Installation Guidelines
Ensure the audio system is turned off before making any connections to the amplifier, subwoofer or source unit.
Failure to do so could result in permanent damage to the audio system.
When wiring the subwoofer 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 amplifier and subwoofer ensure you connect the positive and negative output wire from the
amplifier to the corresponding subwoofer terminals.
1) Ensure there is adequate clearance and depth for the subwoofer to be mounted
2) Use the supplied ruler to mark out and cut the correct diameter hole
3) Drill the holes for the mounting screws
4) Insert the subwoofer and affix with the appropriate screws (not included)
