4.1 Remove all necessary parts to gain access to the rear of the factory head unit. The
method of disassembly varies for each vehicle. If unsure, please contact Beat-Sonic
for advice for vehicle specific instructions.
4.2 Viewing the head unit from the rear, locate the leftmost 28-pin connector and the
adjacent 10-pin connector. Disconnect the leftmost 28-pin connector and 10-pin
connector from the back of the factory head unit and connect the PA2T3K connectors
inline with the factory connectors in a daisy chain configuration (see section 3).

■ Features
- Designed for Toyota 28-pin / 10-pin radio connectors
- Class AB high efficiency car audio amplifier
- Easy to install plug & play installation
- Retains factory head unit, speakers and connectors
- Manufactured using premium hi-fi audio grade components
- Made in Japan
■ Important
- This product is installed using the factory harness connectors, however there are multiple
factory harness connectors of the same size and shape. Do not plug into the wrong connector
or serious damage may result. Contact Beat-Sonic if unsure.
- Check the Beat-Sonic website for the latest vehicle compatibility information before installing.
- Some vehicles may require extensive disassembly to install this product. Installation should be
performed by an experienced motor vehicle technician or auto electrical professional.
■ Protection Circuit
■ Contents
■ Precautions
- This amplifier is suitable for negative ground 12V DC operation only.
- Wrap cables in protective electrical tape when routing near metal brackets and sharp edges.
- Do not install main unit or harness near moving mechanisms such as the steering column,
seat rails, pedals etc.
- Do not install this product where it may get wet or in areas where it is likely to get dusty or dirty.
- Do not open, disassemble or modify this product.
- Ensure the car battery is in good condition. A weak battery will cause a significant drop in
power output and sound quality.
This amplifier is provided with a protection circuit that operates in the following conditions:
- When the speaker output terminals are short circuited
- When the battery is connected in reverse polarity
- When the amplifier is overheated
If this occurs, turn off the ignition and determine the cause of the malfunction. In case of
overheating, wait until the amplifier has cooled off before using.

PA2 Amplifier
3.5mm to RCA cable
The PA2 is provided with 4 channel line level (RCA) inputs. These inputs can be used
to connect an additional audio source device that can be played either simultaneously
or separately to the high level inputs from the factory head unit.
As an example, the headphone output (3.5mm) from a smartphone can be connected
to the RCA inputs on the PA2 amplifier by using a 3.5mm to RCA cable together with
2 x RCA splitter cables.
*3.5mm to RCA cable and RCA splitter cables are sold separately and are not included.

4.4 Decide a suitable location to mount the PA2 amplifier. The mounting location will
vary depending on the vehicle. Suggested mounting locations include behind the
factory head unit, inside the glove compartment, behind the glove compartment or
under the passenger seat.
i) If installing behind the factory head unit, behind the glove compartment or other
location inside the dash, use the use the supplied foam padding strips by cutting
to size to insulate against possible rattles from metal to metal contact.
ii) If installing inside the glove compartment, use the provided double sided tape
strips to secure the amplifier in place. An opening may need to be cut into the
top/side of the glove compartment to allow the cables to pass through. Before
installing, confirm the glove compartment can be freely opened and closed with
the amplifier in place, and the cables do not obstruct moving parts.
iii) If installing under the passenger seat, first confirm the cable length will reach the
desired location under the seat. After confirming, attach the supplied carpet
mounting tape to the underside of the PA2 amplifier. The carpet mounting tape
will grip the carpet and hold the amplifier in place.
4.5 Route the PA2 wiring harness to the location of the amplifier and connect both the
16-pin grey connector and 8-pin white connector to the amplifier.
4.6 Confirm all connectors are fully inserted before reinstalling the head unit back into
it’s original position. Test the system by turning on the radio and confim that sound
is output from all speakers. Play music through the sound system and adjust the
gain if necessary (see section 5 below).
4.7 Return panels and trim to the original locations taking care to ensure all connectors
are reconnected to complete the installation.

Gain Adjustment
5
Gain adjustment allows optimization of the factory head unit volume range in relation to
the amount of power output by the PA2 amplifier. In most installations, the gain on the
PA2 amplifier can be left at the factory set 50% gain (approx. 12 o’clock) position. In
some cases however, adjustment may be necessary to prevent overdriving the speakers
at relatively low volumes.
It is important to remember that a lower gain setting does not mean less available power
- it just means that the head unit volume needs to be increased to deliver the same
output volume.
5.1 Adjust factory head unit bass, treble, balance and any other equalizer settings to the
mid point positions.
5.2 Play music with impactful bass, treble and vocals. Slowly increase the volume on the
factory radio to a medium-high level while carefully listening for any distortion. Use your
finger nail or small flat head screwdriver to adjust the gain on the front and rear channels
for maximum volume without distortion or overdriving the speakers.

How to Adjust the Gain
The gain control will turn easily until the maximum or minimum stop position is reached.
Do not forcibly turn the gain beyond the max / min stop position otherwise damage can occur.

Check battery voltage (11V ~ 15V).
Vehicle uses digital accessories
(ACC) mode.
Certain vehicles, notably Toyota ZN8 GR86 & Subaru
ZD8 BRZ use digital ACC mode. Place vehicle into IGN
mode to turn on the amplifier. This is unique to the
vehicle and is not a defect.
Head unit volume is too low or
fader is biased to front or rear.
The gain setting is not adjusted
correctly.
Adjust volume on radio. Check fader settings are set to
neutral.
Adjust gain settings as explained in section 5 of this
manual.
Head unit volume is too high or
fader is biased to front or rear.
The gain setting is not adjusted
correctly .
Vehicle uses factory 2ch input
amplifier.
Adjust volume on radio. Check fader settings are set to
neutral.
Adjust gain settings as explained in section 5 of this
manual.
Adjusting rear gain
has no effect on
music volume
Keep rear gain at 12 o'clock (default) position. PA2 will
provide maximum power to the factory amplifier using
the front 2 channels.
The amplifier gets
abnormally hot
Speaker impedance is too low.
Inadequate ventilation.
Use speakers with suitable impedance 4 ~ 8Ω.
Make sure amplifier is installed in a well ventilated
location.
