Breaking Down the 2017 Ford Fusion Speaker Size for Every Location
The 2017 Ford Fusion features a versatile layout that accommodates several different speaker types depending on whether you have the base six-speaker system or the premium Sony twelve-speaker setup. Identifying your specific system is crucial before purchasing hardware.
For the vast majority of owners, the primary 2017 ford fusion speaker size for both the front and rear doors is a 6.5-inch or 6.75-inch woofer. These are the workhorses of your system, handling the mid-bass and vocal frequencies that define your soundstage.
While the physical diameter is standard, the mounting depth and the bolt pattern often require specific adapter brackets. Using aftermarket brackets allows you to fit a high-quality 6.5-inch speaker into the oversized factory opening without drilling new holes into the inner door skin.
The Front Door Woofers
The front doors house the most important drivers in the vehicle. Most 6.5-inch aftermarket speakers will fit perfectly here, provided you use a mounting adapter like the Metra 82-5605, which is designed specifically for Ford vehicles.
When selecting speakers, pay close attention to the mounting depth. The Fusion has a decent amount of clearance, but excessively deep magnets can interfere with the window glass when it is rolled down into the door cavity.
The Rear Door Woofers
In the rear doors, you will find the same 6.5-inch configuration as the front. If you are a DIYer on a budget, you can often use the same model of speaker in all four doors to maintain a consistent tonal balance throughout the cabin.
Replacing these rear units helps fill the back of the car with sound, which is especially important if you frequently carry passengers. However, if you usually drive alone, focusing your budget on higher-quality front components is often the smarter move.
Dash Speakers and Tweeter Dimensions
Higher frequencies are handled by smaller speakers located higher up in the cabin. These components are responsible for the “image” of the sound, making it feel as though the band is performing right on top of your dashboard.
The center channel speaker, located in the middle of the dash, uses a 3.5-inch driver. This is a common size for dash speakers, but you must ensure the replacement is low-profile enough to fit under the factory plastic grille.
In the A-pillars, the Fusion utilizes 1-inch tweeters. Unlike the door woofers, these do not always have a “drop-in” replacement size, as manufacturers use various mounting styles for their dome tweeters.
The Center Channel Nuances
The 3.5-inch center speaker is primarily found in the Sony Premium system. If you are upgrading this, look for a speaker with high sensitivity, as it is often powered by a relatively small factory amplifier channel.
Replacing this speaker can significantly improve the clarity of voices and podcasts. Just be careful when prying up the dash panel, as the plastic clips can be brittle in extreme temperatures.
A-Pillar Tweeter Mounting
Most 1-inch aftermarket tweeters will fit in the A-pillar location with a little bit of ingenuity. You may need to use a backstrap or even a small amount of hot glue to secure the new tweeter into the factory housing.
If you are buying a component speaker set, the included tweeters will usually come with various mounting cups. Choosing the flush-mount option often yields the cleanest look if you are willing to modify the pillar trim slightly.
Navigating the Sony Premium Audio System Specifics
If your Fusion is equipped with the Sony logo on the dash, your audio architecture is more complex. This system includes additional speakers in the rear deck and a dedicated subwoofer configuration that changes your buying needs.
In the Sony-equipped models, the rear deck often houses 6×9-inch speakers that act as mid-bass drivers or subwoofers. This is a departure from the standard 2017 ford fusion speaker size found in the base trim levels.
Replacing these 6x9s can be a challenge because they are often filtered by the factory amplifier to only play low frequencies. If you install a full-range speaker here, you might find that the tweeter on the new speaker doesn’t produce any sound at all.
The Rear Deck Subwoofers
The rear deck is a prime location for adding bass without taking up trunk space. If you are replacing the factory 6x9s, look for “subwoofer” style 6x9s or high-excursion woofers that thrive in an infinite baffle (free-air) environment.
Standard coaxial speakers may not provide the low-end response you expect if the factory crossover is cutting off the high frequencies. Always check your wiring harness to ensure you are getting a full-range signal if that is what your new speakers require.
The Complexity of the Factory Amp
The Sony system uses a digital signal processor (DSP) and a multi-channel amplifier located in the trunk. This amp is tuned specifically for the factory 2017 ford fusion speaker size and impedance levels.
Most factory speakers in this system are 2-ohm drivers. If you replace them with standard 4-ohm aftermarket speakers, the volume may be significantly lower because the amplifier cannot push as much wattage into the higher resistance.
Essential Tools for a Clean Installation
You don’t need a full mechanic’s shop to change your speakers, but having the right specialized tools will prevent you from scratching your interior or breaking expensive plastic trim pieces.
A set of plastic trim removal tools is the most important investment you can make. Metal screwdrivers will gouge the soft-touch plastics of the Fusion’s door panels, leading to permanent and unsightly damage.
For the fasteners, you will typically need a 7mm socket, a 5.5mm socket, and a T20 Torx driver. Ford uses a variety of screw heads, so a multi-bit driver set is highly recommended to keep the project moving smoothly.
- 7mm Socket: Used for the main door panel bolts.
- 5.5mm Socket: Often found on smaller trim screws or dash components.
- T20 Torx: Common for securing the speakers themselves to the brackets.
- Wire Strippers/Crimpers: Essential if you aren’t using plug-and-play harnesses.
- Soldering Iron: For the most secure and permanent electrical connections.
We also suggest keeping a small magnet tray nearby. It is incredibly easy to lose the small black screws in the dark carpet of a car interior, and a magnetic tray keeps everything organized.
Step-by-Step Guide to Accessing Your Speakers
Accessing the speakers in a 2017 Fusion requires removing the interior door panels. This can be intimidating, but if you follow the correct sequence, the panels will pop off with minimal effort.
Start by removing the small plastic cover behind the interior door handle. There is usually a single 7mm bolt hidden behind this cover. Next, look in the door pull pocket for another hidden screw under a rubber mat.
Once the screws are out, use your trim tool to pry the bottom of the panel away from the metal door skin. Work your way around the edges until the plastic clips release, then lift the panel up and away from the window track.
- Disconnect the window switch wiring harness and the door latch cable.
- Unscrew the factory speaker (usually three or four screws).
- Pull the speaker out and disconnect the factory wiring clip.
- Attach your new speaker to the adapter bracket using the provided hardware.
- Connect the wiring adapter and test the sound before reassembling the door.
Always test the speaker before you put the door panel back on. There is nothing more frustrating than finishing the 2017 ford fusion speaker size upgrade only to realize a wire came loose during assembly.
Pro Tips for Improving Sound Quality Beyond Speaker Size
Simply swapping the speakers is a great start, but there are a few “pro” tricks that can make a $100 set of speakers sound like a $500 set. These involve controlling the environment inside the door.
Installing sound dampening material (like Dynamat or Noico) on the inner metal skin of the door reduces vibrations and road noise. This allows the speaker to perform more efficiently and provides a much tighter bass response.
Another secret is using foam “Fast Rings.” These foam gaskets sit around the face of the speaker and seal it against the back of the door panel. This ensures all the acoustic energy is pushed into the cabin rather than being lost inside the door cavity.
Finally, pay attention to phase and polarity. If you wire one speaker backward (swapping positive and negative), it will play “out of phase” with the others. This causes “bass cancellation,” where the speakers actually fight each other and destroy your low-end sound.
Common Mistakes to Avoid During Your Audio Upgrade
One of the most frequent errors is ignoring the impedance of the new speakers. As mentioned earlier, if your Ford Fusion has the premium amp, it expects a specific ohm load. Mixing and matching can lead to overheating the amp or poor volume output.
Another mistake is cutting the factory wiring harnesses. Instead of hacking into the car’s wires, buy harness adapters (like the Metra 72-5602). These plug directly into the factory clip and provide two spade terminals for your new speaker, making the process reversible.
Don’t forget about the Active Noise Cancellation (ANC) system. Some 2017 Fusions use microphones in the headliner to detect engine drone and play a counter-signal through the speakers. If you add a powerful subwoofer, this system can cause a loud, low-frequency hum. You may need to disable the ANC microphones to fix this.
Frequently Asked Questions About 2017 Ford Fusion Speaker Size
What is the most common 2017 ford fusion speaker size for the doors?
The most common size for both front and rear doors is 6.5 inches. While 6.75-inch speakers can also fit, 6.5-inch models are the industry standard and offer the widest variety of aftermarket options.
Do I need special brackets to install new speakers?
Yes, Ford uses a non-standard mounting pattern. You will need mounting brackets specifically designed for the Fusion to secure your new 6.5-inch speakers to the factory holes in the door.
Can I replace the speakers myself if I have no experience?
Absolutely. The 2017 Ford Fusion is a very DIY-friendly vehicle. With a basic socket set and a set of plastic pry tools, most owners can replace all four door speakers in a single afternoon.
Will upgrading speakers void my car’s warranty?
Generally, no. Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty just because you installed aftermarket parts. However, if your installation causes a direct electrical short that damages the car, that specific repair won’t be covered.
What should I do if my new speakers sound “thin” or have no bass?
Check the polarity of your wiring. If the positive and negative wires are swapped on one speaker, it will cancel out the bass from the other speakers. Also, consider adding sound deadening to the doors to improve mid-bass response.
Final Thoughts on Your Audio Upgrade
Upgrading your 2017 ford fusion speaker size components is one of the most rewarding DIY projects you can undertake. It doesn’t just make your music louder; it makes every drive more enjoyable by revealing details in your favorite tracks that you never knew existed.
Remember to take your time, use the proper trim tools to protect your interior, and always double-check your wiring before snapping the panels back into place. If you ever feel overwhelmed, don’t hesitate to consult a professional car audio installer for the more complex parts of the job, such as bypasses or amp integration.
Stay safe, enjoy the process, and get ready to hear your Ford Fusion in a whole new way!
