ELECTRICAL  INTERCONNECTION

BEFORE CONNECTING
For the professional installation of a sound system, car audio retail stores offer appropriate wiring kits. Ensure a sufficient profile section (at least 0 5 mm), 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.
POWER Connect the POWER + terminal (+12V) with the +12V pole of the vehicle’s battery. Use a suitable cable with a sufficient cross-section (at least 0 5 mm) and install an additional in-line fuse. For safety reasons the distance between the fuse block and the battery should be shorter than 30 cm. Do not set in the fuse into the fuse block until the installation is accomplished.
Connect the POWER — terminal (ground) 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 electrical 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 0 5 mm) and the same size as the positive + power supply wire. This helps reduce most of the interference than can occur in audio reproduction.
FUSE The inserted fuse (40 A blade) protects 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.

WARNING
Make sure the connection polarity Is as Indicated on the terminals. A misconnection may result in damage to the amplifier. After applying power, waft about 8 seconds before turning the amplifier on.

SYSTEM CONFIGURATION

In order to configure the inputs, amplified speaker outputs and pre-amplified power outputs, EQ, and time delays for the amplifier, it must be interfaced with the PC. When you get to this point you must already be aware of what type of system you intend to set up. In order to avoid complications in preparation, make sure the following points before you start:

• The type of signals that will be assigned to the inputs (e.g.: front left or center or subwoofer, etc.).
• The speakers in the system (e.g.: 3-way front or sub stereo or 2-way rear, etc.).
• If there are passive crossovers that manage groups of speakers (e.g.: 3-way systems with active midrange).
• If you intend to use an external mono amplifier to drive a subwoofer. If you intend to use the amplified outputs of the amplifier bridged (BLT mode) thus increasing the power on the output.

WARNING
Before turning on the system, set the head-unit output level to a lower level (approximately 20% of Its maximum excursion) to avoid damaging the speakers during calibration.
