INTERCONNECTION

BEFORE CONNECTING

For the professional installation of a sound system, car audio retail stores offers appropriate wiring kits. Ensure a sufficient profile section (refer to the table below) and a 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.

FUSE
The inserted fuses (2 x 40 A) are protecting the amplifier from shorts and capacity overload. If you need to replace the fuse, make sure to use the same type of fuse with the same rating.

POWER
Connect the POWER + terminal with the +12V pole of the vehicle’s battery. Use a suitable cable with a sufficient cross-section (refer to the table below). Connect the POWER 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 (refer to the table below) and the same size like the +12V power supply wire

ADDITIONAL CABLE FUSE (NOT INCLUDED)
Install an extra fuse (not included) for the +12V power cable near the battery to secure the power cable. The distance between the fuse and the battery should not exceed 30 cm. The fuse size must be adapted to the cable cross- section of the installed power cable (see table below).

IMPORTANT : The fuse on the battery does not protect the amplifier, but the cable between the battery and the amplifier against short circuits.

Recommended minimum cable cross-section to guarantee full amplifier performance:

• Up to a length of 3 m: 20 mm2 / Full OFC cable
• From a length of 3 m: 25 mm2 / Full OFC cable
