Electrical Interconnection - Hifonics ARX3003 Owner's Manual

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 25 mm ), the suitable fuse rating and the conductivity of the cables when you purchase your wiring kit. Clean and remove rust-
2
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.
GND
1
Connect this GROUND terminal with a suitable contact ground point on the vehicle's chassis. The ground wire 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 a ground wire with a sufficient cross section (at least 25 mm
the plus (+12V) power supply wire.
REM
2
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
headunit.
BATT+12V
3
Connect the BATT+12V-terminal with the +12V pole of the vehicle's battery. Use a suitable cable with a sufficient cross section
(at least 25 mm ) and install an additional in-line fuse. For safety reasons the distance between the fuseblock and the battery
2
should be shorter than 30 cm. Do not set in the fuse into the fuseblock until the installation is accomplished.
FUSE
4
The inserted fuses protect the amplifier from shorts and capacity overload. The standard fuse is only suitable for a 4 ohm speaker
load. For a 2 ohm speaker load the current consumption increases by 50% and the fuse(s) may need to be replaced by fuses
with a higher rating.
