JBL GT-X1250T - 12" Car Audio Bass-Reflex Subwoofer Tube Manual

INSTALLATION WARNINGS AND TIPS

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 it from snagging in a drill bit or saw.
• Do not mount speakers where they will get wet.

CHOOSING A MOUNTING LOCATION FOR THE SUBWOOFER TUBE
Choose a mounting location that doesn't interfere with cargo, the folddown rear seat or the trunk lid. The best location is usually a corner of the trunk or cargo area.

GENERAL CARE
Do not use any cleaners or solvents on the speaker cone.

CONNECTIONS

Connect the "+" and "–" terminals on the subwoofer tube to the amplifier's outputs, observing proper polarity. Use at least 0.5mm² speaker wire for the connections to the subwoofer tube.

Note: We recommend a JBL amplifier to power your GT-X1250T. Set the amplifier's crossover to LPF (Low-Pass Filter) and set the crossover frequency to a value within the range marked in gray in the drawing below (50Hz – 100Hz). For details regarding the installation of your amplifier or other amplifier settings, please consult the installation manual for your amplifier.
