2006 Ford Mustang

The 2005-09 Mustang re-ignited the “pony car” wars with its combination of retro style and modern performance.  The design was an obvious homage to the classic Mustangs of the Sixties, but the styling and the stance still managed to be totally contemporary.

With the disco-era Fox platform finally retired after 25 years of loyal service, this new Mustang also sported a long-awaited new chassis that provided balanced handling no matter which V-6 or V-8 engine was under the hood.

With instantly recognizable looks and a wide variety of options and trim packages, the 2005 - 2009 Mustang offers something for almost every enthusiast. Whether you’re looking for a stylish daily driver or a bellowing muscle car, there’s a Mustang for you. And once you find your Mustang, we’re here to help you build the perfect stereo system.

Factory audio system

The factory stereo is located at the front of the car’s center console. The AM/FM/CD receiver lives in a double-bay assembly, and Ford offered three audio system options:

  • 4-speaker system: Features 6"x8" speakers in the front doors and on the rear deck, powered by a AM/FM/CD receiver.
  • Shaker 500 system: Adds two 8" dual voice coil woofers located at the mid-line of each door, powered by two amplifiers located in the driver's kick panel.
  • Shaker 1000 system: Adds two 10" dual voice coil subs in a trunk-mounted enclosure that's powered by four amps (one per voice coil) behind the enclosure.

Replacing your factory radio

The replacement process in the Mustang depends a bit on the stereo you're replacing. We'll hit the high points below, and detailed instructions can be found in your Crutchfield MasterSheet.

4-speaker system

The factory radio is fully enclosed by the console and several trim panels. Installing a new car stereo is fairly straight-forward, but it'll take a little time and effort.

You’ll need a dash kit to install a DIN (2" tall) or double-DIN (4" tall) radio. It’s possible to hard wire a new stereo to the factory wiring but getting a wiring harness will keep you from having to cut into the factory wires. You'll also need an antenna adapter that allows you to connect the Ford antenna lead to your new receiver.  The dash kit, harness, and antenna adapter needed for this installation are available at a very nice discount with your Crutchfield order, along with our free step-by-step Crutchfield MasterSheet instructions.

To begin the radio replacement process, open the center console and remove two Phillips screws at the back of the unit. Then, using the pry tool, remove the gearshift trim, followed by the console trim. Next, pry away the side trim panels located on either side of the accessory stack, followed by removal of the six 7mm screws securing the receiver/climate control trim panel. Next, remove the four 7mm screws securing the receiver to the accessory bay. Now pull out the stereo and disconnect it from the factory plug. The process takes a little time, but it's not complicated.

Installation note: The mounting kit that trims out the new radio in the Mustang dash includes a pocket that protrudes a little. As a result, you can't install a car stereo with a fold-down face in this Mustang.

Shaker 500 and Shaker 1000 systems

You'll go through the same procedure to remove the radio in the Shaker systems, with one change. Unless you plan on gutting the entire system, you'll need a special adapter in order to connect your new car stereo into the Ford amps that run the woofers in the doors (and in the trunk with the Shaker 1000 system). There are several adapters available, depending on the model year of your Mustang. You can find the right one by using our Vehicle Selector to identify your vehicle or by talking to one of our advisors. Your new receiver must have subwoofer RCA preamp outputs, because this special adapter has RCA plugs that connect to the preamp outs. This allows you to adjust  the factory subs with the sub control on your new stereo.

Special technical note:  If you experience a transient pop during turn-on/turn-off after installing a replacement receiver, it may be due to the factory remote lead employing 5 volts (instead of the normal 12 volts). You can eliminate this pop by installing a 12V-to-5V interface on the remote lead. The special adapter we recommend for this installation will also take care of this voltage conversion.

Tools needed:  Panel tool, Phillips head screwdriver, 7mm socket wrench and extension

Steering wheel audio controls

It's relatively easy to retain your Mustang's steering wheel audio controls 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 speaker system

Installing a new set of speakers in your Mustang isn't terribly difficult, but it takes some work in both the coupe and convertible models. Block out plenty of time to get the job done, and work patiently. This is an excellent DIY project that will product outstanding results.

4-speaker system (all models)
Front doors

You can install aftermarket 6"x8" speakers in the front doors, and you also have the option of putting 5-1/4" speakers in there with the help of mounting brackets. Your choices are restricted slightly by the factory grilles. Our vehicle selector will filter out the speakers that don't fit, so you can see your available options. Wiring harnesses are available to connect the new speakers to your factory wiring. Harnesses and mounting brackets are available at a special discount with every speaker order at Crutchfield.

Again, the process of replacing your speakers is straightforward, but somewhat time consuming. You'll have to remove the front-window sail panel, then disconnect the electric door controls. Next, remove the center door-latch trim, pry away the internal arm-rest screw panel, and remove the two T30 Torx screws. Pry up the power option panel, and remove all of the 7mm Phillips screws at the bottom and side of the door panel.

Finally, go back to the options panel, unclip the door latch cable, disconnect the options panel, and lift the door panel away from the entire assembly. Once the factory speaker is accessible, remove all of the T20 Torx screws that secure the speaker, and disconnect the internal wiring harness.

Rear deck (2005-2006 models)

6"x8" speakers will drop right into the rear deck openings, and wiring harnesses are available for this location. You also have the option of installing 5-1/4" speakers in mounting brackets. There's plenty of room back here, so just about any speakers will fit. To replace the factory speakers, begin by prying the grilles up from the rear deck. Once you have the screens off, remove all of the Torx screws that secure the speakers, and lift each unit from its respective bracket. Disconnect the speakers from the internal wire harness, and discard the factory units.

Rear deck (2007-2009 models)

In these later models, the rear speakers require a little more work to remove. The grilles are integrated into the rear deck, so you have to remove the deck material to get to the speakers. This involves removing the trim panels beside and above the back seat. Once again, it's not that hard, especially with our instructions, but it will take some time.

Rear side panels: (convertible)

If you have a droptop 'Stang, the speaker replacement process is a bit different. You'll start by prying uyp and removing the top part of the side panel, then you'll pry the panel out until you release the retaining clips. You won't remove it all together, though. Hold it out far enough to remove the four Torx T20 screws that secure the speaker, then pull it out, disconnect  it, and remove it. Connect it to the vehicle wires, test it out, and put everything back together.

Shaker 500 system and Shaker 1000 system 

If you have one of the factory hot rod stereos, your options for replacing speakers are exactly the same as with the non-Shaker system. Harnesses are available for both locations, as well as brackets for 5-1/4" speakers if that's your preference.

Tools needed:  Phillips screwdriver; small flat blade screwdriver; panel tool; socket driver with 7mm, 8mm, and 14mm sockets; T20 and T30 Torx drivers; drill and 1/8" bit

Bass in your Mustang

Ford Mustang Trunk

Shaker 1000 subs in the trunk (Crutchfield Research Photo)

If you have a Shaker system, you can replace the factory woofers in the doors, or in the Shaker 1000 system's trunk enclosure. But there are a few things you'll want to be clear on before you start your project.

First off, the factory amps for the door subwoofers are designed to drive low-impedance subs, so you'll get reduced output if you replace the factory subs but not the amps

You'll also have to drill new screw holes for any sub, as well as enlarge the factory cutout for some large frame subs. You'll also want to use Dynamat on the doors to prevent rattling.

You can get a lot of bass into a Mustang if you design your system properly. Our car audio experts are available by phone or chat if you need help.

To make a long story (not to mention a long installation) short, you might want to check out some of the subwoofer enclosures made specifically for the 2005-09 Mustang. You'll get great performance, plus you get to avoid the headache of trying to guess which subs are going to work in the factory enclosures.

MTX Thunderform for the Mustang

One solution is an amplified MTX ThunderForm containing a 12" sub and a 200-watt amp. It installs in the passenger side of the trunk. Having the amplifier built into the enclosure simplifies installation and your shopping.

There's also the Kicker VSS™ SubStage™ SMUS05, which comes equipped with a 10" square sub powered by a perfectly matched 200-watt amp, all housed in a custom enclosure that's optimized for sound quality.This one also fits neatly in the passenger's side of the trunk.

Other options

As you might expect with a vehicle like the Mustang, there are plenty of ways to upgrade your car inside and out. Here are a few ways we can help make your ponycar perform even better.

Security systems 

Installing a security system in your Mustang isn't easy (security systems rarely are), but it's definitely a good idea. 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.

iPod® adapters 

If you're keeping your Ford radio, you'll have some options for connecting an iPod. You'll have to remove your radio to install any of these adapters because they connect to the back of the radio. If you don't have the factory satellite radio option in your Mustang, then you can use this USA Spec adapter to connect an iPod to your radio. On theother hand, if your Mustang does have factory satellite radio, you can use this iPod adapter and keep the satellite radio tuner.

Auxiliary input

If you have another device you'd like to connect to your Ford radio, you can use this auxiliary input adapter. If you have the factory satellite radio tuner, it won't work once this adapter's hooked up.

Good, better, best   

Good:  Ford speakers are relatively high quality, so replacing your car stereo first might be the best course of action. Almost any car stereo will fit in that opening, but there's no denying that a big touchscreen receiver looks great in the Mustang's dash.

Better:  Next, you should replace the Ford speakers. If you're keeping your Ford radio, you'll want to pick some efficient speakers with superior tweeters. The speakers sit pretty high up in the Mustang's door, so you'll get really good high-end details from a nice set of speakers.

Best:  If you're into big bass, add a sub enclosure made for the Mustang with some serious power, then add an amplifier to power all the door speakers.

    I have a 05 mustang with a 500 watt amp it sound good with disc but wen i put on the radio it sound like junk i put new speaker in the car that i order from you thay are good speaker.shough i up my amp ore what do think?

    Donald, it's unlikely that the speakers are the source of your problem. If the radio sounded fine before the new speakers, then what you're likely hearing are details that were already there, but you just couldn't hear them over the factory speakers. The more-sensitive new speakers are "shining a light" on those noises. Without more specific information, it's hard to say what the problem is. If either your amp or stereo are aftermarket and the radio sounded fine before you installed them, then the problem is likely to be some form of interference noise. Check out our Noise Suppression Guide for some tips about tracking it down and eliminating it. And if you purchased either the stereo or amplifier from Crutchfield, then give our Tech Support team a call.

    So which subwoofer is going to be the higher quality product and higher quality bass?

  • Jon Paulette from Crutchfield

    Posted on 6/16/2015 3:05:28 PM

    Any of the Mustang-compatible subs mentioned this article should produce all the low-end thump most people could ever want. Then again, you might not be "most people." Quality and sound are very subjective topics, so bass performance that sounds perfectly fine to someone who likes classical music might sound pretty wimpy to someone who's into hip-hop or metal.
    Check out some Mustang and car audio forums to see what people are saying about the subs you're considering, check out the spec sheets, and, of course, feel free to call or chat with one of our advisors. Once we know more about what you like to hear and how you like to hear it, we can help you make the best choice for your car. Good luck!

    I have a 2008 mustang GT with the Shaker 500 system. I purchased the sub enclosure and amps from a Shaker 1000 system. Can I use them if I upgrade the head unit? Thanks

  • Cherie Bell from Dallas, TX

    My 2008 Mustang's factory battery was recently replaced and now the CD portion of the Shaker stereo system does not work. I want to at least retrieve my CDs in the system. I've consulted several car audio repair shops as well as the Ford house but to no avail. Why won't the CD system work with a new battery? I took the advice of a mechanic and temporarily took off the battery's pole and reattached to see if the CD system would work, and it still does not. The CD system acted like it was working when the factory battery gave out and continues to act like it is seeking something, trying to find something, but it does not work when I press 'CD'. It says 'initiating.' Thank you.

    Cherie, You could check around some online Mustang forums to see if this has happened to anyone else, but it seems likely that the CD player is toast. A dealer-sourced OEM replacement is going to be seriously expensive, but there are plenty of reasonably-priced aftermarket options available.

    Steve, This upgrade seems entirely doable, but since we haven't actually done one, we're somewhat reluctant to give you a definitive answer. For an OEM-OEM swap like this, the best place to start is probably a Mustang owners' forum. Good luck!

    I've got a 2005 Mustang w Shaker 500 and upgraded the head unit (to Jensen VX7020). Am using the Metra harness which includes adapter for subwoofer (2 RCA jacks and blue/white wires). Head unit only has 1 RCA SubOut jack. Do I need a Y-adapter to connect the 2-RCA metra harness to 1-RCA SubOut, or can I choose white or red and tape off the other? Thanks!

  • Jon Paulette from Crutchfield

    Posted on 9/16/2015 10:52:04 AM

    John, With the Shaker 500, it's okay to use the Metra harness' white RCA jack and leave the red RCA disconnected. For the Shaker 1000 system, though, we do suggest using both RCA jacks.

  • John from Staten Island

    Posted on 9/16/2015 2:27:36 PM

    Jon, Thanks for the quick reply re: 2005 Mustang/Jensen VX7020/metra woofer hookup! I've opened the dash and have been connecting/disconnecting the white RCA jack to HU sub-out RCA, yet I am not hearing an appreciable difference in bass response from the door subwoofers. Is that expected? BTW, I've wired in the axxess afdi step-down to eliminate the pop. How can I determine if the amps are getting power/sound? Thanks for your help.

  • Jon Paulette from Crutchfield

    Hi, I have a base model 2008 mustang (non-shaker). Is it possible to put in 8" woofers in my doors like the 500 and 1000 systems?

  • Jon Paulette from Crutchfield

    Posted on 11/9/2015 9:59:43 AM

    Eric, There are several high-performance component systems with 6" x 8" woofers that will fit nicely in your Mustang's doors. Anything bigger than that, and you're going to need to do some serious fabrication work.
