Cables
•
Whenever possible, route power wire and signal wire on opposite sides of the
vehicle. This prevents the signal cables from picking up electrically radiated noise.
•
Protect all wire from damage. Where a power wire passes through the fire wall or
near exposed metal edges, protect the wire with a rubber or plastic grommet. Use
wire loom where possible for further protection.
•
Extra cable can cause signal loss and act as an antenna for noise. Use only high-
quality RCA cables that are no longer than necessary to make a direct connection
with the source unit and amplifiers.
•
Make sure each connection is clean and secure. Insulate final connections with
electrical tape or shrink tubing.
Improper connections may result in
unreliable operation and damage the
amplifier or the vehicle.
Grounding the amplifier
•
A good chassis ground connection is critical
to minimize resistance and avoid noise
problems.
Use the shortest wire possible. Clean off any
paint, primer or sound deading prior to
making this connection.
To minimize resistance and avoid noise
problems, securely connect the ground wire
to the car chassis and the source unit ground. Using existing bolts is not recom-
mended.
•
The last connection you make should be the ground wire at the amplifier. As the
power supply capacitors in the amplifier are not charged, a spark may be pro-
duced when you make this connection.
Use a test light with an incandescent bulb between the ground terminal and the
power wire to charge these capacitors if this is a concern. The ground wire is the
most important connection to the amplifier. Make sure it is both electrically and
mechanically sound.
