Power Connections
Your XC7-Series amplifi er can only produce power if it is fed power effi ciently. Clarion
recommends the use of minimum of 4 AWG copper wire for all power and ground
connections. The use of undersized power wiring may result in damage to your amplifi er.
Clarion also recommends performing “The Big Three” upgrade to your electrical system
when any high power amplifi er is being installed. This includes upgrading the power wire
between your battery and the alternator for both positive and ground connections, as
well as the ground connection between the battery and the chassis and/or rear ground
location.
The amplifi er ground connection is the most important connection in terms of reliable and
effi cient operation of your amplifi er. This connection should be made to a solid and secure
point on the vehicle chassis, or directly to the battery. Do not use a seat or seatbelt bolt
as a ground location. All of the sound deadening, paint and primer must be removed from
the chosen ground location. The ground ring terminal(s) should be secured with a bolt and
locking fastener.
NOTE: Many new vehicles are assembled with extensive aluminum materials, composites
and high strength adhesives. Clarion recommends running a ground wire of the same size
as the power wire from the negative terminal of your battery to the ground location of your
amplifi er. This is known as a parallel ground.
Wiring Precautions
Read all of the wiring precautions prior to making any connections. If you are unsure and/
or don’t have the necessary installation hardware, contact your local Clarion dealer to
perform the installation.
1. Before you begin the installation, make sure the vehicle is not running and is in the
OFF position.
2. Disconnect the negative (-) lead of the battery (or batteries) before making any power
connections.
3. When making connections, be sure that each connection is clean and secure.
4. Insulate connections with split loom or heat shrink tubing where possible.
5. A fuse holder and fuse must be installed on the lead coming from the positive (+)
terminal of the battery. This fuse should located as close a possible to the battery
terminal for maximum protection. Clarion does not recommend the use of a circuit
breaker as a protection device.
6. The battery fuse rating should equal the total current consumption at full output of the
amplifi er(s) connected to that wire. Do not install the fuse until the entire installation
has been completed.
