The sound system in your Porsche Cayman doesn't sound as good as you thought it would, does it? JL Audio comes to the rescue with this StealthMod audio upgrade system that'll make you very happy with the sound in your ride. This package allows you to replace the front door speakers, and increase the overall power, bringing excitement, impact, and a new clarity to your music. Adding the optional Stealthbox® subwoofer to this StealthMod will complete your Porsche's system upgrade and bring you the ultimate in customized sound.

JL C5-650x speakers

New full-range speakers

In order to guarantee superior sound reproduction in your Porsche Cayman, the factory front door speakers are replaced with JL Audio's Evolution™ C5-650x 6-3/4" coaxial speakers and crossover networks. This change will bring out all the intricacies in your music, as well as set up a clearly defined soundstage that will make it seem as if the band is playing directly in front of you. The package includes speaker and crossover mounting brackets that help simplify the installation. The rear factory speakers continue being driven by the factory radio.

JL HD900/5 5-channel amp

One amp takes care of the whole system

JL Audio's HD900/5 5-channel amplifier, bridged to 3-channel operation for this StealthMod, provides power for the entire system. This compact beast installs neatly into its own panel made for your Porsche, feeding your new speakers up to 150 watts RMS each, while its sub channel will deliver 500 watts RMS to the Stealthbox, when you add it. This power allows all your speakers to operate at peak efficiency and eliminates distortion, so you enjoy clean sound, even at high levels.

JL CL-SSI signal summing interface

Special module ties the new system to the factory system

The JL Audio CL-SSI signal summing module combines the high- and low-frequency outputs from the premium factory system, and presents a full-range stereo signal to the HD900/5 amplifier. The input sections of the Signal Summing Interface feature optimum level indicator LED's and trim pots for quick and accurate level matching that results in the cleanest and strongest signal possible. This little processor and the 5-channel amp mount to the included carpeted panel that JL created for the Cayman.

JL StealthBox for Porsche Cayman

Optional StealthBox subwoofer installed

Add the Stealthbox subwoofer

Your upgrade really won't be complete without adding some bass to the factory system. This JL Audio Stealthbox subwoofer perfectly matches your Cayman's acoustic space, and fits in without taking up much space. The Stealthbox contains one 13.5" 13TW5v2-2 subwoofer, and it lives up to its name, as it broadcasts powerful bass throughout your Cayman from the Porsche's cargo area.

Your own concert hall

Once the StealthMod installation is complete, you'll start thinking of your Cayman as your own personal concert hall, as you experience the excitement that only a first-rate car audio system can create.

Installation note: JL Audio has rated the difficulty of this StealthMod installation as high and recommends using a car audio professional to install this system, as this modification may void your factory radio's warranty. The package includes all the wires and hardware needed for a custom-fit, stealthy installation, along with photo-illustrated, detailed, step-by-step instructions.
