2006-12 Chevrolet Impala SS (Crutchfield Research Photo)
You know this car. You've seen it on the road, you've seen it at the mall, and you've seen it in the rental lot at the airport. You may have even seen it in your rear-view mirror, blue lights a-flashing, the last time you got caught driving with, ummmm, "excessive enthusiasm." What we're trying to say is that Chevy sold a ton of these cars over the years. C
onsidering its stylish looks, roomy interior and decent road manners, we're not a bit surprised. In its basic form, it's a solid family car. In high-performance SS trim, it's impressively fast and almost totally invisible. Either way, the Impala will be an even better ride once you add a better audio system.

The 2006-12 Impala was offered with a choice of two factory stereo systems:
- The standard system, with an AM/FM/CD/MP3 receiver and six speakers
- An optional Bose system, with all of the above, plus two more speakers
The healthy amount of available in-dash space ensures that you'll have a wide range of aftermarket single-DIN (2" tall) or double-DIN (4" tall) receivers to choose from.

Replacing your factory radio
While today's Impala is much smaller than the leviathan machines that wore the nameplate back in the 1970's, it's not exactly a Geo Metro. It's still a good-sized car and there's plenty of room to work when you're installing a new radio.
Removing the Impala's factory system isn't terribly difficult, but it requires some skill and a reasonable amount of patience--especially when prying off the trim piece that surrounds the unit. The combination of the hard plastic trim and the softer plastic dash material can make the job seem easier than it actually is. Don't be fooled. And don't be too hasty. Use a clean panel tool (to prevent dash stains and scratches) and pry the trim off slowly (to avoid breaking the plastic) until the retaining clips release.
Pull out the trim panel, disconnect the wiring harness, and remove the panel. Then, remove the two Phillips screws that hold the climate control unit in place. Feel free to let that unit dangle while you undo the four Phillips screws securing the radio. Pull it out, unhook the harness, and put it aside.
It's important to note that the warning chimes and audible turn signals are built into the factory radio unit. Whether you have the standard system or the Bose system, you'll need to purchase an adapter to retain the warning chimes – even if you don't use OnStar. The adapter will keep the audible safety warnings functioning properly, while also providing a switched 12-volt power source for your new radio. Depending on the adapter, it might even integrate the steering wheel audio controls.
Crutchfield strongly recommends that you use one of these adapters when you replace the factory radio. The specific adapter that's right for your car depends on the car's model year whether or not it has a Bose system, but you'll definitely need one. We'll give you a deep discount on the adapter's price when you purchase it along with your new stereo.
The Metra GMOS-LAN-01 GM factory integration adapter (right), for example, retains the factory warning chimes, OnStar® capability, and the Bose amp, if present.
Your new system from Crutchfield also comes complete with a mounting kit to trim out the new radio and an adapter that connects the Impala's stock antenna to your new radio. You'll also get our free step-by-step installation instructions. Crutchfield includes these items free with most receivers.
Tools required: Phillips screwdriver, panel tool
Steering wheel audio controls
Some Impalas were available with steering wheel audio controls. If yours is one of them, you'll need an adapter to connect the controls to your new car stereo. Some of the adapters discussed above incorporate these controls. For others, you'll have to purchase the Axxess ASWC-1 adapter seperately. Obviously, you'll save a few dollars if you can use the adapter that includes this function.
Replacing your factory speakers
Replacing the factory stereo system in your 2006-2012 Impala is a relatively straightforward process. Replacing the speakers, however, is not. You can do the job yourself, but you'll need a fair amount of time, tools, and patience.

Front door speakers
The Impala's front door speaker area can accommodate 5-1/4", 6-1/2", or even 6-3/4" speakers, but mounting depth is limited to 2.9" and this is not a simple, "plug and play" job.

First, the door panel must be removed to access the speakers. This process starts by removing the sail panel and continues through several more steps involving hidden star screws camouflaged (rather cleverly, we must say) by plastic trim pieces. You'll need Torx T30 and T15 bits to remove the screws. Take your time and be careful not to damage the plastic trim during the removal process.
Once you've removed the factory speakers, you'll need mounting brackets to fit the new speakers to the openings (these brackets are included free with your Crutchfield speaker purchase). mount the adapter bracket, and secure the speakers. The factory speaker grilles on the door panel will fit perfectly over your new speakers.
Unfortunately, there isn't a wiring harness available for the speakers, so you’ll have to cut the factory speaker wire and splice in. Our free step-by-step installation guide contains detailed wiring instructions that will make the job easier.
Tools needed: Panel tool, small flat blade, Torx T30 and T15 star bits, 7mm ratchet and extension, wire cutters
The tweeters are located at the base of the Impala's "A" pillar. They're hard to reach and harder to replace. (Crutchfield Research Photo)
The factory tweeters are located in the windshield "A" pillars. This is an admirably slick bit of design, but the GM styling studio clearly wasn't thinking about potential aftermarket upgrades when they came up with this idea. The size and location of the tweeters (the pillar space is a mere 0.8 inches deep) makes it very hard to replace them, much less upgrade them. Tweeter depth is the real issue here, so your shopping choices are somewhat limited.
The wiring harness is located deep in the dash, so you'll need to cut off the factory connectors and splice the vehicle's speaker wires to your new speaker wires. You'll also need to fabricate a mounting bracket. In all honesty, this might be a job for a car stereo installation professional. To avoid all that hassle and expense, we suggest mounting aftermarket tweeters on the Impala's door panels.

Rear deck speakers

Replacing the rear deck speakers is a relatively uncomplicated process – once you get to them. The toughest part or the job is removing the rear seat (top and bottom), the interior sail panels and the deck panel in order to access the speaker location. This is a very labor-intensive process. If you're going to do it yourself, we recommend that you clear out a full afternoon and some empty garage space.Your free step-by-step installation guide contains detailed instructions.
Bose-equipped Impalas feature rear deck tweeters (Crutchfield Research Photo)
A wide variety of 6" x 9", 5-1/4", or 6-1/2" speaker sets will fit the space nicely, plus the factory brackets and grilles work perfectly and a wiring harness is available.
Top mounting height is limited to 0.8 inches, but that still leaves plenty of great speakers to choose from. A speaker adapter bracket is required for the 5-1/4" or 6-1/2" speakers, and it's included free, along with the wiring harness, with your Crutchfield speaker order.
If your car came equipped with a Bose system, you’ll also find a set of tweeters in the factory mounting bracket. There are a few 3-1/2" speakers that will fit in this space, but your options are severely limited by the rather tight 0.33 inches of mounting height.
The factory woofers receive only bass frequencies from the amplifier, so if you replace them, the aftermarket speakers will only reproduce bass.
Tools required: Panel tool, 7mm socket, 1/4" ratchet and extension. If your car has a fixed rear seat, you'll need a 10mm socket. If it has a folding rear seat, you'll need an 18mm socket.
Bass in your Impala
If you're planning to add maximum bass to your Impala, there's plenty of room for a subwoofer box in the trunk. The available area for sub-box mounting is: Width (side to side) = 36", Height = 17", Depth (front to rear) = 40" at bottom, 40" at top. There are currently no custom enclosures available for the Impala.
More options for your Impala
There are plenty of other ways to improve your Impala. Here are some of the ways Crutchfield can help.
Alpine Perfect Fit receiver kit with an Alpine receiver installed
Entertainment and navigation
If you're looking for a feature-packed unit that combines a full range of entertainment with the convenience of touch screen navigation, the Alpine Perfect Fit package will be a great addition to your Impala. This unit will retain most of your Impala's factory functions and it looks terrific. It also interfaces with your steering wheel controls, so you'll be able to pay attention to what's happening on the road ahead.
If your Impala came with a factory rear-view camera, the Metra BackupCam is all you need to connect the camera to your new car stereo. This adapter lets you keep your backup camera when you install an aftermarket stereo in select 2006-up GM vehicles. The 13" cable gives you a GMLAN29 connector on one end along with a composite video connector on the other. Once installed, you'll see images from your camera on your new receiver's screen.
Bluetooth and iPod connectivity
If you want to improve your Impala's convenience and connectivity, you can add an iPod adapter or integrated Bluetooth to the system using kits from Crutchfield. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find the kit that’s best for you.
If you're interested in adding a security system to your Impala, we recommend using the Flashlogic FLCAN databus interface because it integrates all of the alarm system function with the car's system. If you want to add remote start capability, you also need the Flashlogic FLR3 transponder ring.
