Power Connections
Your amplifi er can only produce power if it is fed power effi ciently. Clarion recommends the
use of at least 4 AWG wire for power and ground connections. 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 in terms of the 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 should be removed from the
chosen ground location and the wire should be secured with a bolt and locking fastener.
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 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.
7. When replacing the amplifi er or power wire fuse, always use one having the same
amperage rating. Substituting a higher rating fuse or a slow-blow type can result in
serious damage to the amplifi er or vehicle.
8. When creating passage holes for power wire, interconnect cables and speaker wires,
use grommets and wire loom to eliminate any sharp edges created during drilling.
This will protect the wire from being damaged and help to prevent a short circuit.
