The Ultimate 2009-2018 Ford F-150 Extended Cab Subwoofer Enclosure Buyer’s Guide
The NVX 2009–2018 Ford F-150 custom subwoofer platform is engineered specifically for 2009 to 2018 Ford F-150 SuperCab (Extended Cab) and SuperCrew (Crew Cab) pickup trucks.
If you want a hard-hitting, physical sub-bass without cluttering your floorboards or sacrificing rear bench seat folding utility, this custom under-seat platform delivers high-output bass with zero cabin compromise.
Available in dual 10-inch and dual 12-inch sizes, you can choose between empty cabinets (VE Series) or factory pre-loaded subwoofer boxes (LVE Series) tailored to your exact power goals.
Important Cab Fitment Note (SuperCab & SuperCrew Only): All enclosures in this lineup are engineered strictly for 2009–2018 Ford F-150 SuperCab (Extended Cab featuring small rear doors) and SuperCrew (Crew Cab featuring four full doors) models. They mount flat into the floor pan recess directly underneath the rear bench seat. They will NOT fit Regular Cab models due to the absence of an under-seat floor pan.
Where Is the NVX Subwoofer Enclosure Installed in Your Ford F-150?
The NVX custom subwoofer enclosure installs directly underneath the rear passenger bench seat inside the factory floor recess.
Its contoured top profile clears the bottom cushion framework, allowing the 60/40 split-bench seat to raise or lower freely. The enclosure utilizes a down-firing sealed layout, directing the woofer cones straight down toward the carpeted steel floor pan.
This down-firing orientation provides two major operational advantages:
- Physical Cone Protection: Firing downward shields the carbon-fiber composite cones and butyl rubber surrounds from boots, cargo bags, tools, or physical impact when cargo is placed on top of folded seats.
- Acoustic Boundary Loading: Sound pressure waves reflect off the metal floor pan before expanding upward into the cab. This boundary-loading effect acts like an acoustic horn, boosting low-end efficiency and sub-bass impact inside full-size truck cabins.
Why NVX Outperforms Other Brands in Value & Engineering
Upgrading truck bass often leaves owners choosing between flimsy plastic "powered subwoofers" that distort easily or generic square boxes that slide around the rear footwell. NVX bridges this gap by delivering custom-molded, high-density wood cabinets directly to truck owners.
- Heavy-Duty 3/4" MDF Wood vs. Flexing Plastic: Cheap all-in-one powered subwoofers use thin plastic shells that flex and rattle under pressure. NVX boxes are constructed from dense, CNC-mitered 3/4-inch medium-density fiberboard (MDF) to suppress cabinet vibration and eliminate panel flex.
- 700W to 800W RMS Output vs. Weak Powered Subs: While small plastic powered boxes clip at 100W–150W RMS, these NVX dual-subwoofer setups handle an honest 700W to 800W RMS (1400W–1600W Peak), effortlessly filling large F-150 cabins with clean, distortion-free sub-bass.
- OEM Interior Integration: Covered in plush black carpet color-matched to original Ford truck interior linings, the box tucks away out of sight for a clean, factory-installed look.
Configuration Comparison: Dual 10" vs. Dual 12" & Empty vs. Loaded
Selecting the right SKU for your Ford F-150 comes down to driver sizing and hardware inclusion:
Sound Profile Breakdown
- Dual 10-Inch Configurations: Fast, articulate, and punchy. Lighter cone mass enables dual 10s to react instantly to rapid musical transients, delivering snappy kick drums for rock, country, pop, and metal.
- Dual 12-Inch Configurations: Deep, physical, and mirror-shaking. Larger cone surface area moves significantly more air volume, extending sub-bass reach for hip-hop, R&B, EDM, and low-frequency bass tracks.
Inclusion Level Options
- Empty Enclosures (VE Series): Includes the custom 3/4" MDF dual sealed box with internal lead wires and spring-loaded terminal cups. Ideal if you already own shallow-mount 10-inch or 12-inch subwoofers.
- Pre-Loaded Enclosures (LVE Series): Factory pre-loaded with NVX S-Series shallow-mount subwoofers pre-wired internally to a 1-ohm final mono load. Ready to drop under your F-150 seat and wire straight to a 1-ohm stable monoblock amplifier.
Master SKU Comparison Matrix
Every SKU on this platform is built from CNC-cut 3/4" MDF, finished in OEM-matched black carpet, and engineered for 2009–2018 Ford F-150 Extended Cab (SuperCab & SuperCrew) trucks.

Why a Sealed Enclosure Is Ideal for F-150 Truck Cab Acoustics
Pickup truck cabs are compact acoustic environments bounded by glass and sheet metal. In this cabin layout, ported (vented) enclosures can frequently create boomy, loose bass overhang that masks vocal clarity.
A sealed enclosure uses internal trapped air as a natural pneumatic spring behind the woofer cones. As the voice coils travel, internal air pressure maintains strict mechanical control over moving cone assemblies. This yields rapid transient response, precise cone recovery, and articulate kick drums that hit hard without muddying your interior soundstage.
Power Integration, Factory Radio & System Safety
Overcoming Ford SYNC Factory Bass Roll-Off
Factory Ford SYNC head units utilize built-in processing that automatically reduces low-frequency bass output as you raise the volume knob. This factory roll-off protects cheap door speakers, but starves aftermarket subwoofers of low-end signal.
Connecting an active line-output converter like the NVX XLCA2X taps into factory speaker lines, converts high-level signals into clean low-level RCA outputs, and uses integrated xBOOST signal restoration (30 Hz–60 Hz) to feed a flat, distortion-free sub-bass signal to your monoblock amplifier.
Recommended Monoblock Amplification
Because pre-loaded LVE enclosures are pre-wired to a 1-ohm final mono load and handle 700W to 800W RMS, pair them with a high-efficiency Class-D monoblock amplifier:
-
NVX VAD10001v2: Outputting up to 1000W RMS at 1 ohm, this monoblock provides clean power with ideal headroom to drive 700W–800W RMS loaded enclosures without thermal distortion or clipping. Its compact chassis easily mounts underneath a front seat frame.
100% Pure OFC 4-Gauge Power Grid
Sustaining continuous 700W to 800W RMS loads forces your amplifier to draw steady current from the battery. Installers must run a 100% pure oxygen-free copper (OFC) 4-gauge amplifier wiring kit (such as the NVX XKIT42). Copper-clad aluminum (CCA) kits create high electrical resistance, causing voltage drops and triggering protection modes on high-output Class-D amplifiers.
Frequently Asked Questions
Does this under-seat enclosure fit both SuperCab and SuperCrew F-150 models?
Yes. The under-seat floor pan geometry is identical across 2009–2018 SuperCab (Extended Cab) and SuperCrew (Crew Cab) trucks.
Can I still fold my rear seats up or down with this box installed?
Yes. The cabinet is custom-contoured to clear the bottom seat frame, allowing full 60/40 seat folding operation without contacting the box.
Will this custom box fit 2019 or newer Ford F-150 trucks?
No. 2019+ F-150 models feature updated under-seat floor bracket geometry. This platform is engineered specifically for 2009–2018 12th and 13th-Gen F-150 models.
