CONNECTING POWER  

Follow these steps to connect power to the equalizer.  

1.  Disconnect the wire from the vehicle battery's positive (+) terminal.  
    This reduces the possibility of damage to your vehicle's electrical  
    system during installation.  

    NOTE:  You must reset the clock and any other timer/memory devices  
           such as digital tuner memories for the radio, when you reconnect
           the wire after you complete the power connections.  

2.  Connect the equalizer's black (ground) wire to a clean, metal bolt  
    attached to the vehicle's metal frame.  

    NOTE:  Do not connect the wire to a part insulated from the frame by a
           plastic part.  

3.  Connect the red wire with the 1A fuse holder, labeled EQUALIZER POWER  
    LEAD, to the radio/cassette player's switched power lead, or to a  
    terminal in the vehicle's fuse box that turns on or off with the   
    ignition.  

4.  Connect the red wire with the 3A fuse holder, labeled TO ACCESSORY 12V 
    POWER, to the ACC terminal or any other terminal that turns on and off 
    with the vehicle's ignition.  

5.  If you have a power amplifier with a switched power feature, connect  
    the orange wire labeled SWITCHED POWER LEAD to the amplifier's switched  
    power lead.  

    NOTE:  If you do not use this wire, use a wire tie to keep the wire out
           of the way.  

CONNECTING A RADIO/CASSETTE PLAYER  

If the radio/cassette player has RCA-type line output jacks, make the  
following connections:  

1.  Connect the radio/cassette player's left and right output jacks to the  
    equalizer's corresponding left and right INPUT jacks using shielded  
    cables with RCA-type plugs.  

2.  Disconnect the square, in-line connectors in the equalizer's input  
    wiring harness.  

3.  Connect the equalizer's 5-pin plug to the corresponding jack on the  
    radio/cassette player.  

    CAUTION:  If your radio/cassette player's wiring harness (for power  
              and speaker connections) does not match the equalizer's
              harness, you can buy the proper adapter at your local Radio
              Shack store.  

If the radio/cassette player does not have RCA-type line output jacks:  

1.  Be sure the square, in-line connectors in the equalizer's input wiring  
    harness are secure.  

2.  Connect the equalizer's 5-pin plug to the corresponding jack on the   
    radio/cassette player.  

CONNECTING A CD PLAYER  

To connect a in-dash CD player, connect the CD player's left and right   
outputs to the equalizer's corresponding left and right CD INPUT jacks.  
Use shielded cables with RCA-type plugs for the connections.  

To connect a portable CD player, use a patch cord with a 1/8-inch stereo  
plug at both ends.  Plug one end of the cord into the equalizer's CD jack. 
Then, plug the other end of the cord into the CD player's headphone jack.  

You can also connect other audio components that have a 1/8-inch headphone  
jack.  

CONNECTING AN AMPLIFIER  

Your equalizer has three pairs of RCA-type line-level output leads that   
let you connect a front-channel stereo amplifier, a rear-channel stereo  
amplifier, and a subwoofer amplifier.  

NOTE:  The subwoofer outputs on the equalizer are mono.  This lets you use
       one or two subwoofers with your system.  If you use two subwoofers,
       connect both subwoofer outputs to the amplifier's left and right
       inputs.  

Your local Radio Shack store sells the proper amplifiers for this   
equalizer.  

INSTALLING FUSES  

If the fuse in your radio/cassette player is not rated at 3 amps, replace  
the equalizer's 3-amp fuse with one that has the same rating as the radio/ 
cassette player's fuse.  

TESTING THE EQUALIZER  

Before you mount the equalizer, reconnect the battery's positive (+) wire  
and test the entire system.  See "Operation."  

MOUNTING THE EQUALIZER  

After you test the equalizer, mount it as follows.  You can unplug the   
wiring harnesses to make mounting more convenient.  

1.  Using the U-shaped mounting bracket as a guide, mark the locations for 
    the mounting holes.  

2.  Drill 3/16 -inch holes in the marked locations, being careful not to  
    damage anything on the other side of the mounting surface.  

3.  Attach the mounting bracket to the mounting surface using the supplied
    sheet-metal screws.  

4.  Attach the equalizer to the mounting bracket and reconnect the wiring  
    harnesses.  

MOUNTING THE EQUALIZER WITH AN AMPLIFIER  

Use the illustration on page 13 of the owner's manual as a guide for   
installing the equalizer with one or two amplifiers.
