INSTALLATION

BEFORE YOU BEGIN THE INSTALLATION

Before you install your s tereo, read all the instructions in this owner’s manual. You should be able to answer all of these questions about your vehicle’s electrical and sound systems:

• Which terminal in my vehicle’s fuse box supplies power even when the ignition is turned off?

• Which terminal in my vehicle’s fuse box is for accessories?

• How do I conn ect a wire to the fuse box?

Also, be aware that installation in your vehicle might require cutting or modifying your vehicle.

Place the stereo as close as possible to the selected mounting location. We recommend that you install the stereo by temporarily connecting it to ground and p ower, optional components, and your speakers. Then test the connections, disco nnect the stereo, mount it in your ve hicle, and reconnect it. The instructions in this manual are arranged in this order.

Routing Sp eake r Wi res

If you install speakers, avoid routing the speaker wires near mo ving parts or sharp edges.

Using an Adapter Harness

If you are replacing an existing stereo, or if your vehicle has been factory-wired for autosound components, you might be ab le to use an adapter harness to connect the power and speakers. RadioShack stores sell adapter harnesses for most vehicles.

Follow the directions that come with the adapter harness to temporarily connect the ground, power, optional components, and speakers. Then go to “Connecting the Antenna” on Page 9.

Connecting Ground, Power, and Optional Components

Follow these steps to connect the supplied harness with the 14-pin connector to ground, primary and memory backup power, and optional components.
