Factory Radio Improvement & Add-ons Information

Factory Radio Upgrades through OEM Integration and Improvement:

Here at Sonic Electronix we pride ourselves on offering a wide variety of OEM factory stereo integration options. We have a vast selection of adapters, accessories and other key components to improve your factory system.

Imagine the convenience of using iPods, iPhones, USBs, and SD Cards for MP3 playback. We have the accessories you need to add auxiliary inputs and audio/video outputs, which will allow you to connect portable media players, TV monitors, amplifiers, and subwoofers. These adapters allow you to play the music on your portable media player through your car receiver. They even allow you to use your car stereo faceplate controls to control playback of the music on your portable media player. All you need is a brand-specific adapter cord, and you can simply plug your portable music player into the stereo. For example, check out our Zune adapters, which provide direct audio to your factory receiver from a Microsoft Zune media player. Some of the adapters also enable you to view Zune video on your car monitors.

You can use your aux input for a number of cool enhancements. For example, if you want to have multiple CDs ready for playback at all times, use your aux input to connect a CD changer. Or if you want a clear AM/FM signal, even when traveling in the most obscure locations, use your factory radio's aux input (or an FM modulator) to acquire HD radio signals.

If you want to upgrade your sound without altering the theme of your vehicle's interior design, we carry vehicle specific subwoofer enclosures. We have empty sub boxes, enclosures loaded with subwoofers, and others that include built-in amplifiers. This way you can have great sound without sacrificing your vehicle's aesthetics.

Many factory stereos use preset equalization curves based on your vehicle's original OEM factory speakers. If you upgrade your factory amplifiers and speakers, you should strongly consider purchasing one of our factory sound processors that have adjustable equalization curves for optimal performance.

Now you can upgrade your factory stereo without losing those ever-so convenient steering wheel controls. We offer steering wheel interfaces that enable you to continue using your vehicle's steering wheel controls even after installing a new after-market car stereo.

For any questions, give us a call at 1-877-289-7664. Our staff will help you maximize the potential of your factory stereo.
