INSTALLATION PLANNING AND CONSIDERATIONS CON’T
•
All wiring running to and from the ampli
fi
er should be planned so that it’s route does
not bring it in proximity of any high-current devices or computer modules. This will
help to prevent noise from being induced in the audio system.
• XC7
Ampli
fi
ers incorporate balanced differential inputs. As such, Clarion recommends
the use of twisted pair interconnects to ensure that the signal on the center pin and
shield of the interconnect allow this circuitry to perform to the best of its ability in
terms of rejecting unwanted noise.
•
Although the XC7 ampli
fi
ers are suitable for marine installations, they are in no way
water resistant. XC7 ampli
fi
ers should be mounted in a dry, well-ventilated location.
The marine features of the amp are designed to handle humid conditions commonly
associated with installations in boats.
• Ampli
fi
ers dramatically increase the load on the vehicles electrical system. Please
con
fi
rm that the vehicle battery and alternator are in good condition. Clarion
recommends the use of a heavy duty AGM style battery to increase current delivery
and play time. The use of a high quality, low ESR stiffening capacitor will provide
increased instantaneous current to the ampli
fi
er.
•
Supplying adequate current to your ampli
fi
er may require that some of the factory
electrical connections under the hood of your vehicle be upgraded. The industry
refers to these upgrades as ‘The Big 3’. Performing these upgrades are optional, but
highly recommend. Additional current delivery capability will increase the performance
and longevity of any electrical component you add to your vehicle. These upgrades
include:
- A new ground wire from the engine in your vehicle to the battery ground terminal.
- A new ground wire from the ground terminal of your battery to the chassis of the
vehicle.
- A new power wire from the output of your alternator to the positive terminal of your
battery.
Some vehicles use aluminum or adhesive-bonded connections between body panels
and will not allow adequate current to pass. Clarion recommends that a parallel
ground wire be installed to decrease resistance in the return path. Please see the
Power Connections portion of this manual for details.
INSTALLATION
1. Once a safe and suitable location has been chosen for your ampli
fi
er, remove both
top trim pieces from the ampli
fi
er using a 2mm hex driver. Store the four screws and
trim pieces in a safe location.
2. Locate the ampli
fi
er and mark the mounting hole locations.
3. Remove the amp and pre-drill the mounting holes.
4. Replace the ampli
fi
er and secure with adequate hardware.
5. Replace the upper trim panel and secure.
6. Make all the power, signal and speaker connections to the amp.
7. Complete the remainder of the system installation and
fi
nish tuning the ampli
fi
er and
system
8. Install the lower trim panel and secure.
