■ 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.

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 Locate the 10-pin connector and the 6-pin connector on the back of the factory
head unit. Disconnect the 10-pin connector and 6-pin connector from the back of
the factory head unit and connect the PA2T1K connectors inline with the factory
connectors in a daisy chain configuration (see section 3).

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 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 preset maximum gain (approx. 5 o’clock) position. In
some cases however, adjustment may be necessary to prevent overdriving the speakers at
relatively low volumes.
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.

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.
