Overview

When the Ford Fusion and Mercury Milan (shown) debuted in 2006, the occasion was much more than your average, ho-hum new car introduction. These cars marked Ford's return to the hotly contested mid-size sedan market it once dominated with the extraordinarily popular Taurus/Sable twins. Considering the size of the segment and the investment involved, this intro was a very, very big deal.

Thankfully, Ford brought forth a very good car. With a nimble chassis, handsome styling and the expected array of available options, both the Fusion and the Milan were well-liked by the motoring press and well-received by the buying public. Yes, the base model was a fleet staple, but the upmarket cars were more than a match for competitors in the segment.

Save for exterior styling differences and slightly different interior trim, the Fusion and the Milan were essentially identical cars. Thus, our Vehicle Profile covers both at the same time. Whichever one you choose, you'll be getting a smart, sleek, comfortable car with plenty of potential for audio upgrades. 

Factory system

As befitting a car intended to appeal to a wide demographic, the Fusion/Milan was available with a wide variety of factory stereo systems.

The base model, which you might recall from a drive out of the airport rental lot a few years back, was an AM/FM/CD/MP3 single disc player with an MP3 audio input and four speakers. The next step up was an AM/FM/CD/MP3 6-disc player with an MP3 input, Sirius satellite radio capability and six speakers. A half-step up from that was a similar system with iPod/iPhone integration and a USB input. The top-of-the-line Audiophile system featured a 6-disc AM/FM/CD/MP3 player and eight speakers. A DVD navigation system was added in 2007 and Ford's popular SYNC system made its Fusion/Milan debut in 2008.

If you replace the factory radio, you'll lose the factory nav and/or the AUX input connection.

Replacing your factory radio

When it comes to replacing the factory stereo equipment, the Fusion/Milan is generally easy to work with. The factory receivers are easy to reach and remove, and they can be replaced with a wide variety of aftermarket models. Single-DIN (2") or double-DIN (4") receivers will fit, with the help of a dash kit that's included free with most stereo purchases.

Depending on your car's model year and stock stereo system, you will need a wiring harness, an antenna adapter, and/or a factory integration adapter. The harness and antenna adapter, if needed, are included free with your purchase.

The integration adapter is not free, but we'll take 50% off the price of the adapter if you order it along with your new receiver. If your car does not have the SYNC system, then you can choose the PAC RP4-FD11 integration adapter. Besides letting you install a new stereo, it also makes the connections for the steering wheel audio controls, so you won't need to buy an additional adapter for that (see below).

To remove the stock receiver, you'll start by prying around the edges of the receiver trim panel until it's loose enough to disconnect the harnesses and remove the panel. Remove four 7mm screws from the radio, disconnect the harnesses and antenna, then remove the radio.

Tools needed: Panel tool, socket wrench, extension, and 7mm socket.

Steering wheel controls: If your car doesn't have SYNC and you want to retain your car's steering wheel audio controls, you'll need the PAC SWI-RC interface. It works with select receivers from Alpine, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, and Sony. For cars that are equipped with SYNC, you'll need the iDatalink Maestro ADS-MSW interface instead, to retain full functionality with a variety of receivers. If you have questions, one of our Crutchfield Advisors will be happy to help you.

Replacing your factory speakers

Mercury Milan front door

Front woofers: The stock front door speakers are 4-ohm, 5"x7" models that can be replaced by a variety of same-size or 5-1/4" aftermarket speakers. You'll need to remove the door panel to access the speakers, but this is an uncomplicated process made easier by the detailed, illustrated Crutchfield MasterSheet that's included free with your purchase.

Tools needed: Small flat blade screwdriver, Torx T20, panel tool, socket wrench, extension, and 7mm socket.

Front tweeters: With the exception of the 4-speaker base models, all Fusions and Milans will have 1.5", 6-ohm tweeters in the front doors, wired in parallel with the front door woofers.

The first step towards getting to them is removing the door panel, of course. If you're thinking about improving your car's soundstaging by installing a set of component speakers (which we highly recommend), now's the time to do so. To remove the tweeter, pry off the sail panel, disconnect the harness and remove the panel. Remove the two Phillips screws securing the tweeter to the sail panel, and set the tweeter aside.

A wide variety of component system tweeters will fit here, but a wiring harness is not available. You'll have to cut off the factory connectors and splice the vehicle's speaker wires to your new speaker wires. If you're not interested in splicing and soldering, we highly recommend Posi-Products connectors. They're a lot easier to work with and the connections will last a lot longer.

Rear door speakers: Like the front door speakers, the Fusion/Milan's rear door speakers are 4-ohm, 5"x7" models that can be replaced by a variety of same-size or 5-1/4" aftermarket speakers. You'll need to remove the door panels here as well, taking care to be gentle with the plastic bits and the ten retaining clips that hold the panel in place. All the in-depth instructions can be found in your MasterSheet.

Tools needed: Panel tool, Torx T-20, socket wrench, extension, and 7mm socket.

Bass in your Fusion or Milan

Mercury Milan rear deck speakers

Rear deck subwoofers: Fusions and Milans equipped with Ford's Audiophile system get an extra dose of sound through a pair of 6x9, 2-ohm subwoofers mounted in the rear deck. These subs are top-mounted, so they're much easier to access than the rear deck speakers in many other cars.

You'll start at the front edge and pull up on the speaker grille to release the retaining clips, then pull the grille towards the front of the car until it's free. Remove the four 7mm screws that secure the speaker to the deck, then disconnect the harness and remove the speaker.

These subs are powered by a dedicated subwoofer amp located behind a panel on the right side of the trunk. To get full-range sound from your aftermarket speakers, you'll have to bypass the factory amplifier by splicing the input and output wires together.

Because there's not much room between the speaker and the grille, not many aftermarket 6x9's will fit here. Most likely, you'll be using 6-1/2" or 5-1/4" speakers in this location. In order to mount aftermarket speakers in this location, you'll need to use the adapter brackets that are included free with your Crutchfield purchase.

On the other hand, the location is perfect for a pair of 6-1/2" subwoofers. Most of these will have an impedance rating of 4 ohms, so you'll need to install a new amplifier to power them, but you'd have to do that for any other sub anyway. This is one way to drastically improve the bass without losing any space in the trunk.

Tools needed: Panel tool, 7mm right-angle driver.

Mercury Milan trunk

Aftermarket subwoofers: As you might expect from a family sedan, albeit a sleek and stylish one, the Fusion/Milan offers plenty of trunk space for luggage, groceries, or really important things, like subwoofer boxes.

If you're planning to install a large component sub enclosure in your car, the Fusion/Milan offers 43" W x 15" H x 38" D1 x 28" D2 worth of available space. There's also ample room for a dedicated subwoofer amplifier back here, of course.

If you want to improve your sound by boosting the bass, but still need to use your trunk for its intended purpose, we offer a number of powered subwoofers that will fit nicely.

A powered subwoofer (the amp is built-in) will add depth and richness to your music without taking up half your luggage space.

Other options

Security: Adding an alarm system to your Fusion or Milan is a straightforward process — for an alarm system, that is. All of the connections are made at the ignition, behind the dash, but unless you're familiar with complex installations, it's best to have your alarm installed by a professional. If you want to add remote start capability, then you'll need a transponder bypass. We suggest the FlashLogic FLCAN module because of the extensive firmware mapping FlashLogic has done with the Ford transponder system.

Amplifiers: The Fusion/Milan has plenty of room underneath the front seats for an aftermarket amplifier, so if you want to take your sound to the next level, you won't have to worry about space in most cases. Our Crutchfield Advisors can help you find the right amp for your system.

iPod® and satellite radio adapters: If you don't want to replace the factory receiver, you can still add versatility and great sound to the system. We offer several adapters that will allow you to use an iPod, MP3 player, or satellite radio with the factory system.

Dynamat: The Dynamat 10435 Xtreme Door Kit is the perfect way to seal in sound. This heavy-duty insulating material is easy to install, and it really makes a difference. One kit will take care of the front doors. If you install a big sub, you might want to line the trunk lid as well.
