2007-2009 Saturn Sky

In a Nutshell

This article will explain how to install new car stereo gear in your Saturn Sky. Check it out and then use our vehicle selector to find the gear that will fit your car. 

The Sky is a fun car already, but some new stereo gear will up the enjoyment level even more. The receiver is easy to replace, as are the pillar, door, and side panel speakers.

The rear sub is a hassle to get to, and there aren't a lot of subs that fit in this rather shallow mounting location. Can you do this? If you want it bad enough, yes, but it's not something we'd recommend for the average DIY-er. A powered subwoofer in the trunk will do the job just as well.

Full Story

Overview of the Saturn Sky

By the time the Saturn Sky made its debut in 2007, Saturn was no longer a "different kind of company" making a "different kind of car." The once-unique brand had morphed into a full-fledged member of the GM family, sharing platforms and parts with other members of the General's global group of nameplates. The Sky, in fact, shares its GM Kappa platform and much, much more with the Pontiac Solstice.

Despite the fact that both brands eventually disappeared into the ether, this is not necessarily a bad thing. The Solstice, which went from car show superstar to production vehicle in near-record (especially for GM) time, was a very cool little machine. The Sky is pretty nifty in its own right, with sleek, subtle styling that's quite different from its more aggressive-looking sibling. Whether you're into blasting along mountain roads or cruising down beachfront highways, the Sky is a fun, willing sports car that's up for any adventure. A new stereo will only add to the fun.

This article is an overview of your vehicle's audio system and its upgrade options. If you're looking for step-by-step instructions on how to install a car stereo or speakers in your Saturn, there's nothing better than our exclusive Crutchfield MasterSheet™. This detailed, well-illustrated document is free with your Crutchfield order, or you can purchase one separately for $9.99.

Factory stereo system

The Sky's base stereo was an in-dash AM/FM/CD player with an aux input and six speakers. The optional Monsoon system featured a 6-disc AM/FM/CD/MP3 system and 7 speakers. Other available features included OnStar, XM satellite radio, a trip computer, and, for 2009, Bluetooth® connectivity.

Single-DIN (2" tall) or double-DIN (4"tall) aftermarket receivers will fit in the dash opening. If you replace the factory radio, you'll lose the factory XM satellite radio capability and some other features, but you can easily regain what you're losing with the right aftermarket receiver.

Removing the factory radio isn't exactly easy (Crutchfield Research Photo)

Your Sky's warning chime is built into the factory radio, so you'll need to purchase an adapter that retains that audible safety warning and also provides a switched 12-volt power source for your new radio.

Crutchfield strongly recommends that you use the recommended adapter when your replace the factory receiver. So much so, in fact, that we'll give you a very nice discount on the purchase price with most receiver purchases.

Replacing your factory radio

Whether your Sky is equipped with the base stereo or the Monsoon system, removing the factory gear involves the same basic tasks. In the case of the factory receiver, however, there are an awful lot of them.

Just getting to the receiver requires a remarkable amount of dashboard disassembly. Once you've removed the old one, installing the new receiver requires a mounting kit, which needs to be modified before you can use it. If you're an experienced hand with car audio installations, this isn't an impossible task by any means, but it is a cut or three above the standard degree of difficulty for this sort of thing. Make sure you understand the instructions that come with the kit and if you have any doubts, call our Crutchfield Tech Support team before you make any cuts.

The Crutchfield MasterSheet included free with your Crutchfield car audio purchase contains illustrated, step-by-step instructions that will guide you through the process. If you're an experienced hand at DIY car audio installations, you can probably handle the job on your own, but you might want to give our Tech Support team a call before you start. Then again, you also might want to simply trust the work to a car audio professional. 

Tools needed: Panel tool, small flat blade screwdriver, right-angle 7mm driver

Steering wheel audio controls

It's relatively easy to retain the steering wheel audio controls in your Sky when you install a new stereo. When you enter your vehicle information, our database will choose the adapter you need to make your factory steering wheel controls work with your new receiver.

Replacing your factory speakers

The stock speakers aren't awful, but aftermarket audio gear will really transform the sound in your Sky.

Front pillar tweeters

You'll find a set of roughly 1.5" tweeters located in the front pillars. They're quite easy to get to and reasonably easy to replace, so if you're thinking about installing a set of component speakers, you're in luck. 

You'll need an adapter to hold the new tweeter in place, and our universal backstrap can be bent and shaped into an easy, efficient solution.

Tools needed: Panel tool, Torx T30, small flat blade screwdriver

Door woofers

The stock speakers are 6-3/4", 2-ohm models that can be replaced by a variety of 6-1/2" or 5-1/4" or 6-3/4" aftermarket speakers. You'll need brackets for the smaller sizes, and they're included free with your Crutchfield speaker purchase.

Replacing the woofers is pretty straightforward. You'll need to remove the door panel, of course, but that's not terribly difficult. The key here is to take your time and be careful with prying away the trim pieces. You'll also be removing a fair number of screws, so have a container handy to keep them from "disappearing" before you need them again.

Be aware that if you replace the 2-ohm factory speakers with standard 4-ohm aftermarket speakers, you'll hear a noticeable drop in volume. Instead, make sure your new speakers also have a low impendance rating of either 2 or 3 ohms.

Tools needed: Panel tool, small flat blade screwdriver, needle-nose pliers, 7mm driver, Phillips screwdriver

Rear side panel speakers

The Sky's rear side panels house 3-1/2", 4-ohm speakers that are reasonably easy to get to and easy to replace with same-size aftermarket speakers.

The panel will need to come off, of course, but that's no big deal. Just remember to work carefully and wrap your panel tool in a clean cloth to prevent scratches.

You'll need a pair of pliers to remove the four self-threading nuts that hold the speaker in place. These could be quite snug, so be patient here as well. You'll need these nuts to attach the new speakers, and you don't want to strip them during the removal process.

Tools needed: Panel tool, pliers

Getting to the sub, on the other hand, involves some work (Crutchfield Research Photo)

Bass in your Saturn Sky

The Sky's rear subwoofer, an 8" model mounted behind the passenger seat on the rear "wall" of the interior, is an interesting case.

Removing the sub involves a lot of small steps, and it looks kind of daunting when viewed in list form on the Crutchfield MasterSheet. It really isn't as bad as it looks, though, since you're basically prying out trim panels and retaining clips.

Even so, it still might not be worth the time and effort involved. Due to mounting depth issues, only a few aftermarket subs fit in this opening, so your options are limited.

A wiring harness is not available, so you'll either need to splice the wires or make connections using PosiProducts connectors. You new sub will most likely need more power than the OEM sub, so you'll want to add a new amplifier. Helpfully, the factory amp is also located on the Sky's rear interior wall.

Like most two-seat sports cars, the Sky offers little in the way of free space. With a mere 20" W x 9" H x 12"/4" D to work with — and that's with the top UP — your best bet for even bigger bass is a compact powered subwoofer. A very small sub will produce thump and should fit neatly into the trunk. Just remember that with the top up, you have very little trunk space in this car. When it's down, you have almost none.

Tools needed: Panel tool, Phillips screwdriver, socket wrench, 10mm deep socket, 8mm socket, Phillips screwdriver

Other options for your Sky

There are lots of things you can do to make your Sky into an even more enjoyable ride. Here are few ideas:

Speaker baffles

A set of inexpensive foam baffles can help you get the most out of your new set of speakers. These soft, water-resistant baffles compress easily within the doors, forming a seal that reduces panel vibration and improves sound. If you cut a hole in the bottom of the baffle, or remove the entire bottom, you'll maintain good bass response while still protecting your speaker.


Like most drop-tops, the Sky lets in a good bit of road noise. If you're serious about sound, installing Dynamat in your doors will help keep noise and rattles to a minimum and allow you to enjoy your new stereo to the fullest. If you add a sub, you'll also want to line the top of the trunk.


Though we're definitely not collector car experts, our gut tells us that the Sky just might have some long-range investment potential. It's difficult to gauge the future availability of spare parts, but "new old stock" radios could be hard to find, especially for an "orphan brand" like Saturn. So, if you replace your Sky's factory radio and/or speakers, hang onto them. You can always put them back when it's time to sell the car.

If you don't want to replace the factory equipment at all, but still want to enjoy great sound while you're enjoying your car, we offer a wide variety of adapters that will allow you to use an iPod, MP3 player, or satellite radio with the Sky's factory audio system.


Installing a security system in your Sky isn't easy (security systems rarely are), but it's less complicated than it could be. Our Crutchfield Advisors can help figure out what you need to get the job done, but we usually recommend taking your car and new gear to a professional installer.
