Installation Planning And Considerations - Clarion XC1120 Owners Manual And Installation Manual

General Function Explanation Continued
Bass EQ Control
This XC1120 control allows you to add 12dB of boost, centered at 45Hz to the audio
signal. This will add impact and depth to the sound of your system. Take caution with this
control, as it can dramatically increase the current requirements of your amplifi er, drive the
amplifi er into clipping and may cause damage to your subwoofer(s).

INSTALLATION PLANNING AND CONSIDERATIONS

Clarion XC1 Series amplifi ers are designed for installation in vehicles with 12V electrical
systems and a common ground confi guration. While Clarion strongly recommends
professional installation of our products to maximize performance and reliability,
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. Vibrations could
damage internal components of the amplifi er.
• Ensure the screws used to mount the amplifi er will not damage anything underneath
the mounting location. This can include interconnects and speaker wires, factory
wiring harnesses, computer modules, factory fl uid lines, fuel tanks and more.
Mounting hardware should be suffi cient to ensure 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 prevent noise from being induced into the audio system.
• XC1 amplifi ers incorporate balanced differential inputs. As such, Clarion recommends
the use of twisted pair interconnects to ensure 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 Clarion XC1 amplifi ers are suitable for marine installations, they are not
water resistant. They 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.
