Speaker Wiring Diagrams - Clarion XC6420 Owner's Manual & Installation Manual

General Function Explanation Con't
Auto Sensing Control Switch
The XC6420 and XC6620 feature an automatic turn-on circuit that will activate the
amplifi er without the need for a connection to the REM terminal. If you are connecting a
wire to the REM connection, set the Auto Sensing Control Switch to Off.
Bass Boost Level Control
This control allows you to add up to 12dB of boost, centered at 45Hz to the audio signal.
This will add impact and depth to the sound of your system. Be judicious with this control,
as it can dramatically increase the current requirements of your amplifi er, drive the
amplifi er into clipping and cause damage to your speakers.
Crossover Function Switch
This switch allows you to set the internal crossover to function in a high-pass or low-pass
mode, or to be shut off altogether for full range speakers or when used with external signal
processors. High-pass crossovers are used on midrange and high frequency speakers to
prevent low frequency (bass) information from damaging them due to excessive excursion
requirements. Low-Pass crossovers are typically used on subwoofers to prevent midrange
and high frequency information from being passed to them. Large drivers are not capable
of reproducing these frequencies accurately.
Crossover Frequency Control
This adjustment allows the use to alter the -3dB frequency of the crossover. The settings
are the same whether the crossover is set to high-pass or low-pass mode. On the XC6420
and XC6620, the crossover frequency is adjustable from 50Hz to 500Hz. The XC6420
includes a x10 multiplier switch which changes the crossover range to 500-5,000Hz.
Remote Turn-On Connection
When +12V is applied to this terminal, the amplifi er will turn on. When installing the
amplifi er with an after market source unit, this wire is typically Blue with a White stripe.
Some OEM source units have a wire that behaves similarly.
Speaker Connections
The XC6420 and XC6620 amplifi ers are capable of driving reactive loads with a minimum
nominal impedance of 2 Ohms when wired in stereo and 4 Ohms when bridged. When
wiring speakers in stereo, the positive and negative leads from the speakers should
connected to the respective channels positive and negative connections. When bridging
the amplifi er to drive a mono load, only the outside terminals should be used. The positive
connection is on the left and negative is on the right. Please refer to the speaker wiring
diagrams for details
Input RCA Connections
The RCA Input connections should be connected
to the RCA Pre-amp outputs of an after market
Red

head unit. If you are using a head unit that only
has speaker level outputs, adapters are included
with each amp. Please wire them according to the

these connectors used to attenuate the signal. Do
not substitute conventional RCA terminals for these or damage may occur.
