Installation Precautions/Hints
Do not mount the OVERDRIVE PLUS Line Driver where it will be ex-
posed to outside elements or extreme temperatures. Avoid areas of severe
vibration or shock, and never drill into a car panel without knowing what’s
behind the panel. Think safety at all times.
• Mounting the OVERDRIVE PLUS as close to the head unit as pos-
sible sends the maximum signal down the wire so you hear more music
and less noise.
• Use high quality, 100% shielded audio cables.
• Plan on a single-point ground scheme so all components, including
the head unit, connect to a common ground point. Clean off all paint to
bare metal at the ground point and use a star washer. Use no less than 14
gauge wire for the power and ground connections.
Set-up
Review the Level Matching section on page 7 of this manual. Level
matching is what will allow you to get all the performance your OVER-
DRIVE PLUS is capable of.
• Turn down your amp gains to their minimum setting, as well as the
gains of any other components coming after the OVERDRIVE PLUS.
Then you can run a higher signal (better signal to noise) into the ampli-
ers. Don’t worry, your amps will still go to full output with the signal they
get from the OVERDRIVE PLUS.
• Adjust the OVERDRIVE PLUS for the maximum output that the next
component in the chain can handle. The Tech Videos and Tech Notes in
the support section of www.audiocontrol.com will take you through the
level matching procedure. Note: Make certain that whatever component
you put after the OVERDRIVE PLUS can withstand the output voltage
you dial up. The inputs of many crossovers and ampliers will clip around
2 volts. All AudioControl products can handle inputs of 9 volt RMS.
