. . . we strongly urge you to have this unit installed by a professional auto sound installer.
Choosing The Mounting Location
We suggest that you connect the wiring and confirm that the equalizer/ booster operates properly with your system before you actually mount it in your vehicle. However, you should choose the mounting location first. Then, when the unit is connected and working properly, you can mount it without
Choose a mounting location below the dash that:
Is as near as possible to your vehicle's radio, tape player, or other main auto sound component.
Does not interfere with operation of the vehicle.
Is not directly in front of a heating vent.
Allows drilling of mounting holes, without damaging other vehicle components.
Allows enough leg room for passengers.
Allows convenient and safe routing of wires.
Then, connect the wiring as follows with the equalizer/booster as close as possible to the chosen location.
Wiring Connections
CAUTION: If the wiring harness (for power and speakers) on your older existing radio/tape player is not compatible with your new RadioShack equalizer/booster's wiring harness, we suggest that you modify the existing wiring using adapters available at your local RadioShack store. Or, you can have a qualified technician modify the older wiring for you. Modification of your new RadioShack unit will void its warranty.
Connecting Power/Speakers to the Equalizer/Booster
1.Before you make any connections, disconnect the positive (+) wire from your vehicle's battery. This reduces the possibility of damage to your system during installation.
