GETTING STARTED

• Turn off the audio system. It is also advisable to disconnect the negative (−) terminal of your vehicle's battery whenever performing installation work.
• Before cutting, drilling or inserting any screw, check clearances on both sides of the planned mounting surface. Also check for any potential obstacles, such as window tracks and motors, wiring harnesses, etc. Check both sides of the vehicle, many vehicles are not symmetrical!
• Always wear protective eyewear.

SPEAKER PLACEMENT CONSIDERATIONS

Grilles are not included with C1 speakers, as they are designed for installation into OEM (factory) speaker locations, located behind factory grilles. Should you need grilles, you will need to purchase aftermarket grilles separately.

!! WARNING

Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. These high-performance loudspeakers can exceed this level. Please exercise restraint in their operation in order to preserve your ability to enjoy their fidelity.

INSTALLATION OVERVIEW

C1 speakers are designed for installation into OEM speaker locations, mounted behind factory panels/grilles. Depending on the equipment used or design of your audio system, you may use the factory speaker wires or run new speaker wires to each speaker location. You will also need to run new speaker wires if you elect to mount your speakers in custom locations. Select the wiring method that is appropriate for your audio system and equipment. If you are unsure about this or any steps in the installation process, please contact your JL Audio dealer for installation help

Speaker Wiring:

If you will be using the factory speaker wires, it may be necessary to change the terminations. This may be accomplished by using an adaptor plug or simply by cutting the factory connector off and using the supplied crimp connectors to terminate the speaker wires. The larger connector is for the positive terminal and the smaller connector is for the negative terminal of each C1-650x.

If you choose to run new speaker wires, protect all wiring from sharp edges by carefully routing them, securing them and using grommets and loom where appropriate. If you are running wires into a door, use existing factory wiring boots whenever possible. If you are drilling new holes, file their edges and install rubber grommets into each hole. Wires running into car doors should be covered with a protective, flexible PVC sleeve. Make sure that the wires will clear door hinges and other structures in the door.

!! WARNING

Double check the clearance for both speakers before proceeding. Many cars are different from one side to the other!

Speaker Installation in Factory Locations:

Your new speakers have been designed to install, without modifications, into most vehicles with OEM speaker locations that accept a 6.50-inch (165 mm) speaker. Many factory 6.50-inch speakers use four mounting screws, which will line up with the mounting holes on your C1-650x speakers.

Adaptor rings are included for installation into many GM, Honda and other vehicles or those equipped with oversized 6.75-inch speaker openings. Simply remove any unnecessary mounting tabs from each adaptor ring and install, as shown in Diagrams A and B (page 5).

It is absolutely vital that the speaker frame fits into the mounting hole cleanly. This must be checked prior to tightening the screws. Never force the frame into a hole that is too small, and do not attempt to tighten the speaker onto an uneven surface. This will damage your speakers.

The speaker should fit so that air does not leak around the mounting flange. Air leaks will cause a severe degradation in sound quality. Seal any air leaks with an automotive-grade sealant material.

!! WARNING

Hand-tighten the screws evenly in a criss-cross pattern to avoid bending the speaker frame or stripping the mounting screws.
