CAR-AUDIO SUBWOOFER BOX
THANK YOU for choosing a JBL® CS Series subwoofer box. This product has been designed to deliver great bass
performance from a compact, easily installed subwoofer box. To get the best performance from your subwoofer box, it
is strongly recommended that installation be entrusted to a qualified professional. Although these instructions explain
how to install your product in a general sense, they do not show specific installation methods that may be required for
your particular vehicle. If you do not have the necessary tools or experience, do not attempt the installation yourself.
Instead, please ask your authorized JBL car audio dealer about professional installation. In order that you may be
better served, should you require warranty service, please retain your original sales receipt and serial number.
GENERAL CARE
Do not use any cleaners or solvents on the speaker cone.
INSTALLATION WARNINGS AND TIPS
WARNING: Playing loud music in an automobile can permanently damage your hearing as well as hinder your ability
to hear traffic. Listening at low levels while driving is recommended. Harman accepts no liability for hearing loss, bodily
injury or property damage resulting from use or misuse of this product.
INSTALLATION TIPS
Always wear protective eyewear when using tools.•
Turn off all audio components and other electrical devices before you start. Disconnect the (–) negative lead from •
your vehicle’s battery.
Check clearances on both sides of a planned mounting surface. Be sure that screws or wires will not puncture brake •
lines, fuel lines or wiring harnesses, and that wire routing will not interfere with the safe operation of the vehicle.
When making electrical connections, make sure they are secure and properly insulated.•
Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl, to keep material from snagging •
in a drill bit or saw.
Do not mount speakers where they will get wet.•
CHOOSING A MOUNTING LOCATION FOR THE SUBWOOFER BOX
Choose a mounting location that doesn’t interfere with cargo, the fold-down rear seat or the trunk lid. The best location
is usually a corner of the trunk or cargo area.
