To obtain the full potential of the amplifier & to minimize failure, it is strongly recommended & necessary to upgrade the stock electrical system.
Ensure the system is in accordance with the full performance of the amplifier. It is therefore essential to read through the whole manual.
Better Bass
Better Bass is our philosophy of adding something extra.
Keep in mind that continious exposure to SPL above 100 dB can seriously
damage your hearing. Today’s high power auto sound systems can easily
produce SPL over 140 dB. Enjoy your music with sense.

Description of Specifications
Stable impedance load of the Quattro is 2 Ohm stereo & 4 Ohm bridged.
Operation below minimum impedance will stress the amplifier & void the warranty.
Excessive heat will also appear at a faster rate and the and the amplifier will go into thermal protection.
Protection can also be caused by the following
* Speaker overload
* Short circuit
* Input Voltage - RCA & Power Supply
The PCB is a Class H design, optimizing efficiency, limiting dimensions & improving performance superior to
Class A/B with the same scale. (Don’t mistake it for a Class D which has less audible qualities compared to Class H).
The optional wired remote only affects CH 3 & 4.
Operational voltage: 10 V ~ 15.5 V.
Operational voltage will also be affected by the load of the amplifier.

Continious thermal mode can cause damage & void
the warranty.
+ 12V (POWER CONNECTION)
Connects to the positive terminal of the battery (+12V).
For specified performance 4 GA cable is required.
Fuses shall be placed within 20 cm / 8” of the battery.
FUSES
The amplifier is fused with 3 x 25A.
Remember fusing has to be done at
the battery as well!
REM (REMOTE)
Connect to switched +12V from
the headunit.
GND (GROUND CONNECTION)
For connection to the chassis’ ground.
Keep as short as possible (< 50 cm / 20”).
Use minimum 4 GA cable for specified
performance.
CAUTION
Installation of the amplifier shall be done in the following steps:
1. Ensure the ground is appropriate, then connected it to the amplifier. 2. Connect the +12V wire, keep in mind this
wire has to be fused at the battery as well. 3. Connect the switched remote. 4. Reattach negative wire (ground) to
the battery. 5. Operation over 15,5 V will cause the amplifier to go into protect & can void the warranty!

Installation
Installation considerations
If you choose to install the amplifier by yourself, please read the owner’s manual carefully.
Before you start your installation, please take all steps into consideration.
If in doubt, please go to www.b2audio.com for authorized distributors / dealers that will be able to
configure your set up & ensure the warranty of your amplifier.
Preparation
Disconnect the negative (-) battery cable before mounting or making any connection.
Check the battery & alternator ground (-) connection. Make sure they are properly connected / dimensioned
& free of corrosion. Before selecting a mounting location for the amplifier, please take cooling & safety
into consideration. Avoid areas with excessive vibration & up side down installation which can damage the amplifier.
Our amplifiers have been designed with a good heat dissipation heatsink.
In order to avoid excessive heat from the amplifier, it is recommended to find a mounting location
that allows for vertical positioning of the heatsink fins.
For safety purposes, install the amplifier in a dry and well ventilated location and make sure no cables
or other harness of the car is interfaced with the mounting location or will present a hazard to the car’s
cables, control cables, fuel lines / tanks, hydraulic lines or other components of the vechicle.
Power connectors
12V (Power connection)
Before mounting the amplifier, disconnect the negative (-) wire from the battery to protect any accidental
damage to the amplifier or the audio system. The amplifier is equipped with 4 AWG power & ground
terminals. It is crucial that all terminals are used with the adequate cable to ensure correct operation.
Connect the power cables to the power terminal labeled as +12V.
The Quattro is equipped with fuses, but the power cable still has to be fused at the battery.
Connect one end of the fuse holder to the power cable and the other end of the fuse holder to the positive
battery terminal within 20 cm / 8’’ of the same cable.
This fuse location will protect the system and the vehicle against the possibility of a short circuit
in the power cable. Make sure that the fuses and the fuse holder is adequate for the desired application.
Once all cables (pos & neg) are connected to the amplifier, then reattach the negative wire to the battery (final step).
GND (Ground connection)
Locate a secure grounding connection as close as possible to the amplifier.
Make sure the location is clean and provides a direct electrical connection to the chassis of the vehicle.
Connect one end of an equal sized cable as the positive cable to the location of ground.
It is important that the ground cable is as short as possible, but no longer than 50 cm / 20’’ at maximum.
Run one end of the cable to the grounding point.
Run the other end of the cable to the mounting location.
Connect the ground cable to the terminal labeled as GND.
REM ( REMOTE CONNECTION )
Run a remote turn on cable from the switched +12V source.
This may be a toggle switch, a relay, the source unit's remote ouput cable or power antenna trigger cable.
Connect the remote turn on cable to the power terminal labeled as REM.

Troubleshooting
The protection circuits of the amplifier prevents severe damages from faulty conditions & improper use.
The protection indicatior will switch on due to short circuit connection & speaker overload, thus the amplifier will be turned off.
Prior to inspecting the occurred problem, turn all levels down & all power off, then carefully check the installation for
wiring mistakes, shorts or faulty ground (GND). If the amplifier shuts down due to excessive heat, the protection indicator will
light up; please allow time for the unit to be cooled off. Before removing your amplifier, refer to the list below and follow the
suggested procedures step by step. If not at ease, contact an authorized installer which can assist you.
AMPLIFIER DOESN’T TURN ON
Measure voltage on the +12V terminal.
Ensure that the remote terminal has min. 13.8 V DC remote connection.
Recheck the ground (GND) connection. Inspect the in-line fuses.
Check the protection LED is not on.
.
PROTECTION LED IS LIT ONCE THE AMPLIFIER IS TURNED ON
Check shorts on speaker wires & the connected load / impedance. Check power cables & GND.
Disconnect the speaker cables and reset the amplifier.
High / Low voltage, operation voltage is 10 V ~ 15.5 V. Voltages beyond this will cause the amplifier to go into protect.
FUSE BLOWING
Measure the speaker impedance & that it is in accordance with the configuration.
Inspect the power cable for shorts along with vehicle chassis.
OVERHEATING
Measure the speaker impedance & that it is in accordance with the configuration.
Check speaker shorts.
Ensure airflow around the amplifier is sufficient & that the amplifier is not installed in
areas of excessive vibration & upside down!
AUDIO OUTPUT INSUFFICIENT - DISTORTED SOUND
Ensure that the gain settings on the amplifier is matched with the output level of the head unit.
Adjust the head unit volume.
Check speaker shorts.
Adjust the crossover frequencies in accordance with the setup.
If no output at all, check the RCA connections & the cable itself.
TURN ON THUMP
Disconnect the signal input to the amplifier, then turn it on and off.
a) If the noise is cancelled, then connect a delay turn on module on the REM wire running from
the source unit to the amplifier.
b) Use another 12V source for REM lead to the amplifier. If the noise is cancelled, use a relay
to isolate the amplifier from the turn on thump.
HIGH HISS-ENGINE NOISE IN SPEAKERS
Ensure that all signal transferring wires (RCA, speaker cables etc) are kept seperately / away from
the power and the ground wires.
Bypass all electrical components between the Head unit and the amplifier.
Connect the Head unit directly to the amplifier’s input. If the noise is eliminated, the unit bypassed
is the one causing the noise.
Remove the existing ground wires for all electrical components installed. Ensure that the point of
ground is 100% metal which has been grinded free of rust, paint etc.
Replace the ground cable from the OEM battery / alternator and ensure it is grounded accordingly.
Test the battery and alternator load (can be carried out by a professional).
Ensure that the vehichle’s electrical system is in a good condition, this includes distributor, alternator,
spark plugs / wires, voltage regulators etc.
