INSTALLATION
GUIDELINES
To make sure your equalizer works
properly with your autosound system,
install your equalizer in the following
order.
1. Carefully read all the installation
instructions and make a list of the
quantity and length of shielded
audio cables you will need. Your
local RadioShack store carries a
large selection.
Note: Use wire twist connectors
(such as RadioShack Cat. No. 64-
3057) to make wire-to-wire con-
nections.

2. Before you begin installing your
equalizer, disconnect the cable
from the vehicle battery's negative
(–) terminal. This disconnects
power and helps protect your
vehicle's electrical system while
you work with the vehicle's wiring.
Note: After you install the equal-
izer, you must reset your vehicle's
clock, autosound system's tuner
memories, and any other clock or
memory devices connected to
your vehicle's electrical wiring.
3. Connect the input source.
• If your autosound system has
line-out jacks, see "Using the
Autosound System's Line-Out
Jacks" on Page 6.
Note: This is the preferred con-
nection method.
• If your autosound system does
not have line-out jacks but has
only speaker output wires, see
"Using the Autosound Sys-
tem's Speaker Wires" on Page
7.
4. Connect the output amplifier by
either:
• Using your autosound system's
amplifier (see "Using Your Auto-
sound System's Amplifier" on
Page 8)
• Using separate amplifiers (see
"Using Separate Amplifiers" on
Page 9).
5. Connect power, then test the con-
nections.
6. Set the crossover frequency.
7. Mount the equalizer.
