,
do not carry the unit by the wire.
• Be sure to add a fuse as close as possible to the battery.
Make sure to use a fuse of the correct rating for the power
wire.
1. Check the wire gauge.
Notes:
• Only use AWG4-AWG6 (the wire gauge) for this connec-
tion.
• If in doubt, consult your dealer or Customer Support
regarding correct wire gauge to use.
2. Strip back between 7-10mm (9/32"-3/8") of the power
wire's insulation to expose the conductor.
Notes:
• If the length of the exposed conductor is too short, a poor
connection may occur causing operation failure or sound
interruption.
• Conversely, if the exposed conductor is too long, an
electrical short-circuit may occur.
3. Loosen the unit's wire terminal hexagon screws, and
insert the exposed conductor into the terminal and finally
tighten to secure the connection.
4. Verify that the power wire is connected securely.
◆ Cautions on speaker wire connections
When you connect the speaker wire to the unit, you need to insert
the speaker wire into the speaker plug. Below explains how to
insert the speaker wire into the speaker plug.
1. Check the wire gauge.
Notes:
• The available speaker wire gauge for this unit is AWG8 -
AWG12.
• If in doubt, consult your dealer regarding correct wire
gauge to use.
2. Strip back between 7-10mm (9/32"-3/8") of the wire's
insulation to expose the conductor.
Notes:
• If the length of the exposed conductor is too short, a poor
connection may occur causing operation failure or sound
interruption.
• Conversely, if the exposed conductor is too long, an
electrical short-circuit may occur.
3. Loosen fully the speaker plug's 2 hexagon screws using
the hexagon wrench (small, supplied).
4. Insert fully the exposed conductor of the speaker wire into
the wire terminal hole. Refer to Fig.8.
Notes:
• Insert the speaker wire observing the +/– indications on
the speaker plug. Insert the positive speaker wire into
the positive speaker terminal, and the negative speaker
wire into the negative speaker terminal.
5. Tighten the 2 hexagon screws using the hexagon wrench
(small, supplied).
! Crossover Frequency Adjustment Knob (LP FILTER)
Permits adjustment of the crossover frequency, by rotating the
knob to select any frequency between 50 to 200 Hz as the cross-
over point.
" Subsonic Filter Mode Selector Switch
a) Set this switch to “OFF” when you want to
hear tones not possible when the Subsonic
filter switch is used.
b) Set to “15 Hz” when connected to
subwoofers such as 10 inch (25 cm) bass
speakers, if the sound seems less distorted
at that setting.
c) Set to “30 Hz” when connected to ordinary
speakers (not subwoofers) for instance a
mid bass speaker of 8 inches (20 cm) or
more if the sound seems less distorted at
that setting.
#$ Power Indicator
Lights up when power is on.
Is off when power is off.
SWITCH SETTINGS (Fig. 9)
When making adjustments 8-11 below, remove the hexagon screw
(indicated by ★ in the illustration) using the hexagon wrench
(small,supplied), and then open the control cover.
8 Input Gain Adjustment Control
Set the PDX-1.1000 input gain to the minimum position.
Using a dynamic CD as a source, increase the head unit volume
until the output distorts.
Then, reduce the volume 1 step (or until the output is no longer
distorted).Now, increase the amplifier gain until the sound from
the speakers becomes distorted. Reduce the gain slightly so the
sound is no longer distorted to achieve the optimum gain setting.
Input gain adjustment range varies depending on the setting of
the input gain selector switch (see “9 Input Gain Selector Switch”)
Input Gain Selector Switch setting Adjustment Range
0.1V-1.0V 0.1V-1.0V
1.0V-8.0V 1.0V-8.0V
9 Input Gain Selector Switch
Set this switch according to the head unit’s output level.
Set to the “0.1V-1.0V” position when the output level of the head
unit is 0.1V-1.0V. Set to the “1.0V-8.0V” position when the output
level of the head unit is 1.0V-8.0V.

% Status Indicator
Indication color Status Solution
Blue Amplifier circuit is normal.
Turn off the power supply and eliminate the cause. Then turn on the unit and
verify that the indicator color has changed to blue. If it remains red, turn off the
unit and consult your dealer.
Decrease the vehicle’s interior temperature to a normal level. The indicator color
changes to blue.
Use the correct power supply voltage. The indicator color changes to blue.
If this is objectionable, a SPST (Single Pole, Single Throw) switch,
in addition to the 3A fuse mentioned above, may be installed in-
line on the PDX-1.1000 turn-on lead. This switch will then be used
to turn on (and off) the PDX-1.1000. Therefore, the switch should
be mounted so that is accessible by the driver. Make sure the
switch is turned off when the vehicle is not running. Otherwise,
the amplifier will remain on and drain the battery.
