0. Installation
For safety reasons, the amplifier has to be mounted properly and fixed to
the car´s body. Please fix the device using the screws that come with
your product. Be careful when drilling holes, there might be wires, fuel
lines or the gas tank behind a wall! Never drill holes when you do not
know what´s behind. Never install signal wires close to power cables to
avoid hum and alternator noise is being induced.
1. Connections
Before you make any connections, always disconnect the battery!
1.1 First of all, connect the RCA cables coming from the radio/headunit
to the respective inputs of your amplifier. Always run signal cables in
a distance to power cables and the vehicle´s factory wires to avoid
induction of noise.
1.2 Now the speaker wires must be connected to the respective speaker
terminals. Please make sure to use speakers with the correct imped-
ance! Also make sure to connect all speakers with correct polarity
to avoid phase problems which can spoil the sound of the whole
system.
1.3 Next step is the ground connection. Check for a good grounding
point using your vehicle´s chassis. Make sure that this point has
good electrical contact! Some parts of the chassis might only be
glued and have no contact to battery (-). Run all ground cables of
the system to this point to avoid alternator whine and other noise.
1.4 As the next connection the +12 V cable has to be connected to the
(+) terminal of the battery. Always be careful not to run this cable
around sharp edges, the insulation might be damaged. For holes
always use grommets!
Always use an in-line fuse in the +12 V power cable in max. 12“
from the battery´s + terminal (value must meet the current require-
ments of the whole sound system,minimum value is 80 A).
1.5 The last connection is the remote wire. The headunit must always
be turned off during this connection, as it might be damaged when
remote output is shorted to ground! Now you can reconnect the
battery and insert the main fuse into the power cable´s fuse holder.
Caution:
Both, the +12 V and the ground cable, must have sufficient diameter!
XETEC proposes the following minimum gauges:
Total output power of the system:
Up to 100 W : 6 mm
Up to 250 W : 8 mm
Up to 500 W : 10 mm
Up to 750 W : 25 mm
Up to 1000 W : 35 mm
Up to 1200 W : 40 mm
more than 1200 W : 50 mm
Weaker Cables will reduce the performance of your system significantly,
and may cause damage to your amplifiers. Weak cables also will heat-up!
To stabily your suply against short impulses we recommend a Capacitor
(only wizh integrated protection System) which you can connect directly
to the Amplifiers Power Suply system by using the “EXT Cap Terminals”.
The usage of a Power Capacitor is strongly recommended for that part
of the amp which is suplying the subwoofers. Please also referr to the
installation guide of the capacitors manufacturer.
Caution
Always replace fuses with same value. Higher values may cause damage
to your amplifier, battery or car!
2. First power-on
2.1 Adjust all level controls to minimum
2.2 Turn on the radio at low volume
2.3 Increase the volume and adjust the front speaker’s volume
2.4 Now adjust the volume ratio between front and rear speakers and
subwoofer.
