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.

Before you start

If you are replacing an older or inferior woofer, the
location is chosen for you. Make sure the woofer
fits properly in the hole for the old woofer.
If you are creating your own new location, you
must be careful to verify that there is sufficient
depth to mount the woofer.
