4.A secure, clean ground connection is critical to the performance of your Clarion amplifier. Use the shortest ground wire possible and securely connect to the car chassis to minimize resistance and avoid noise problems. Besure to clean off any paint, prior to making this connection.

5.Add an external fuse on the amplifier’s positive (+) power lead and connect it as close as possible to the vehicle’s (+) battery terminal. Use a fuse rated to the total current consumption of the amplifier(s). Adding an external fuse will protect the electrical system from short circuits that can cause a fire.

6.Refer to Figure 6 when making electrical connections. Connect the amplifi- er’s positive (+) lead via a fuse directly to the positive (+) terminal on the bat- tery. Do not connect this wire to the car’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 cur- rent rating. Substituting a higher-rated fuse or a slow-blow type can result in serious damage to the amplifier.

8.Never ground the speakers to the vehicle chassis or body.

9.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.

10.To avoid noise problems, run the amplifier’s positive (+) power lead along one side of the vehicle from 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.

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

12.Excess 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.
