Turn that frown into a smile

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 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.

Perfect Porsche Sound

Written By Anonymous, Atlanta, Ga on Friday, February 27, 2015

When looking for an upgrade to the Porsche Cayman sound system with BOSE was daunting. The custom trim rings, woofer replacment and amplifier choices... JL Audio did the homework. They designed a perfect amp mounting plate.... This allows removal of the BOSE amplifier and proper mounting of there amp. the HD750 carries more then enough real power to push ssound above the road/engine noise. Next they designed the proper woofer trim ring adapters to replace the BOSE in the doors. Made the fit flawlessly. The woofer is well made and after researching the tweeter placement the place were they recommended was were JL Audio placed them! In the door in a coaxal setup. This gives the best imaging.The tweeters were full balanced highs without the harshness, I am currently runnung the AVIC Pioneer headend. The clarity and sound at high volumes is flawless,

Pros: The pros are that this is specifically designed to upgrade the Porsche Cayman. There was not cutting and modifing needed. The sound...The Sound...Brilliant highs with clear vocals. This stealthmod is highly recommended to anyone with the budget looking for a pre custom upgrade

Cons: There were very little cons that JL Audio could of overcome. Maybe a direct wiring harness adapter would of helped with the amp wiring. The price was not cheap and the door panels are a royal pain to remove and replace.
