APPLICATIONS – 1300a AND 1600a

The Reference subwoofer amplifiers are
single-channel amplifiers. There are two sets of
terminals to make it easy to connect multiple
woofers. Either set of (+/–) terminals may be
used when connecting woofers.

To the right are four application diagrams to help
plan your subwoofer system installation.

NOTE: For simplicity, Figures 3 and 4 do not
show power, remote and input connections.

Subwoofers or voice coils connected in series.

Figure 3. Reference 1300a or 1600a amplifier with two
woofer connections.

Subwoofers or voice coils connected in parallel.

NOTE: Minimum impedance of each subwoofer = 4 ohms if
subwoofers are connected in parallel and 1 ohm if they
are connected in series.

woofer connection.

NOTE: Minimum impedance of subwoofer = 2 ohms

INSTALLATION AND SETUP

Refer to the illustrations on the previous pages
for control location.

Reconnect the (–) negative lead to the vehicle’s
battery. Apply power to the audio system and
play a dynamic music track.

SETTING THE CROSSOVER(S)

Determine your system plans and set the
crossover-mode switch accordingly. If your
system design does not include a subwoofer,
set the crossover mode to FULL and skip to
“Setting Input Sensitivity.”

If your system includes a subwoofer, set the
crossover mode to HP (high-pass) for your
full-range speakers. Adjust the crossover
frequency to limit bass, and provide increased
system volume with less distortion.

Mode Switch:

Full: Allows a full-range signal through to the

speakers; can be used with larger full-range
speakers such as 6" x 9"s.
HP: Allows a high-pass signal through to
the speakers; should be used with most
loudspeakers (can protect your full-range
speakers from being overdriven with low
frequencies, one cause of speaker damage).
LP: Allows only bass to pass through to the
speakers; should be selected when powering
subwoofers.

High-Pass Filters: Initially set the crossover­frequency control midway. While listening
to music, adjust the crossover for the least
perceived distortion from the speakers, allowing
them to reproduce as much bass as possible.

Low-Pass Filters: For subwoofers, choose
the highest frequency that removes vocal
information from the sound of the subwoofer.

If using the 475a to drive a subwoofer(s), set
the crossover mode to LP (low-pass) on the
channels connected to the subwoofer.

NOTE: The 1300a, 1600a and the subwoofer
output of the 5350a are low-pass only and
do not have a crossover-mode switch.

SETTING INPUT SENSITIVITY

1. Initially turn the INPUT LEVEL control(s) to
the minimum (counterclockwise) position.

2. On the source unit, increase the volume
control to 3/4 volume. Slowly increase the
INPUT LEVEL control(s) toward three o’clock
until you hear slight distortion in the music.
Then reduce the INPUT LEVEL slightly until
distortion is no longer heard.

NOTE: After the source unit is on, blue LEDs (on
the top panel) will light, indicating the amplifier
is on. If not, check the wiring, especially the
remote connection from the source unit. Also
refer to “Troubleshooting.”

REMOTE LEVEL CONTROL

The 1300a, 1600a and 5350a include a remote
level control. This will allow the subwoofer level
to be adjusted from the listening position.
Connect the remote level control using the
RJ11 jack on the side of the amplifier. Install
the control module in the front of the vehicle
within easy reach of the driver. Both the under­side of the dash and the center console are
suitable locations.

UNDER-DASH MOUNTING

Select a mounting location that allows easy
access to the control while driving. Using the
REMOTE LEVEL control as a template, mark and
drill holes in the mounting surface. Attach the
REMOTE LEVEL control using the mounting
screws provided (Figure 11).

Figure 11. Under-dash mounting of the
REMOTE LEVEL control.

Route the cable behind the dash or other
interior panels and under the carpet. Do not
route the cable outside the vehicle. Connect the
RJ11 cable between the RJ11 receptacle on the
amp and the receptacle on the REMOTE LEVEL
control (Figure 12).

Figure 12. REMOTE LEVEL control electrical
connection.

SETTING THE BASS BOOST

The Bass Boost control will allow you to enhance
the bass output of your system at 50Hz up to 6dB.

AUX OUTPUT

Reference amplifiers (except 5350a) are
equipped with full-range outputs that can be
used to connect additional amplifiers.

STATUS LEDs
Power: Indicates the amplifier is on.
Protection: Refer to “Troubleshooting” for specific

indications.

Figure 13. LED status.

TROUBLESHOOTING

• PROBLEM: No audio (POWER LED is off).

CAUSE and SOLUTION: No voltage at BATT+
and/or REM terminals, or bad or no ground
connection. Check voltages at amplifier
terminals with VOM.

• PROBLEM: No audio (PROTECT LED glows red).

CAUSE and SOLUTION: DC voltage on amplifier
output. Amplifier may need service; see
enclosed warranty card for service information.

• PROBLEM: No audio (PROTECT LED glows red).

CAUSE and SOLUTION: Amplifier is overheated.
Make sure amplifier cooling is not blocked at
mounting location; verify that speaker-system
impedance is within specified limits.

• PROBLEM:

No audio (PROTECT LED glows red).

CAUSE and SOLUTION: Voltage less than 9V on
BATT+ connection. Check vehicle charging system.

• PROBLEM: No audio (PROTECT LED glows red).

CAUSE and SOLUTION: Voltage greater than
16V or less than 8.5V on BATT+ connection.
Check vehicle charging system.

• PROBLEM: Distorted audio.

CAUSE and SOLUTION: Input sensitivity is
not set properly, or amplifier or source unit is
defective. Check INPUT LEVEL setting, or check
speaker wires for shorts or grounds.

• PROBLEM: Distorted audio (PROTECT LED glows

intermittently).

CAUSE and SOLUTION: Short circuit in speaker
or wire. Remove speaker leads one at a time to
locate shorted speaker or wire, then repair.

• PROBLEM: Music lacks “punch.”

CAUSE and SOLUTION: Speakers are not
connected properly. Check speaker connections
for proper polarity.

Service bulletin # INF2008-02 April 2008
To: All Infinity Service Centers
Model: Reference 1300A
Subject: Turn On/Off Popping Sound

In the event you receive a Reference 1300A auto amplifier with the complaint: “There is a popping
sound in the speakers when the unit turns on or off”, perform the following modification.

Synopsis: Change three components with new component values, and one Transistor with another type.
Note: RoHS-rated* de-soldering and soldering equipment will be required.

1) Remove the silver trim panel (see the owner’s manual page 2); unplug the five-pin Molex connector.

2) Remove the bottom cover, (8) Phillips screws.

3) Remove the front & rear side panels, 2.5mm Allen (hex key) screws.

4) Remove all nine steel transistor clamps. The technique is detailed in Infinity Tech Tip #INFTT2008-01.

5) Slide the main PCB out of the heatsink. Locate and replace the following components.

6) Order kit # REF1300Akit2008, which should contain the following components:
C102, 47µf/16V Electrolytic cap; replace with new 100µf/25V cap
C104, 100/16V Electrolytic cap; replace with new 220µf/25V cap
C140, 220µf/16V Electrolytic caps; replace with new 470u/16V cap
Q207 Transistor 2SC8050 NPN TO-92, replace with new 2SK30A JFET TO-92
When replacing capacitors, observe polarity.
(New transistor should be inserted exactly the same way as former one.)

7) Replace main PCB, clamps, Molex connectors, front & rear panels, and bottom cover.

8) Test unit to assure the complaint has been resolved.

Warranty labor rate: MAJOR repair

TECH TIPS

For models: Reference Series 475a,1300a,1600a,5350a TIP# INFTT2008-01

Subject:

How do you remove the heatsink clips on the Reference Series amplifiers to service the main PCB
or replace an output device ?

Solution:

The heatsink clips on the Reference Series may be extracted from the heatsink channel by the
use of a hardened steel tool such as a 9/64” allen (hex key) wrench, and inserting it into the
square hole in the middle of the clip. Enter the hole and press the tool downwards, concentrating
on first one side of the clip; then switch to the other side. The clip should creep out of the slot in
the heatsink. Sometimes a substantial amount of force may be required before it comes out with a
“pop”. To replace, the clip must be hammered back into place, back into the groove, with a
hammer and extension bar, if needed.
