Quick Answer
- The best subwoofer for F150 SuperCrew trucks is usually a box made for the truck: the Kicker 51KFDL7T102 fits under the rear seat of 2009 to 2026 SuperCrews with two 10″ L7T subs and 1,000 W RMS recommended power (Kicker, 2026).
- For 2015 to 2026 SuperCrews, the Skar Audio dual 12″ under-seat box is a lower-cost vehicle-specific option, but it needs an amplifier that is stable at 1 ohm (Skar Audio, 2026).
- If you do not want a separate amplifier, a powered sub such as the Rockford Fosgate P300-8P (300 W RMS) or the Kicker Hideaway 51HS10 (180 W RMS) connects straight to factory speaker wires.
- On 2015 to 2020 trucks without a factory sub, Crutchfield measures about 56″ wide, 6″ high and 10″ deep under the rear seat (Crutchfield, 2026). Removing the under-seat storage bin is often required.
- Bang & Olufsen trucks already have a sub in the rear wall and process the bass signal, so plan a line output converter such as the AudioControl LC2i Pro or Kicker KEYLOC.
The best subwoofer for F150 SuperCrew owners is the one that fits the space under or behind the rear seat and suits your factory system. A vehicle-specific under-seat box, like the Kicker 51KFDL7T102, gives the most bass without losing cab space. A powered under-seat sub is the simplest option if you want to skip a separate amplifier.
How We Picked These F-150 SuperCrew Subwoofers
We started with the space under and behind the rear seat in each SuperCrew generation, then compared subwoofers on model-year fit, RMS power, amplifier needs and how easily they connect to a factory radio. Every pick is sold on Amazon, and specs and fit lists come from each manufacturer. The recommendations are based on research and editorial analysis, following the CarAudioBlog editorial policy.
Where a Subwoofer Fits in an F-150 SuperCrew
In an F-150 SuperCrew, a subwoofer goes under the rear seat or against the back wall of the cab behind the seat. The under-seat space is the most common spot because it keeps the seat usable, but the available room changes by generation and by factory audio system.
| Generation | Factory sub | Aftermarket space |
|---|---|---|
| 2021 to 2026 (14th gen) | B&O and B&O Unleashed have a sub in the rear wall behind the seat | Under-seat boxes listed for 2021 and newer; behind-seat room changed with the 2024 cab redesign (Audio Intensity, 2026) |
| 2015 to 2020 (13th gen) | Sony and B&O trucks have an 8″ dual voice coil sub in the rear wall | About 56″ W x 6″ H x 10″ D under the seat on trucks without a factory sub (Crutchfield, 2026) |
| 2009 to 2014 (12th gen) | Premium audio trucks have a factory sub under the rear seat | Under-seat boxes made for this generation; 2015 and newer boxes do not fit (Skar Audio, 2026) |
Vehicle-specific boxes are shaped to the cab floor and the seat frame, so compare them by the maker’s fit list rather than by the simple rectangle above. Most under-seat boxes require removing the factory storage bin if your truck has one. JL Audio’s F-150 SuperCrew under-seat install guide lists that step and states that its box does not affect folding or reclining the seat.

1. Kicker 51KFDL7T102: Best Vehicle-Specific Subwoofer for F-150 SuperCrew
The Kicker 51KFDL7T102 is a down-firing enclosure built for the F-150 Crew Cab, loaded with two 10″ Solo-Baric L7T square subwoofers. Kicker lists it for 2009 to 2026 F-150 Crew Cab trucks and 2017 to 2026 Super Duty Crew Cab trucks, which covers three generations with one box (Kicker, 2026).
| Spec | Kicker 51KFDL7T102 |
|---|---|
| Subwoofers | Two 10″ L7T, down-firing |
| Recommended power | 1,000 W RMS |
| Impedance | 2 ohms, single terminal |
| Frequency response | 25 Hz to 100 Hz |
| Dimensions | 55-1/8″ W x 8-1/4″ H x 13-3/8″ D |
| Fit | 2009 to 2026 F-150 Crew Cab |
The box is MDF with heavy internal bracing and black carpet. Kicker notes that storage compartments, inverters or floor mats may need to be removed for installation. You will need a mono amplifier that delivers around 1,000 W RMS at 2 ohms.
Best for: SuperCrew owners who want the deepest, loudest under-seat option and plan to add a proper amplifier.
2. Skar Audio Dual 12″ SuperCrew Box: Best Dual 12″ Under-Seat Option
The Skar Audio L-VD-VS-2X12FORD box holds two 12″ VD-12 shallow-mount subwoofers in a sealed, down-firing enclosure for 2015 to 2026 F-150 SuperCrew trucks and the 2022 to 2026 F-150 Lightning. It is the only dual 12″ pick here, with a $439.99 regular price on Skar’s site.
| Spec | Skar L-VD-VS-2X12FORD |
|---|---|
| Subwoofers | Two 12″ VD-12 D4, pre-wired |
| Power | 1,600 W max (RMS not published) |
| Final impedance | 1 ohm |
| Enclosure | Sealed, single chamber, down-firing |
| Fit | 2015 to 2026 F-150 SuperCrew, 2022 to 2026 Lightning |
| Not compatible | 2009 to 2014 SuperCrew |
The 1-ohm load is the main thing to plan for. Skar recommends its RP-1200.1D amplifier, and any amplifier you choose must be rated stable at 1 ohm (Skar Audio, 2026). Skar publishes a max rating but no RMS figure, so size the amplifier using Skar’s recommendation.
Best for: 2015 and newer SuperCrew owners who want two 12s under the seat on a moderate budget.
3. Kicker 46TL7T102: Best Single 10″ Truck Box
The Kicker 46TL7T102 is a thin, loaded enclosure with one 10″ L7T square subwoofer, and Kicker describes it for use under or behind truck seats. With a 7-1/4″ bottom depth and 500 W RMS recommended power, it is a middle ground between a powered sub and the full dual-10 F-150 box.
| Spec | Kicker 46TL7T102 |
|---|---|
| Subwoofer | One 10″ Solo-Baric L7T |
| Recommended power | 500 W RMS |
| Impedance | 2 ohms |
| Dimensions | 20-1/4″ W x 12″ H, 7-1/4″ bottom depth |
| Location | Under or behind the seat |
Because it is not shaped for the F-150, measure the space first. The 12″ height suits a behind-the-seat install better than the 6″ under-seat gap on many trucks. A 500 W mono amplifier at 2 ohms is a good match.
Best for: owners who want the L7T’s output in a compact box that can move to another truck later.
4. Rockford Fosgate P3S-1X10: Best Shallow Behind-the-Seat Box
The Rockford Fosgate P3S-1X10 is a sealed, loaded enclosure with a Punch P3 shallow 10″ subwoofer. The box tapers from 5.3″ deep at the bottom to 3.3″ at the top, which suits the narrow space behind a SuperCrew’s rear seat.
| Spec | Rockford Fosgate P3S-1X10 |
|---|---|
| Subwoofer | 10″ Punch P3 shallow (P3SD2-10) |
| Power handling | 300 W RMS, 600 W max |
| Impedance | 1 ohm, as listed by Rockford |
| Dimensions | 13.5″ x 19.0″ x 5.3″ (3.3″ at the top) |
| Location | Behind the seat |
Rockford lists the enclosure at 1 ohm, so choose an amplifier rated for that load (Rockford Fosgate, 2026). Behind-seat room varies by year, and the 2024 cab redesign changed the back wall, so measure before you buy.
Best for: SuperCrew owners who want to keep the under-seat storage bin and mount a sub against the back wall.
5. Rockford Fosgate P300-8P: Best Powered Behind-the-Seat Sub
The Rockford Fosgate P300-8P is a powered, ported 8″ subwoofer with a 300 W RMS built-in amplifier and a slim design Rockford markets for truck installs. It takes high-level input and includes a level control, so it works with a factory radio.
| Spec | Rockford Fosgate P300-8P |
|---|---|
| Driver | 8″ Punch, ported enclosure |
| Built-in amplifier | 300 W RMS |
| Frequency response | 30 Hz to 200 Hz |
| Dimensions | 17.6″ x 11.4″ x 5.6″ |
| Inputs | Low-level and high-level, level control included |
At 5.6″ deep, it fits behind the seat in many SuperCrews without blocking the seat back. Its 300 W RMS amplifier is the most powerful among the powered picks here.
Best for: owners who want a one-box powered sub behind the seat with more output than a compact under-seat unit.
6. Kicker Hideaway 51HS10: Best Compact Powered 10″
The Kicker Hideaway 51HS10 is a compact powered 10″ sub that measures only 3-1/8″ tall, which lets it slide under the rear seat even when other parts of the floor are crowded. It includes a remote bass knob and accepts speaker-level input from 1 to 40 V (Kicker, 2026).
| Spec | Kicker 51HS10 |
|---|---|
| Driver | 10″ |
| Built-in amplifier | 180 W RMS |
| Frequency response | 25 Hz to 120 Hz |
| Dimensions | 9-7/8″ x 3-1/8″ x 14″ |
| Inputs | Low-level and high-level, remote included |
The 51HS10 replaces the earlier 46HS10. It will not match a dual-10 box for volume, but it adds low bass that factory door speakers cannot reproduce.
Best for: owners who want a small, hidden sub with a simple install and a bass knob up front.
7. JBL BassPro SL2: Best Slim Powered 8″
The JBL BassPro SL2 is a powered 8″ sub only 2-13/16″ tall, the lowest profile on this list. It includes a 125 W RMS amplifier, line and speaker-level inputs, and a remote, so it slides under most seats and connects to a factory radio (JBL, 2026).
| Spec | JBL BassPro SL2 |
|---|---|
| Driver | 8″ |
| Built-in amplifier | 125 W RMS |
| Frequency response | 35 Hz to 120 Hz |
| Dimensions | 13-9/16″ x 9-7/8″ x 2-13/16″ |
| Inputs | Line level and speaker level, remote included |
The BassPro SL2 is a bass filler more than a bass maker. It suits owners who want fuller low end without giving up the storage bin space.
Best for: stock-system trucks where you want subtle, clean bass and the easiest fit.
8. Pioneer TS-WX400DA: Best Compact Pioneer Option
The Pioneer TS-WX400DA is a compact powered sub with a 9″x5.5″ oval driver and a built-in 100 W RMS amplifier. It has speaker-level input and a wired remote, and its 20 Hz low-frequency rating is the deepest among the powered picks (Pioneer, 2026).
| Spec | Pioneer TS-WX400DA |
|---|---|
| Driver | 9″ x 5.5″ oval |
| Built-in amplifier | 100 W RMS, 250 W max |
| Frequency response | 20 Hz to 100 Hz |
| Dimensions | 11.75″ x 3.785″ x 7.785″ |
| Inputs | Speaker-level input, wired remote |
Its small footprint leaves room for the under-seat bin in many trucks. Output is modest, so treat it as a bass supplement for the factory system.
Best for: owners who want a compact, low-effort add-on with deep extension.
How to Add a Subwoofer to a Factory F-150 Stereo
To add a subwoofer to a factory F-150 stereo, take the signal from the speaker wires or the factory sub signal, feed it to your amplifier or powered sub, and run power from the battery. Powered subs with high-level inputs connect directly; loaded boxes need an amplifier and often a line output converter. Pair the sub with new door speakers for a balanced upgrade; see our picks for the best speakers for Ford F150 trucks.
The factory system decides the parts:
- Base audio trucks: tap the rear speaker wires into a powered sub’s high-level input, or into a line output converter for a separate amplifier.
- Bang & Olufsen trucks: the factory amplifier shapes the bass, so owners use a converter with bass restoration, such as the AudioControl LC2i Pro with AccuBASS or the Kicker KEYLOC, which accepts 1 to 40 V inputs (Kicker, 2026).
- Trucks with a factory sub: owners of 2021 and newer B&O trucks on the F150gen14 forum describe tapping the factory sub signal behind the driver-side rear seat.
The AudioControl LC2i Pro takes speaker-level input up to 40 V and has signal-sense turn-on, which helps when the factory radio has no remote wire (AudioControl, 2026). If you remove a factory B&O sub from the rear wall, cover the opening with a block-off plate to keep noise and dust out.
Better door speakers make any subwoofer blend more smoothly. Our guide to the best speakers for your Ford F-150 lists 6×9 and 6×8 options by truck year.
Mistakes to Avoid When Adding F-150 SuperCrew Bass
Most problems come from buying a box for the wrong generation, mismatching amplifier impedance, or skipping signal processing on premium systems. Checking these before you buy saves a return.
- Buying a 2015 and newer box for a 2009 to 2014 truck; Skar states its 2015 and newer SuperCrew boxes do not fit earlier trucks.
- Pairing a 1-ohm box, such as the Skar dual 12 or Rockford P3S-1X10, with an amplifier that is not 1-ohm stable.
- Skipping bass restoration on B&O trucks, which can leave the sub weak or uneven as volume changes.
- Forgetting the under-seat storage bin, which often has to come out for a vehicle-specific box.
- Using power wire that is too thin for a 1,000 W amplifier; follow the amplifier maker’s wire and fuse chart.
Frequently Asked Questions About F-150 SuperCrew Subwoofers
Where is the best place to put a subwoofer in an F-150 SuperCrew?
Under the rear seat is the most common spot because the seat still folds and the cab stays usable. Behind the seat works for slim boxes, but room there is tight and changed with the 2024 cab redesign.
Does the F-150 SuperCrew have a factory subwoofer?
Some trucks do. Sony and B&O systems on 2015 to 2020 trucks include an 8″ dual voice coil sub in the rear wall (Crutchfield, 2026), and 2021 and newer B&O systems also place a sub in the rear wall behind the seat.
Will a subwoofer box fit under the rear seat of an F-150 SuperCrew?
Yes, if it is made for your generation or is slim enough. Crutchfield measures about 56″ wide, 6″ high and 10″ deep under the seat on 2015 to 2020 trucks without a factory sub, and the storage bin usually has to come out.
Do I need an amplifier for an F-150 subwoofer?
Loaded enclosures such as the Kicker 51KFDL7T102 need a separate amplifier. Powered subs such as the Rockford Fosgate P300-8P or JBL BassPro SL2 have one built in and connect to factory speaker wires.
Can I add a subwoofer to an F-150 with Bang & Olufsen?
Yes. Most owners tap the factory sub or speaker signal into a line output converter with bass restoration, such as the AudioControl LC2i Pro or Kicker KEYLOC, then feed an amplifier and an under-seat box.
What size subwoofer is best for an F-150 SuperCrew?
Two 10″ or two 12″ subs in a vehicle-specific under-seat box give the most output. A single powered 8″ or 10″ sub is enough if you want fuller bass from the factory system without a large install.
Final Verdict on the Best Subwoofer for F150 SuperCrew
For most F-150 SuperCrew owners, the Kicker 51KFDL7T102 is the best subwoofer because it fits under the seat on 2009 to 2026 trucks and carries two L7T subs. The Skar Audio dual 12″ box is the value choice for 2015 and newer trucks with a 1-ohm amplifier. If you want to skip a separate amplifier, the Rockford Fosgate P300-8P is the strongest powered option here, and the Kicker Hideaway 51HS10 is the easiest to hide under the seat.
