Please note: These are recommended starting points for tuning. In-vehicle measurements should be made to optimize the crossover for speaker placement and vehicle acoustics. Because of vehicle acoustics, the use of equalization will be required to achieve flat frequency response characteristics. Individual results may vary.

INTRODUCTION

The C5-650cw-Single is a component woofer capable of operating in a 3-way system, with a midrange and tweeter, or with only a tweeter in a 2-way configuration.
Passive crossover networks are not included with C5-Single drivers, as they are designed for active systems. Actively configured systems allow all filtering and/or equalization to be configured prior to reaching the amplifier, thus avoiding the technical compromises of passive crossover networks.
For optimum performance, we strongly recommend the use of a high-quality DSP and a dedicated amplifier channel. Precise setup of equalization, delay and crossover filters will ensure optimal in-vehicle performance.
Should you have any questions regarding the instructions in this manual, please contact your authorized JL Audio dealer for assistance, or contact the JL Audio Technical Support Department.

FACTORY LOCATION INSTALLATION

CUSTOM LOCATION INSTALLATION

Hand-tighten the screws evenly in a criss-cross pattern to avoid bending the speaker frame or stripping the mounting clips.
