This enclosure holds 0.50 cu ft net per chamber. In it the Kicker CompRT 10 (48CWRT102) runs a system Qtc of 0.91–1.06 with half power at 42.6–44.2 Hz, and the cone reaches its 13.35 mm travel limit at 414 W, above the driver’s 400 W thermal rating, so heat stops you before travel does. Run a subsonic filter at 25 Hz and that becomes 434 W — +20 W, or 5 percent more power for the same 13.35 mm of travel.

01Is it a sealed driver?

Efficiency bandwidth product places the motor before anything else is decided.

EBP = Fs ÷ Qes = 48.7–56.8

D2 · EBP 56.8D4 · EBP 48.7

The CompRT 10 (48CWRT102) straddles the boundary at 48.7–56.8 depending on coil — part sealed-band, part transition. Either way it takes a sealed load happily; the coil you run shifts the alignment more than it shifts this verdict.

02What the box does to it

0.50 cu ft against a 35.4 L Vas.

α = Vas ÷ Vb = 2.50 · Fc = Fs√(α+1) = 54–56 Hz · Qtc = 0.91–1.06

D2 · Qtc 0.91, Fc 54 Hz, F3 44.2 HzD4 · Qtc 1.06, Fc 56 Hz, F3 42.6 Hz

The box lifts resonance from 28.7 Hz free-air to 54–56 Hz and half power lands at 42.6–44.2 Hz, anechoic, before any cabin gain. This system is offered in both coil variants, so both are plotted. They do not load the same box the same way.

03The watts that reach Xmax (in this enclosure)

Travel scales with the square root of power, so there is one wattage that puts the cone exactly on 13.35 mm — and a bigger one once a subsonic filter stops it wasting travel below the passband.

P_Xmax = 414–456 W unfiltered → 434–463 W with a 25 Hz subsonic

D2 · 414 W, no filterD4 · 456 W, no filterD2 · 434 W with subsonic at 25 Hz, 24 dB/octD4 · 463 W with subsonic at 25 Hz, 24 dB/octXmax 13.35 mm one-way

Every trace touches the limit and no further, because each is drawn at the exact power that puts that coil on 13.35 mm. Unfiltered that is 414 W, reached first at 34 Hz. It sits above the 400 W the driver can take thermally, so the voice coil gives up before the suspension does. The dashed traces are the same driver behind a subsonic filter at 25 Hz, 24 dB/oct: stopping the cone wasting travel below the passband lets it take 434 W before hitting the same 13.35 mm. That is 5 percent more amplifier for the price of one filter setting.

From the shop floor

Installer's take

Check your year before anything else. This fits the 2015 to 2023 F-150 and the 2017 to 2023 F-250. Ford changed the platform for 2024 and the boxes are not interchangeable, so a 2024 truck needs the other build. It is the single most common ordering mistake on this line and it costs a return shipping both ways.

Plan the amplifier location before you set the box. The enclosure fills the behind seat space by design, which is exactly where most people intend to put the amp. A compact Class D monoblock will usually go under a front seat or against the rear wall beside the enclosure, but decide that first rather than discovering it with the box already in.

Run your power and signal before final placement as well. Once the enclosure is seated behind the bench it is not a two minute job to lift it back out to fish a wire. Route, test, then set it and secure it.

How it's built

Construction

Precision Fit for Ford F-Series Trucks

Tailored Compatibility

The enclosure is designed specifically for Ford F-150 from 2015 to 2023 and Super Duty trucks from 2017-2023. Additional modifications to the truck are needed for it to fit 2024. Call for details. It provides a custom fit behind the seat, ensuring no modifications are needed and guaranteeing a seamless installation experience.

Seamless Integration

The subwoofer enclosure integrates effortlessly into your truck without interfering with any factory components. It allows for clean audio system upgrades while maintaining the truck’s factory finish.

Efficient Use of Space

This enclosure fits behind the rear seat, allowing the driver to maximize the cab's space without compromising audio performance or utility.

Optimal Sound Performance

Enhanced Bass Response

The enclosure's sealed design optimizes the bass output, delivering rich, deep sound. This design ensures that you can enjoy enhanced audio performance without sacrificing clarity.

Vibration Minimization

The structure is crafted to minimize vibrations often occurring with standard subwoofer enclosures. This ensures smooth, clean sound even at high volumes.

Sound Quality Retention

This enclosure is engineered to retain sound quality even when space is limited, offering powerful audio output that complements both factory and aftermarket audio systems.

Maintains Under-Seat Storage Access

Practical Design

The enclosure is engineered to maintain access to the under-seat storage in your truck. This makes it ideal for users who need to preserve storage options while enhancing their audio experience.

Convenient Setup

Installation does not interfere with the truck’s seat functions, allowing easy access to under-seat compartments. This design feature maximizes usability for drivers who require frequent storage access.

Versatility

The enclosure’s compatibility with various storage setups makes it a versatile option for Ford truck owners who prioritize space and sound quality.

Compatible with Multiple 10" Woofers

Flexible Subwoofer Choices

The enclosure is compatible with several 10-inch subwoofer models, giving users flexibility in their audio setup. It offers versatility for various subwoofer preferences without compromising performance.

Designed for Performance

The enclosure is built to handle high-output subwoofers, allowing users to push their audio system to its limits. This makes it a strong contender for users seeking superior bass performance.

Perfect Balance of Size and Power

Despite its compact form, the enclosure can house subwoofers that deliver substantial power. This design feature ensures a balance between space efficiency and sound output.

Before you order

Questions

Which trucks does this fit?

The 2015 to 2023 Ford F-150 and the 2017 to 2023 Ford F-250. Ford changed the platform for 2024 and the enclosures are not interchangeable, so a 2024 or later truck needs our 2024 to 2026 build instead. Check your model year before ordering. It is the most common mistake on this line.

Do I lose seat travel or storage?

No. The enclosure is cut for this specific cab rather than adapted to it, so it sits behind the rear bench without fouling the seat or the factory under seat storage. That is the whole reason a vehicle specific build exists. A universal box in the same space either does not fit or costs you something.

Do I need an amplifier, and how much power?

Yes. This is a passive enclosure with no amplification built in. Target 300 to 400 watts RMS at your final impedance. The CompRT 10 is a dual 4 ohm driver, so parallel gives 2 ohms and series gives 8. Most truck builds run 2 ohms into a compact Class D monoblock. If you are keeping the factory head unit you will also need a line output converter or a DSP with speaker level inputs.

Why only 0.50 cubic feet?

It is inside Kicker's published 0.4 to 1.25 cubic foot sealed range for the CompRT 10, and it suits a truck cab specifically. A cab is small, sealed and heavily reinforced, so cabin gain below 80 Hz is stronger there than in almost any other vehicle. A larger box chasing deeper extension usually just produces boom you have to EQ back out. Tighter gives you control and lets the cab do the low end work.

Where do I put the amplifier?

Plan this before the box goes in. The enclosure fills the behind seat space by design, which is where most people were intending to put the amp. A compact Class D monoblock will usually fit under a front seat or against the rear wall beside the enclosure. Route and test your power and signal runs before final placement, because lifting the box back out to fish a wire is not a two minute job.

Will the CompRT handle a truck cab environment?

That is what it was designed for. Both cone and surround are UV resistant, and Kicker's Forced-Air Cooling runs the motor around 20 percent cooler than their previous generation. A cab bakes in summer and freezes in winter, and heat is what kills subwoofers. This driver was built with that in mind rather than adapted to it.

What is the warranty on this system?

The enclosure carries a 2 year limited warranty on craftsmanship and materials, which is the standard across the Vehicle Specific line. The Kicker CompRT 10 carries its own manufacturer warranty separately, handled through Kicker.

Is there a higher output version for the same space?

Yes. We build a PR Edition for the same cab that uses a passive radiator to extend the low end further without needing port length the space does not allow, and a dual 10 version for the same platform if you want more cone area. We also build this cab with the JL Audio 10TW3 and the Alpine RS-W10D4 if you prefer a different driver.
