Figure 8. Use this chart to find a copper-wire gauge that will exhibit no
more than a 0.5 volt drop for a desired cable length. If aluminum or
tinned wire is used, select an even larger gauge size to compensate for
material difference. NOTE: Cable-size calculations take into account
terminal connection resistance.
SETTING GAIN
After completing the installation, follow these steps to set the amplifier's
GAIN control:
1. Turn GAIN and BASS extender controls full left to minimum positions.
2. Turn the vehicle's ignition switch to the ON position. Then turn on the
source unit Set all tone or equalization controls to "flat" positions and
turn loudness off.
3. Play a CD or tape and set the volume control at 75% of full level.
4. Verify that the POWER indicator on the amplifier comes on.
NOTE: When using an equalizer, set its frequency controls
to"flat."
5. If appropriate, set the fader control (on the source unit) to feed the
amplifier at full level. Slowly increase the GAIN. Stop when you hear a
slight distortion of audio.
