Turn that frown into a smile

The sound system in your Cadillac CTS sedan 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 Cadillac's system upgrade and bring you the ultimate in customized sound.

JL Audio  EvolutionT C5 Series 6-3/4" 2-way car speakers

New full-range speakers

In order to guarantee superior sound reproduction in your CTS, the factory front door speakers are replaced with JL Audio's Evolution™ C5-650x 6-3/4" 2-way speakers. Their 2-way design brings 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 factory Cadillac tweeters get their crossovers modified, so they'll complement the new speakers and amplifier. The package includes speaker mounting brackets that help simplify the installation. The rear factory speakers continue being driven by the factory radio.

JL Audio XD500/3 3-channel amplifier

One amp takes care of the whole system

JL Audio's XD500/3 3-channel amplifier provides power for the entire system. This compact beast feeds your new components up to 75 watts RMS each, while its sub channel will deliver 300 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 Audio includes a custom amp bracket, so you can mount the amp under the rear deck in your CTS.

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 Cadillac's acoustic space, and fits in without taking up much room. The Stealthbox contains one 10" 10TW3-D4 subwoofer, and it lives up to its name, as it broadcasts powerful bass throughout your CTS.

Your own concert hall

Once the StealthMod installation is complete, you'll start thinking of your Cadillac 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.
