Replacing your speakers is a straightforward DIY project that requires only basic hand tools and a bit of patience. Let’s dive into the technical details and get your truck sounding the way it should have from the factory.

Understanding the 2014 ford f150 rear door speaker size and Fitment

The 2014 ford f150 rear door speaker size is officially categorized as 6″x8″. This oval-shaped speaker is designed to fit into the factory mounting bracket without any modifications to the metal door frame. While this is the standard, many enthusiasts also look at 5×7 speakers, which often share the same mounting holes.

When shopping for new units, you will find that 6×8 is a very popular size in the aftermarket world. Most major brands like Kicker, Rockford Fosgate, and JL Audio produce high-quality 6×8 speakers specifically for Ford trucks. These “drop-in” replacements are designed to match the factory bolt pattern perfectly.

One thing to keep in mind is the mounting depth available inside the door. In the 2014 F-150, you generally have about 3 inches of clearance before you hit the window track. Most standard 6×8 speakers will fit easily, but if you choose a high-performance speaker with a massive magnet, you should double-check the mounting depth specs.

SuperCrew vs. SuperCab Differences

While the 2014 ford f150 rear door speaker size remains the same across these models, the door panel removal process varies slightly. The SuperCrew has full-sized rear doors that open forward, providing plenty of room to work. The SuperCab features smaller “suicide” style doors that open toward the rear.

In the SuperCab, the speaker is located lower in the door and the panel is a bit more compact. Despite these physical differences in the truck’s body, the internal mounting bracket for the speaker is identical. You can buy the same pair of 6×8 speakers regardless of which cab style you own.

Using Adapters for 6.5 Inch Speakers

Some audiophiles prefer 6.5-inch round speakers because there is a wider variety of high-end “component” systems in that size. If you want to use a round speaker, you will need a mounting adapter plate. These plates screw into the 6×8 opening and provide a centered hole for the 6.5-inch speaker.

Using an adapter can sometimes add a bit of thickness to the mounting surface. Always ensure that the speaker’s surround or tweeter does not press against the back of the door panel’s plastic grille. If it touches, it can cause distortion or even damage the speaker over time.

Essential Tools for a Successful Installation

To tackle this project, you do not need a professional shop setup. However, having the right tools will prevent you from stripping screws or breaking plastic clips. Ford uses a mix of metric fasteners that are common in most basic toolsets.

You will definitely need a 7mm socket and a 5.5mm socket. These are the two most common sizes for the screws holding the door panel and the speaker itself. A small extension for your socket wrench will also help you reach screws tucked inside the door handle pocket.

• Panel Removal Tools: Plastic pry bars are essential to avoid scratching your paint or interior plastic.
• Wire Harness Adapters: I highly recommend picking up a pair of Metra 72-5602 adapters so you don’t have to cut your factory wires.
• Phillips Head Screwdriver: Some aftermarket speakers use standard Phillips screws for mounting.
• Electrical Tape or Heat Shrink: Useful for securing connections and preventing rattles.

If you decide to go the extra mile, consider buying some sound dampening material. Applying a few sheets of butyl-based deadener to the inner door skin can drastically reduce road noise. It also helps the 6×8 speakers produce a tighter, cleaner bass response by stopping the metal from vibrating.

Step-by-Step Guide to Removing the Rear Door Panels

Before you can address the 2014 ford f150 rear door speaker size requirements, you must safely remove the door panels. Start by rolling the windows all the way up to ensure the glass is out of the way. This also protects the window from accidental scratches while you work with tools.

Locate the small plastic trim piece behind the interior door handle. Use a small flathead screwdriver or a plastic pick to pop this cover off. Behind it, you will find a 7mm bolt that needs to be removed. Put this bolt in a safe place like a magnetic tray or the cup holder.

Next, look at the bottom of the door panel. There are usually two 6mm or 7mm bolts along the bottom edge. Once those are out, look inside the “grab handle” pocket. There is often another screw hidden under a small rubber mat at the bottom of that pocket.

1. Pop the Clips: Use your panel tool to gently pry the edges of the panel away from the door.
2. Lift, Don’t Pull: Ford door panels “hang” on the door frame. Once the clips are loose, lift the entire panel upward about two inches.
3. Disconnect Cables: Reach behind the panel to unclip the door latch cable and the power window wiring harness.

Once the panel is free, set it aside on a soft surface like a moving blanket or carpet. You will now see the factory speaker held in by four 5.5mm screws. Remove these screws, pull the speaker out, and unclip the wiring harness from the back of the driver.

Wiring and Mounting Your New Rear Speakers

Now that the old speaker is gone, it is time to install your new 6×8 units. If you bought the harness adapters I mentioned earlier, this part is a breeze. Simply plug the adapter into the truck’s factory plug and then slide the spade connectors onto the terminals of your new speaker.

Pay close attention to the polarity. The larger spade connector is usually the positive (+), and the smaller one is negative (-). If you get these switched, your speakers will be “out of phase,” which results in a significant loss of bass because the speakers are pushing and pulling against each other.

Before you screw the new speaker into the door, it is a “pro tip” to test the sound. Turn the truck’s ignition on and play some music at a low volume. Verify that sound is coming out of the new speaker and that there is no static or cutting out when you wiggle the wires.

Once confirmed, align the speaker with the factory holes. If your new speakers came with a foam gasket, apply it to the back of the speaker frame. This creates an airtight seal against the door, which is crucial for maximizing the mid-bass performance of the 6×8 driver.

Maximizing Audio Quality with Sound Deadening

Since you already have the door panels off, this is the perfect time to address the acoustics of the door. Car doors are essentially hollow metal boxes, which are terrible for sound quality. Adding a layer of sound deadening can make your $100 speakers sound like $300 speakers.

Apply the deadening material to the flat areas of the outer door skin (the metal you would see from the outside). You don’t need 100% coverage to see a benefit; even 25% coverage in the center of large metal panels will stop the “ringing” effect. This makes the door feel more solid when you close it, too.

Another great trick is to use foam speaker rings, often called “Fast Rings.” These foam circles sit around the face of the speaker and bridge the gap between the speaker and the door panel grille. This ensures all the sound energy goes into the cabin rather than getting lost inside the door cavity.

If you do a lot of off-roading, sound deadening is even more important. It helps quiet the “clatter” of gravel hitting the wheel wells and the hum of aggressive all-terrain tires. A quieter cabin allows you to hear the nuances of your music without cranking the volume to dangerous levels.

Common Pitfalls to Avoid During Audio Upgrades

One of the most common mistakes when dealing with the 2014 ford f150 rear door speaker size is over-tightening the mounting screws. The factory holes are often just thin sheet metal or plastic inserts. If you use a power drill and go too fast, you can strip the holes, leaving the speaker loose and prone to rattling.

Another issue is the window clearance. Always roll the window down slowly after installing the speaker but before putting the door panel back on. Watch from the side to make sure the window glass doesn’t strike the back of the speaker magnet or the wiring.

Check your impedance. Most factory Ford head units are designed for 4-ohm speakers. If you install 2-ohm speakers, you might cause the factory amplifier to overheat or clip. Most aftermarket 6×8 speakers are 4-ohm, but it is always worth checking the box before you buy.

Finally, don’t forget the moisture barrier. That clear plastic sheet behind the door panel is there to keep rain out of your interior. If you have to cut it to access the speaker, make sure to tape it back up securely with all-weather tape or butyl rope. A leaky door can lead to mold and electrical shorts.

Frequently Asked Questions About 2014 ford f150 rear door speaker size

What is the exact 2014 ford f150 rear door speaker size?

The exact factory size is 6×8 inches. This size is consistent across the XL, XLT, Lariat, King Ranch, and Platinum trim levels for the 2014 model year. It is also the same size used in the front doors, meaning you can buy two identical pairs if you want to replace all four speakers.

Can I fit 6.5-inch speakers in the rear doors?

Yes, you can fit 6.5-inch round speakers, but you will need an adapter plate. These plates convert the 6×8 oval opening into a 6.5-inch round opening. This is a common choice for owners who want to install high-end component sets or specific brands that do not offer 6×8 options.

Do I need to replace the factory head unit to see an improvement?

Not necessarily. While a new head unit provides more power and better EQ control, simply replacing the factory paper speakers with high-efficiency aftermarket ones will provide a noticeable boost in clarity. Look for speakers with a high sensitivity rating (90dB or higher) if you plan to keep the stock radio.

Are the rear speakers different in the Sony Premium Sound system?

The physical 2014 ford f150 rear door speaker size remains 6×8 even in the Sony system. However, the wiring might be different, and the speakers may have different impedance levels. If you have the Sony system, it is highly recommended to use a specialized wiring interface to maintain the factory amplifier’s functionality.

Is it hard to remove the rear door panels on a SuperCab?

It is slightly more technical than the SuperCrew because the handle mechanism is integrated differently. However, it still uses the same basic logic of hidden screws and plastic clips. Take your time, use a plastic trim tool, and you should be able to remove it in about 15 minutes per side.

Final Thoughts on Upgrading Your F-150 Audio
