What if there is no sound?
Your stereo may have a blown fuse. Replace fuse with the same amperage and style. You may have
improper wiring. Refer to the wiring guide that came with your stereo/amplifier. Check all wires for a
secure connection.
What if the sound volume is low?
Your stereo may not have enough power. You may need to install an amplifier to drive the speakers.
Why do I have a whining noise coming from the speakers?
You may have poor filtering of your alternator. If that is the case then you may need to add an alternator
filter to the power lead.
Why do I have odd sounding noises coming from the speakers?
You may have corroded battery terminals and/or a weak battery. If the terminals on the battery are
corroded, clean them, then check the sound. If the sound system is still making noises check battery
strength. If it is low, recharge or replace the battery.
Why does the speaker have sound coming from one channel only?
First make sure the balance control is set correctly. If the balance is set correctly your stereo may be
defective or the speaker may be defective. To troubleshoot this problem you MUST change both
positive and negative leads of each channel with the positive and negative leads of the opposite channel.
If the same speaker has no sound, then the speaker is no good. If the opposite speaker has no sound, then
your stereo may be defective.
