Why Choose JL Audio SB-F-SUPRCC/13TW5v2/DG Stealthbox System?
Don't Let Convention Get in the Way of Creating Outstanding Sub-bass
Ford's big trucks were designed to haul people and serious payloads with ease. They also present a tough challenge for a conventional subwoofer solution due to a severe shortage of unused space in the cab. It's a good thing JL Audio doesn't let convention get in the way of creating outstanding sub-bass.
They now offer two clever Stealthbox® solutions for Ford's biggest hauler: one that installs inside the center console and this one: a super-thin, all fiberglass enclosure loaded with JL Audio's revolutionary 13TW5v2 subwoofer and designed to install under the rear bench seat. So, if your console space is non-negotiable, you can still get world-class sub-bass that remains invisible and doesn't compromise your truck's people space.
Contains one 13TW5v2-2 Subwoofer In a Sealed Enclosure
Whether your miles pile up towing a boat or using your truck for work, you can now enjoy every one of them with one of their Stealthbox® solutions. The Hard Data: Contains one 13TW5v2-2 subwoofer in a sealed enclosure. 600 watt power handling. Wired for 2 ohm mono. Installs under driver side of rear bench seat. Does not affect folding or reclining of seat.
Frequently Asked Questions (FAQ)
- • What is the difference between this \"DG\" version and the \"BK\" version of this Stealthbox?
The \"DG\" suffix specifies that the premium enclosure is wrapped in factory-matched Ebony (Dark Gray) carpet to blend seamlessly with 2010–2016 Ford interiors. The \"BK\" model uses a pure Black leather/vinyl wrap.
- • Will this under-seat enclosure fit into a Ford Super Duty SuperCab (Extended Cab) truck?
No. This fiberglass shell is custom-contoured explicitly to fit under the larger rear seat floor pan dimensions of F-250 / F-350 Crew Cab models and will not clear an extended cab layout.
- • What factory truck components must be permanently removed to install this box?
You must completely unbolt and remove the factory under-seat plastic storage tray bins and the OEM subwoofer assembly to allow the massive 13.5-inch enclosure to rest flat on the floor pan.
- • Why does the bottom of my rear seat cushion press tightly against the top of the enclosure?
This occurs if the provided metal seat lift spacer brackets are forgotten during setup. You must install these spacers to lift the rear seat frame slightly to guarantee proper clearance over the down-firing driver.
- • What final wiring load impedance does this massive 13.5-inch driver present to an amp?
The enclosure comes loaded with a single high-excursion 13TW5v2-2 thin-line subwoofer. It is internally pre-wired to the external terminal cup to present a final 2-ohm mono load.
- • What is the ideal continuous RMS power handling required for this specialized slim driver?
The premium 13.5-inch driver handles up to 600 watts continuous RMS. For clean performance and optimal headroom, pair it with a solid monoblock amplifier pushing 500W to 600W RMS at 2 ohms.
- • Why does the sub-bass output seem heavily muted or clip quickly at higher volumes?
The factory Ford Sync head unit deploys aggressive internal equalization that strips out low frequencies as volume increases. An active integration processor or module is required to deliver a flat, unclipped signal to the amp.
