Wiring precautions

APX_DPX Amps.qxd 2/6/2008 11:53 AM Page 11

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, brake 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 larger 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 APX2181 and an APX4361, 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.
