WIRING PRECAUTIONS
Read all wiring precautions. If you are not sure of the connections, contact
your authorized Clarion dealer.
If you are using a source unit, without a remote turn-on lead, the MCD360 can
be turned on with a switched accessory lead. You can find this accessory
power source in the factory harness at the back of the radio. It is the lead that
turns on and off with the key.
1. Before installation, make sure the source unit Power switch is in the OFF
position.
2. Disconnect the negative (-) lead of the battery before making any power
connections.
3. A clean chassis ground connection is critical to the performance of your
Clarion crossover. Use the shortest ground wire possible and securely connect
to the car chassis to minimize resistance and avoid noise problems.
4. Refer to the Figure 3 when making electrical connections. Connect the
crossover’s positive (+) lead via a fuse directly to the positive (+) terminal on
the battery. Use red-insulated 18-gauge (or larger) wire for the crossover’s
positive (+) power lead and the same-gauge black insulated wire for the
ground.
5. To avoid noise problems, run the crossover’s positive (+) power lead and the
amplifier’s positive (+) power lead along one side of the vehicle 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.
6. 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.
7. 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 and amplifiers.
