When the unit does not operate properly,
contact your dealer or the nearest autho-
rized PIONEER Service Station.
About This Product
This product is a class D amplifier for the
subwoofer. If both L (left) and R (right)
channels are connected to the RCA input
of this product, output is mixed because
this product is a mono amplifier.
CAUTION
· Never replace the fuse with one of greater value
or rating than the original fuse. Use of an
improper fuse could result in overheating and
smoke and could cause damage to the product
and injury including burns.
· Use the supplied hexagonal wrench to tighten
screws when fastening wires to the terminal or
when changing the direction of the badge. The
use of a long, commercially available hexagonal
wrench can cause excessive torque to be applied
possibly resulting in damage to terminals and
wires.
WARNING
· Always use the recommended battery wire and
ground wire, which is sold separately. Connect
the battery wire directly to the car battery positive
terminal (+) and the ground wire to the car body.
· Do not touch the amplifier with wet hands.
Otherwise you may get an electric shock. Also,
do not touch the amplifier when it is wet.
· For traffic safety and to maintain safe driving
conditions, keep the volume low enough so that
you can still hear normal traffic sound.
· Check the connections of the power supply and
speakers if the fuse of the separately sold battery
wire or the amplifier fuse blows. Detect the cause
and solve the problem, then replace the fuse with
another one of the same size and rating.
· To prevent malfunction of the amplifier and
subwoofer, the protective circuit will cut the
power supply to the amplifier (sound will stop)
when an abnormal condition occurs. In such a
case, switch the power to the system OFF and
check the connection of the power supply and
subwoofer. Detect the cause and solve the
problem.
· Contact the dealer if you cannot detect the cause.
· To prevent an electric shock or short-circuit
during connection and installation, be sure to
disconnect the negative (­) terminal of the battery
beforehand.
· Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.
· DO NOT allow amplifier to come into contact
with liquids due to, for example, the location
where the amplifier is installed. Electrical shock
could result. Also, amplifier and speaker damage,
smoke, and overheating could result from contact
with liquids. In addition, the amplifier surface
and the surface of any attached speakers could
become hot to the touch and minor burns could
result.

Setting the Unit
Terminal Cover
Before setting up the unit, unfas-
ten the screws with a 4 mm
hexagonal wrench and remove
the terminal cover.
Bass Boost Level Control
You can select a bass boost level from
0, 6, 9 and 12 dB.
For instruction of connecting the bass
boost remote control to the amplifier,
see the "Connection Diagram" section.
MODE SELECT Switch
You can select amplifier's sync mode from
MASTER, SYNC and SYNC INV. Set the
MODE SELECT switch to the MASTER posi-
tion when using one amplifier only. When using
synchronously connecting two or more of these
amplifiers in combination, set the first amplifier
to MASTER, and set the remaining amplifiers to
SYNC or SYNC INV according to the manner in
which they are connected. The only time the
amplifier is switched to the SYNC INV mode is
when amplifiers are synchronously connected
with the ex. bridge.
When switching to the SYNC or SYNC INV
mode, remove the screw and stopper. Remove
the screw and stopper after checking that
connections are correct. See the "Connecting the
Speaker Wires" section for details on the MODE
SELECT switch.
Cut Off Frequency Control
for LPF
You can select a cut off frequency
from 40 Hz to 240 Hz.
Bass Boost Frequency Control
You can select a bass boost frequency
from 40 Hz to 120 Hz with the bass
boost control.

Gain Control
If the sound level is too low, even when the volume of the car stereo used along with this
power amplifier is turned up, turn gain control clockwise. If the sound distorts when the vol-
ume is turned up, turn the gain control counter-clockwise.
· When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL
position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more,
adjust level to match the car stereo output level.
·
For synced amplifier's gain control, see the "Setting the Gain for synced amplifier" sec-
tion.
Power Indicator (Blue)
The power indicator lights when the power is switched on.
BFC (Beat Frequency Control) Switch
If you hear a beat while listening to an MW/LW broadcast
with your car stereo, change the BFC switch using a small
standard tip screwdriver.
Subsonic Select Switch
The subsonic filter cuts inaudible
frequencies below 20 Hz to eliminate
unwanted vibrations and minimize
power loss.
PROTECT Indicator (Red)
This indicates a problem with the amplifier. See the "Troubleshooting"
section on page 17 for details.
HEAT Indicator (Yellow)
This indicates a problem with the amplifier. See the "Troubleshooting"
section on page 17 for details.
