This Product is not installed by the manufacturer of a vehicle on the production line, nor by the professional importer of a vehicle into an EU Member State. You cannot input the same power as "peak power" continually. ⷠWhen the volume is set too high, the sound may be distorted or abnormal. While the listening volume is set to a high level, do not load or eject a disc or cassette tape or operate the selector and power switches of the amplifier. Cleaning -- Do not use gasoline, naphtha, or any type of solvent to clean the speakers. To connect the speaker cords to the unit, terminate the wires with female spade connectors. When using the speaker as a Three-way speaker combined with a sub woofer connect nonpolar capacitors in series (with voltage resistance greater than 63V and capacitance less than 270µF) as H. With such a connection, large energy of the low frequencies is applied to the tweeters and may destroy them. When using these speakers in multi-amplifier system, be sure to set the cut-off frequency of the tweeter to 3, 500 Hz or more. If the cut-off frequency is set to less than 3, 500 Hz, the tweeter may be damaged. However, depending on the mounting location of the speaker, the overall response and sound stage will change. [. . . ] However, depending on the mounting location of the speaker, the overall response and sound stage will change. Large power input will cause the protection circuit for the tweeter to operate, which will decrease output level. [. . . ]
