User manual JBL JBL SG520 SERVICE MANUAL

[. . . ] If you do not feel you have the experience, do not attempt the installation yourself ­ instead, ask your authorized JBL car audio dealer about professional installation options. LOUD MUSIC AND HEARING Playing loud music in an automobile can hinder your ability to hear traffic, as well as permanently damage your hearing. [. . . ] We recommend using low volume levels when driving. JBL accepts no liability for hearing loss, bodily injury or property damage as a result of use or misuse of this product. A NOTE ABOUT SYSTEM PERFORMANCE For the best performance possible, the GTi components should be used with a two-channel amplifier with output power of at least 50W RMS per channel. The passive crossover contains impedancecompensating circuitry and has been computer-optimized for the flattest possible frequency response with the tweeter flush-mounted, on-axis with the listener. The combined responses of the speakers and passive crossover constitute a 4th-order Linkwitz-Reily acoustic alignment and cannot be duplicated with any electronic crossover currently available for car audio use. Consequently, bi-amping a GTi component system with an electronic crossover is not recommended. Flush-mounting the tweeter: first push in (1), then turn (2) Figure 10. Connecting the speakers and the amplifier to the crossover Figure 11. Adjust the crossover using the jumpers provided Figure 9.
