Auxiliary inputs for aftermarket stereos

An auxiliary input makes it easy to connect just about any aftermarket peripheral to your stereo, preserving the sound quality of the original source. Depending on your stereo, you'll either have a 1/8" minijack or a pair of RCA connectors on the back of the unit. Some newer models even offer this input on the front panel of the stereo, which can be great for connecting a portable player that you'll be taking in and out of the car. Some radios will require an adapter to convert the changer port into an AUX input, so check your manual or call a Sales Advisor if you have any questions.

Using an auxiliary input to connect a peripheral source will give you the best sound quality.

To connect a peripheral via an auxiliary input, install your new component (connecting it to power and ground if needed; the AUX IN only receives the audio signal). Run a cable from the audio out of the peripheral to your stereo. If your input is located on the rear of your stereo, remove it from your dash using the instructions in your vehicle's MasterSheet™. It may be convenient to connect an extension cable to the rear aux inputs, and to position the cable's female inputs at an easy-access location in your vehicle. This lets you plug in your component (you may need a minijack to RCA adapter) without removing the stereo every time. Then, set the stereo to recognize the new AUX IN connection (if necessary).

Auxiliary inputs for factory stereos

If your factory radio has changer controls, an adapter may be available to convert its changer port into an auxiliary input. Connecting an external source to your factory radio in this way gives you the best possible sound quality. Use the online Vehicle Selector or call a Sales Advisor to see if adapter is available for your vehicle.

Cassette adapters

While they're not as common as they once were, wired cassette adapters are still a convenient way to add a peripheral to a cassette-based audio system. In fact, it's a great way to connect a portable player or satellite radio tuner to a rented or leased car, since you don't need to remove the stereo or disturb the installation in any way. A cassette adapter, however, is a less than perfect solution for a permanent installation because it doesn't provide power for your source, won't sound as clear as a direct-wired connection, and clutters your dash with unsightly wires.

Cassette adapters are easy to use and to move from vehicle to vehicle.

With that in mind, connecting a cassette adapter is a relatively simple installation. The cassette unit loads into your stereo and trails a cord with a 1/8" minijack plug on the end. Just connect your source, plug it into the adapter, power it up (with either batteries or a cigarette lighter adapter), and go.

iPod adapters for aftermarket stereos

With the popularity of portable music players like the Apple iPod®, mobile audio manufacturers have sought ways to integrate them into the car without sacrificing sound quality or usability.

Apple iPod connected via an aftermarket interface to an aftermarket stereo.

iPod interface kits use a hideaway box that lets users listen to their iPod through their car speakers, control song and folder selection from the stereo's display, and charge the iPod's batteries via a single connection. The compact box connects to an input on the rear of a compatible stereo, and connects to the iPod's dock connection. The box can be secured under a front seat (or any convenient location) with included self-tapping screws or velcro strips. Some iPod adapters are nothing more than cables, and require very little in the way of mounting.

Warning: removing your seat could deactivate your vehicle's SRS system.

iPod adapters for factory stereos

If your factory radio has changer controls, an adapter may be available to convert its changer port into an iPod input. The adapter typically consists of a universal iPod connection box and a vehicle-specific adapter cable (sometimes packaged together). Connecting an iPod to your factory radio in this way gives you the best possible sound quality. Use the online Vehicle Selector or call a Sales Advisor to see if adapter is available for your vehicle.
