JBL continually strives to improve its products. New materials, production methods and design refinements are introduced into existing models without notice as a routine expression of our design philosophy. For this reason, Power Series Multichannel Automotive Amplifiers may differ in some respects from their published specifications and descriptions, but will always equal or exceed the original specifications unless otherwise stated.

Power Amplifier APPLICATIONS BPx MODELS
To the right are several application diagrams to help plan your subwoofer system installation. Figures 1 through 3 show how to configure the JBL Power Series subwoofer amplifiers (models BPx500.1, BPx1100.1 and BPx2200.1) for 2-channel, bridged-mono and parallel-mono operation "Setting the utput Mode" on page 6). O NOTE: For simplicity, Figures 1 through 3 do not show power, remote and input connections. NOTE: If the nominal impedance of your speaker system is close to 2 ohms, be prepared to try both bridged and parallel configurations to determine which performs better.
