INSTALLATION GUIDELINES

Ensure the audio system is turned off before making any connections to the amplifier, speakers or source unit. Failure to do so could result in permanent damage to the audio system.

When wiring the speakers ensure that the wire is protected from sharp objects and always use rubber grommets when wiring through metal panels. Ensure all terminals and connections are protected from the vehicle chassis and from each other as failure to do so could result in permanent damage to the audio system.

When connecting the source unit and speakers ensure you connect the positive and negative output wire from the source unit to the corresponding crossover terminals. This will ensure the audio system will be in phase.

1) Ensure there is adequate clearance and depth for the speaker to be mounted
2) Use the supplied template to mark out & cut the correct diameter hole
3) Drill four holes for the mounting screws
4) Insert the speaker and grille frame and affix with the screws provided

WARNING: Do not drill mounting holes with speaker in place as this could allow drill shavings to damage the voice coil and void your warranty.
