Electrical connections for the APX400.4M

6.Refer to the Figure 8 when making electrical connections. Connect the amplifier’s positive (+) lead via a fuse directly to the positive (+) terminal on the battery. Do not connect this wire to the vessel’s fuse panel. Use red- insulated 10-gauge (or larger) wire for the amplifier’s positive (+) power lead and the same-gauge black insulated wire for the ground.

7.When replacing the amplifier’s fuse, always use one having the same current rating. Substituting a higher-rated fuse or a slow-blow type can result in serious damage to the amplifier.

8.Make sure that your vehicle’s electrical system (alternator, battery, etc.) is capable of handling the additional load. If you are planning a multi-amplifier system, you may need to add a second battery and possibly upgrade the alternator with a higher-output rated model. Consult your authorized Clarion dealer for recommendations.

9.To avoid noise problems, run the amplifier’s positive (+) power lead along one side of the vessel to the battery. Run the remote turn-on wire and RCA audio cables down the center, and route the speaker wires along the remaining side. If wires must cross, run them perpendicular to each other.

10.When creating passage holes for the power wire, use grommets to eliminate any sharp edges created during drilling. This will protect the wire from being nicked and causing a short circuit.

11.Extra cable can cause signal loss and act as an “antenna” for noise. Use only high-quality RCA cables that are no longer than necessary to make a direct connection with the source unit or equalizer.
