Car Speaker

All Radio Shack autosound  systems come with four color-coded speaker
wires.  The following chart shows Radio Shack's standard color codes.

Speaker Terminal                 Wire Color

Left Positive (+)                    Green
Left Negative (-)                    White
Right Positive (+)                   Brown
Left Negative (-)                    Gray

Connect the stereo's speaker wires to your vehicle's speakers using the
color code chart as a guide.

Note:  Other autosound systems are also equipped with four wires but the
       wires may not use the same color codes.  If your autosound is a
       brand other than Radio Shack, check the owner's manual for the
       speaker wire color codes.

Caution:  Do not connect any of your speaker wires to the chassis ground. 
          Use all four wires to connect your speakers to your vehicle's
          autosound system.

Notes:  Be sure that you match the speaker wires to their corresponding
        positive (+) or negative (-) speaker terminals to ensure proper
        phasing.  Improper phasing can cause poor bass response.

        If your speaker system includes rear speakers, the same color code
        applies.

        If your autosound system has a front to rear fader, connect your
        speakers as shown:

MOUNTING YOUR SPEAKERS

Before you mount your speakers, turn on your autosound system to be sure
that you properly connected the speakers.

Note:  If you are unsure about any part of the installation process, we
       recommend that you have a professional install your speakers.

To mount each speaker:

1.  Select a flat area (such as your car's rear deck) for the mounting
    surface.  The surface should be solid enough for you to drill the
    mounting holes.

2.  Use the speaker cabinet's base as a template to mark the desired
    mounting position.

3.  Drill a hole 6mm wide in the center of the mounting position.

4.  Loosely thread the wing nut about halfway onto the bolt with the wings
    facing the bolt's head.  Then, place the flat washer over the bolt.

5.  Place the speaker cabinet in the mounting position, lining up the
    cabinet's mounting hole with the drilled hole. 

6.  From the underside of the mounting surface, insert the bolt through
    the drilled hole and use  a Phillips screwdriver to screw it as far as
    possible into the speaker's mounting hole.

7.  Secure the speaker cabinet by tightening the wing nut.
