Installation Planning And Considerations - Clarion XC7420 Owners & Installation Manual

GENERAL FUNCTION EXPLANATION - CON'T
USB Connection Port
When connecting your Windows (7, 8 or 10) Laptop or Tablet computer to the amplifi er for
tuning, please connect the included 6' USB cable to this port. It is recommended to power
the computer from a battery source to completely eliminate the chance of a ground loop
on this connection. If you require more cable length, purchase a longer cable. Do not use
an extension. You will need a Type A to Type Mini-B USB cable. Use as short a cable as
possible for maximum reliability.
XC-Tune Bootloader Activation Switch
This microswitch is used to put the amp into Bootloader mode. The latest version of the
XC-Tune software will automatically put the amplifi er into Bootloader mode to perform
software updates. It is unlikely that this switch will need to be used.
BC2 Remote Level Control Installation
Clarion includes a remote level control called the BC2 with the XC7420. The function of
the BC2 is programmable in the XC-Tune software. You can adjust the operating range of
the control and which channels the control adjust. Please refer to the XC-Tune section of
this manual for details.
The BC2 can be easily disassembled for custom installations. Please ensure that the
contacts on the circuit board never come in contact with any metal surfaces in the vehicle.

INSTALLATION PLANNING AND CONSIDERATIONS

Clarion XC7 amplifi ers are designed for installation in vehicles with 12V electrical systems
and a chassis ground confi guration. While Clarion strongly recommends professional
installation of our products to maximize the performance of the product, installing the
amplifi er yourself can certainly produce impressive results. Please take into consideration
the following when planning your installation.
• Take care in choosing a mounting location for the amplifi er. Clarion does not
recommend mounting an amplifi er to a subwoofer enclosure. Vibration could damage
internal components of the amplifi er.
• Ensure that the screws used to mount the amplifi er will not damage anything
underneath or behind the mounting location such as interconnects, speaker wires,
factory wiring harnesses, computer modules, factory fl uid lines, fuel tanks and more.
Mounting hardware should be suffi cient to ensure that the amp will not come loose in
the event of a vehicle accident.
• All wiring running to and from the amplifi 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 Amplifi 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.
