CAUTION
Always consider consulting a professional audio installer
before installing new speakers. Many manufacturers locate
speakers behind interior panels that require special tools to
remove. Be careful and take your time.
If you are using the speaker wire supplied with your new
speakers make sure that you run the speaker wires only
through safe areas. Do not let speaker wire make contact with
metal edges or hot engine components.

Carefully select a route for the audio signal
wires. If using existing speaker wires, confirm
that the wire is in good shape and not
shorted. In the case of an illuminated model,
route a positive and negative wire from a
switched +12V source. Avoid routing wires
through dangerous areas.
