ELECTRICAL INTERCONNECTION
INSTALLATION INSTRUCTIONS
WARNING
The amplifier BRX12000D has due to construction-conditioned reasons no internal fuse-protection. The amplifier must neces-
sarily be fused with an external In-Line-Fuse.
The fuse rating always depends on the total impedance. Please refer to our recommended fuse ratings on page 26.

BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offers appropriate wire kits. Ensure a sufficient profile section
(at least 35 mm
2
), the suitable fuse rating and the conductivity of the cables when you purchase your wiring kit. Clean and remove rust-
streaked and oxidized areas on the contact points of the battery and the ground connection. Make sure that all screws are fixed tight after
the installation, because loose connections cause malfunctions, insufficient power supply or interferences. The BRX12000D amplifier has
two ground and +12V two battery terminals, which due to the high output power all must be connected.

GND
Connect both GROUND terminals with a suitable contact ground point on the vehicle’s chassis. The ground wires must be as
short as possible and must be connected to a blank metallic point at the vehicle’s chassis. Ensure that this ground point has a
stable and safe electric connection to the negative “–”pole of the battery. Check this ground wire from the battery to the ground
point if possible and enforce it if required. Use ground wires with a sufficient cross section (at least 2 x 35 mm
2
) and the same
size like the plus (+12V) power supply wires.
REM
Connect the turn-on signal (e.g. automatic antenna) or the turn-on remote signal of your head unit with the REM-terminal of the
amplifier. Use therefor a suitable cable with a sufficient cross section (0,5 mm
2
). Hereby the amplifier turns on or off with your
head unit.
BATT+12V
Connect all BATT+12V-terminals with the +12V pole of the vehicle’s battery. Use suitable cables with a sufficient cross section
(at least 2 x 35 mm
2
) and install additional in-line fuses for each cable. For safety reasons the distance between the fuseblock
and the battery should be shorter than 30 cm. Do not set in the fuses into the fuseblock until the installation is accomplished.
