The following is a brief guide to some typical problems, their probable causes, and
recommended  remedies.  Should  you  encounter  difficulties  beyond  the  scope  of  this
troubleshooting guide, consult your a/d/s/ dealer or your car stereo installer. Do not attempt
your own repairs. Any repairs to the system must be made by a/d/s/ or an authorized a/d/s/
service facility.

No sound, low or distorted sound

Check all 12-volt power connections to your radio/tape or CD player and power amplifier.
Check all power fuses related to the sound system. Check all audio connections between the
head unit and amplifier, between the amplifier and the crossover, and between the crossovers
and the speakers. If only one channel is out, try interchanging cables between channels to try
to isolate the problem. If the sound is distorted or faint, the problem may be a bad connection
or faulty ground. With the volume turned down, wiggle all wire connections to try to find an
intermittent connection. Replace any faulty wiring and reconnect loose wires. 

If none of these steps solves the problem, one or more of your car stereo components may be
defective. Have the system checked by qualified personnel.

Poor tonal balance

If the sound on the initial test is thin and weak, immediately turn down the volume and check
the woofer and tweeter connections to the crossovers to be sure they are correct. Be sure the
tweeter level control switch is properly set. 

Make sure you are getting a high-quality signal from your signal source. Check all the tone
controls, equalizer settings, tape or CD selector, and noise reduction settings. Tape players
sometimes require cleaning or adjustments to produce proper high-frequency response. If you
suspect your tape or CD player, have a car stereo installer test the unit.

Poor tonal balance may result if one or more of the drive units is not operating. While playing
a high-quality music program at a moderate level, put your ear close to each drive unit in turn
and listen for output.

Finally, if you suspect a damaged component, contact your a/d/s/ dealer or installer.
