REM ( REMOTE )

Connect to sw12V with trigger from head unit.

SPEAKER OUTPUTS 

Amplifier connection to loudspeakers.

Minimum speaker cable is 12 gauge. 

Ref 0.5

 minimum impedance is 1 ohm if used as 

a single unit.

Ref 0.5

 in linked mode offers stable opearation to 

a minimum of 2 ohms.

Anno 

minimum impedance is 1ohms stereo or 

4/2 ohms mono

GND ( GROUND CONNECTION )

For connection to the chassis' ground. 

For optimum performance 0 gauge cable is

recommended.

+12V ( POWER CONNECTION )

For connection to the positive terminal of the 

battery (+12). For optimum performance 

0 gauge cable is recommended.

4. INSTALLATION

  

If you chose to install the 

B2

 series by yourself, please read the owners' manual carefully. 

Before you start your installation, please take all steps into consideration. Otherwise, please go to 

www.b2-audio.com for authorized distributors or contact us directly for support.

4-1. MOUNTING PREPARATION

Disconnect the negative (   ) battery cable before mounting 

B2

 series or making any connections. 

Check the battery and alternator ground (   ) connections. 

Make sure they are properly connected and free of corrosion. Before selecting a mounting location 

for the amplifier, please take cooling and safety into consideration.

4-2. MOUNTING PREPARATION

B2

 amplifiers have been designed with a good heat radiation heatsink to avoid excessive heat 

from the amplifier circuitry. For optimum heat radiation performance, it is recommended to 

find a mounting location that allows for vertical installation of the heat sink fins.

REMOTE LEVEL CONTROL PORT

Connection of external level control.

POWER & PROTECTION INDICATOR

Power BLUE, Green-lit shows correct operation 

Protect LED, RED-lit shows general malfunction, 

faulty connection or thermal protection
