English
• Always use great care when attaching anything to a vehicle! Check clearances on
all sides of the planned installation before drilling any holes or installing any
screws.
• Make sure the holes you plan to drill will not cut into the fuel tank, fuel lines, break
lines (under the chassis) or electrical wiring. Don’t guess. Check first.
Wiring precautions
Read all wiring precautions. If you are not sure of the connections, contact your
authorized Clarion Dealer.
• Do not open the case. There are no user-serviceable parts inside. If you require
assistance, consult your Clarion Dealer or an authorized Clarion Service Center.
Power
• Before you start, make sure the source unit’s power switch is off.
WARNING!
To prevent short circuits during installation, disconnect the
vehicle’s negative (-) battery lead before making any power
connections.
Fuses
• To protect the vehicle from fire or explosion in the event of a collision, add an
external fuse to the amp’s positive (+) power lead and connect it as close as
possible to the vehicle’s plus (+) battery terminal.
Use a fuse rated to the total current consumption of the amplifier. Fuses mounted
near the battery should be ~10 Amps bigger than fuses on the amplifier itself.
If you are using more than one amplifier, add the total current consumption for the
entire system and use the closest available fuse. For example, if you’re connecting
both an APX2180 and an APX4360, install a 100 Amp fuse at the battery.
• Power wire size can greatly affect the performance of your audio system. The
Power wire size table indicates the minimum power wire requirements for proper
operation.
