Installation - Clarion XC7420 Owners & Installation Manual

INSTALLATION PLANNING AND CONSIDERATIONS CON'T
• Although the XC7 amplifi ers are suitable for marine installations, they are in no way
water resistant. XC7 amplifi 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.
• Amplifi ers dramatically increase the load on the vehicles electrical system. Please
confi 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 amplifi er.
• Supplying adequate current to your amplifi 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.

INSTALLATION

1. Once a safe and suitable location has been chosen for your amplifi er, remove both
top trim pieces from the amplifi er using a 2mm hex driver. Store the four screws and
trim pieces in a safe location.
2. Locate the amplifi er and mark the mounting hole locations.
3. Remove the amp and pre-drill the mounting holes.
4. Replace the amplifi 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 amplifi er and
system
8. Install the lower trim panel and secure.
