Speaker connection

1

Never connect the speaker cables with the chassis ground. This may destroy your
amplifier. Check that your speakers are connected correctly which means plus to plus
and minus to minus.
We recommend speaker cable from 2.25 mm to up. The connection ways are shown
in the attachment.

2

BATT+

Battery + terminal. The +12 Volt power cable must be connected with a fuse in line
near the battery + terminal. Please see the table of cable and fuse selection.

3

REM

Remote terminal. The remote cable must be connected with the radio remote terminal
so that the amplifier will switch on and off automatically with the radio.
If there are two or more amplifiers installed together, it might be necessary to add an
additional relay. Please consult your dealer.

GND

4

Chassis ground terminal. The chassis ground cable must be connected very tight on
a nearby massive and electric conductive place.

5

Gain

Gain control regulates the sensitivity of the amplifier to match the signal output voltage
of your source unit. The gain control is not a volume adjustment. Use high quality CD
music and increase the volume of your source unit to 75% of its minimum volume,
set the gain at the minimum and then increase gain slowly (clockwise). Stop at the
first sign of distortion, then lower the gain a little (counter clockwise) to achieve clear
undistorted music at the maximum level.

Remote Bass Level Control

6

When using the remote bass level control you can adjust volume in the driver seat.

RCA audio input

7

These RCA audio inputs connect with your radio RCA outputs. Please use high quality
RCA cables. Keep these cables as short as possible. To avoid electrical disturbances
from your car electronics, route RCA cabloes away from other current carrying cables
in the car. If your radio has only speaker output, you must use a HIGH LOW LEVEL
adaptor.

8

Bridge in

This RCA jack receives signal from the master amplifier when this amplifier is bridged
as slave. DO NOT use input jacks when the amplifier is working as slave. All the
functions will be adjusted by the master amplifier.

9

Bridge out

This RCA output sents out bridged signal to another same Class D amplifier in bridging
configuration.

- 3 -

Low Pass Filter

10

Filter out high frequency that the woofer cannot play. Adjust this knob to match the
woofer's frequency response.

SUBSONIC

11

Filter out unwanted too low frequency. This function will increase the power handing
of your woofer’s. It can adjust the frequency filter from, 10Hz (OFF) to 50Hz.

12

Bass boost Level

Adjust the boosted frequency from 0 ~ 12dB, APSM-1300/APSM-1500’s boosted
frequency is is adjustable.

13

Bass boost Frequency

Adjust the boosted center frequency. The frequency can be adjusted from 30Hz to
80Hz, use combine with bass boost level adjusting.

We recommend you have the installation done by an Authorized Audiopipe Dealer.
Required power, ground wire and proper external fuse as below:

Model

APSM-1300
APSM-1500
APSM-2000

We recommend the fuse should be installed no more than 12 inches from the battery.
The ground wire should be connected directly with the chassis of your vehicle which should
be metal to metal ground point connection. The amplifier must be mounted securely at a
solid, dry and low vibration surface in the trunk or passenger area. Mount the amplifier
in an open air area to insure proper heat dissipation. Mount the amplifier in a place where
can access easily to set the input controllers. Install all amplifier cables as far as possible
from car electrical cables such as the car ignition cable.

IMPORTANT:

When bridging two amplifiers please refer the bridging wiring chart.

•

When bridging two amplifiers you should use same model amplifiers.

•

Please make sure the negative speaker terminal of two amplifiers are connected by the

•

same gauge cables as the positive terminal being used.
DO NOT connect any signal cables with the input RCA jacks when bridged as slave unit.

•

The LPF, Input level and remote functions will be disabled on slave amplifier when

•

bridged.
All the functions of the slave amplifier will be adjusted by the master amplifier.
