Input Select Switch
The X2 450.4 features an Input Select switch to help simplify
installations and system configuration where only one set of
speaker wires or RCA's is available to connect to the amplifier.
When in 2CH mode, the amplifier will feed the signal fed to
CH1 to CH3 and the signal on CH2 to CH4. This has the
same effect as using Y-cables between those channels but
without the added expense or wiring clutter.
When set to 4CH mode, each of the four RCA inputs feeds
directly to their respective output channels.
Power, Ground and Turn On Connections
The X2 450.4 features a terminal block that is designed to
secure 4 AWG power and ground connections to the amp. We
recommend the use of pure copper power and ground wires in
order to achieve the most reliable connections. Also, be weary
of 4 gauge versus 4-AWG wire. The American Wire Gauge
(AWG) is a universal standard that specifies the diameter of
stranded conductors. Wiring that is labelled as '4 gauge' may
not be adequate to supply the amp with the current it requires
to operate reliably and efficiently.
The Turn On input should be connected to the amplifier +12V
DC remote turn-on output of your after-market source unit. In most cases this is a blue wire with a white stripe. Note: On
some source units, there are power antenna AND remote turn-on wires. If you only hear audio when listening to the AM/
FM tuner, your amp may connected to the wrong wire.
Fuses
The X2 450.4 includes a pair of 25 amp ATC/ATO fuses on
the left side of the end-panel. These fuses exist to protect the
internal circuitry of the amplifier from damage and are not a
replacement for a proper fuse at the battery in your vehicle.
Under no conditions should you increase the value of the
fuses used in this location.
If the fuses blow immediately upon insertion, contact your
authorized ARC Audio dealer or the Technical Support
department at ARC Audio for assistance.
Accessing Controls and Mounting Provisions
The X2 450.4 features our Level 1 X2-Series cosmetics. This simple but elegant top cover design is accented with a
diamond cut aluminum badge and a texture coated finish. Removing the four screws in the badge allows users to rotate
the badge to make it look great in any installation. If you desire the old school and elegant black hairline cosmetics of the
XDi Level 2 cosmetics, no problem - the X2 450.4 is upgradable by purchasing the XDI Trim kit.
To access the controls on the top of the amp, remove the four screws in the badge and set them in a safe place. Remove
the badge and set it in a safe place. The amp shroud can now be removed for tuning and installation.
