INSTALLATION THANK YOU for purchasing a JBL CS Series amplifier. In order that we may better serve you should you require warranty service for your new amplifier, please retain your original purchase receipt and register your new JBL amplifier online at www.jbl.com. WARNING Playing loud music in an automobile can hinder your ability to hear traffic and permanently damage your hearing. We recommend listening at low or moderate levels while driving your car.
INSTALLATION POWER CONNECTIONS The CS amplifiers require a reliable connection to the vehicle’s electrical system in order to perform optimally. See Figures 1, 2 and 3 for terminal connection locations. Please adhere to the following instructions carefully: Ground Connection Connect the amplifier’s Ground (GND) terminal to a solid point on the vehicle’s metal chassis, as close to the amplifier as possible. Refer to the wire gauge chart to determine minimum wire gauge size.
APPLICATIONS – CS300.1 The CS subwoofer amplifier is a single-channel amplifier. There are two sets of terminals to make it easy to connect multiple woofers. Either set of (+/–) terminals may be used when connecting woofers. Figure 4. CS subwoofer amplifier with two woofers connected. To the right are two application diagrams to help plan your subwoofer system installation. Figures 4 and 5 show how to configure the CS300.1 subwoofer amplifier.
APPLICATIONS – CS60.4 The CS60.4 can be set up for stereo 4-channel, 3-channel or bridged 2-channel operation, as shown in Figures 6 through 8. Front Left Front Right Figure 6.
