USER MANUAL CWDRA8 JVC

Caution: Read this page carefully to ensure safe operation. WARNING WARNING

• Before mounting or wiring etc., be sure to remove the wire from the battery minus terminal. (Not doing so can cause shorts or fires.)

• When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 0.75 mm

(AWG 18) or more to prevent wire deteri- oration and damage to the wore coating.

• To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the speaker.

• In the event the unit generates smoke or abnormal smell, immediately switch the power OFF. After this, please contact your dealer or nearest service station as soon as possible. POWER OFF!

• Connect the speaker to DC 12 V, negative ground.

• Do not attempt to open or modify the unit, for this could cause fire hazard or malfunction.

• After taking the unit out of the polyethylene bag, be sure to dispose of the polyethylene bag out of the reach of children. Otherwise, they may play with the bag, which could cause hazard of suffocation. CAUTION CAUTION

• Installation and wiring of the product requires expert skill and experience. To ensure safety, be sure to have your dealer or specialist perform the installation and wiring.

• Do not install the speaker in a spot exposed to direct sunlight or excessive heat or humidity.

• Do not install the speakers in locations which may be subject to water or moisture.

• Do not install the speakers in unstable locations or loca- tions subject to dust.

• If the fuse blows, after checking to see if the wiring cord has shorted, be sure to replace with the stipulated size (amperage) fuse as displayed on the fuse box. (Using fuses other than the stipulated size can cause fires.) Check the display! To replace the fuse, refer to the vehicle instruction manual.

• To prevent a short circuit when replacing a fuse, discon- nect the wiring harness at first.

• Do not use gasoline, naphtha, or any type of solvent to clean the speaker. Clean by wiping with a soft, dry cloth.

• Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail.

• When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check that there is noth- ing hazardous on the opposite side such as a gasoline tank, brake pipe; or wiring harness, and be careful not to cause scratches or other damage.

• For ground wire mounting, do not fasten the wire to an airbag, steering or brake line system or other critical safety unit bolts or nut. (Can cause accidents.)

• When mounting, be sure to mount in a place that will not interfere with driving or be dangerous to passengers during sudden braking etc. (Cause of injury or accidents.)

• After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.

• The driver should always stop the vehicle in a safe place Information on Disposal of Old Electrical and Elec- tronic Equipment (applicable for countries that have adopted separate waste collection systems) Products with the symbol (crossed-out wheeled bin) cannot be disposed as house- hold waste. Old electrical and electronic equip- ment should be recycled at a facility capable of handling these items and their waste by prod- ucts. Contact your local authority for details in locating a recy- cle facility nearest to you. Proper recycling and waste disposal will help conserve resources whilst preventing detrimental effects on our health and the environment. before performing the following action. – Remote control operation

• Do not use the product for purposes other than on-board mounting.

• Keep the volume of sound at an optimum level. Not be- ing able to hear sounds from outside of your car can lead to traffic accidents.

Speaker cord CW-DRA8 Caution: Do not distribute the cords in the paths where they may be caught by a vehicle part or damaged. Other- wise, an electric shock or a fire due to short-circuiting may result. If there is no power con- trol terminal in the audio components, connect the blue/white wire to the ac- cessory line (ignition key switch ACC position line). If buzzing noise is heard from the speakers when the engine is running, attach a line noise filter (commercially available) to the power lead. Do not bend the vinyl-coated sec- tion of the speaker cord. Otherwise, malfunction may result. Caution:

Connect the black lead wire ground terminal directly with a screw to an unpainted metal part of the vehicle. Turning the power ON without connecting this terminal is linked to dam- age of the stereo system. Be sure to connect it. Also, painted metal panels etc., are not grounded and will not function correctly. Be careful. 1ENJ.indd41ENJ.indd4 2017/12/2818:492017/12/2818:49English

When the audio components output is a single RCA jack, use an RCA cord that converts the output into the two RCA jacks as shown above. The subwoofer output will be halved if the conversion cord is not used.

Grasp the fuse and pull up.

Insert the fuse gently into the fuse holder and push in all the way with your finger.

Close the cover. Exchange with the specified capacity fuse. Operation Fuse exchange Adjusting the sound (Remote control operation)

Turn the FREQUENCY control knob to adjust the cut-off frequency (frequencies higher than this frequency are cut off). Turn the FREQUENCY control knob to adjust the balance be- tween the bass from the rear speakers and the bass from this unit as desired.

Adjust the low frequency phase. The low frequency tone may be variable depending on the po- sition of the unit, its orientation or the turn-over frequency. This can be adjusted by changing the position of the PHASE switch. Set this switch to either position according to your liking. [0°] indicates the normal phase and [180°] means the reverse phase.

Turn the VOLUME control knob to adjust the low frequencies to the desired level. Name of each part (Remote control ) The sound is output even when the remote control unit is not connected, but the operations described in this section are not available. In this case, the volume, cut-off frequency and phase are set to the predetermined default conditions, with which the cut-off frequency is 125 Hz and the phase is 0° (positive).

Fuse Cover Fuse holder Replacement fuse 10 A Caution: Install the remote control unit in a position that does not come in the way of driving operations. Avoid installing it in a place subject to direct sunlight or direct hot wind from the heater. Otherwise, the product may be degraded and a fire hazard may result. Remove dirt from the installation position before attach- ing the hook-and-loop fastener. Caution: Be sure to replace with same capacity (amperage) as displayed on the fuse. This product is 10A. Note: Large power input will cause the protection circuit for this unit to operate, which will decrease output level. In this case, turn the volume to “MIN” for a while, then eventually this unit will automatically start working again. 1ENJ.indd71ENJ.indd7 2017/12/2818:492017/12/2818:498 English Troubleshooting Often, what appears to be a malfunction is due to user error.
