Skar Audio Dual 12″ Sealed Under-Seat Sub Box (Dodge Ram Fit)

This unit uses two 12″ dual-4-ohm subwoofers rated for up to 800 watts each, delivering tight bass in a sealed box that minimizes port noise. It fits under the rear seat of 2002–2018 Quad or Crew Cab Rams, making it ideal for cab space-conscious buyers who prioritize precise mid-bass and strong kick without a loud trunk rumble.
Who it’s best for: Dodge Ram owners needing a space-saving, sealed setup that emphasizes accuracy over sheer volume. Why selected: Sealed design reduces cabin resonance and improves bass control in a factory-like install. Caution: Sealed boxes can be less efficient at very high output compared to ported designs; expect tight but not cavernous bass at extreme levels.

Best for 2019–2026 Silverado and GMC Sierra Crew Cab owners who want a down-firing, sealed enclosure. This 12″ dual-driver setup uses two 12″ VD-12 D4 subs and delivers tight, controlled bass with a 800-watt per sub capability. It fits under the rear seat with minimal modifications and reduces rattles through substantial MDF construction. Choose this for a balanced, accurate low end in full-size pickups.
Who it’s best for: Chevy/GMC Crew Cab owners seeking a sealed, space-efficient bass solution with consistent performance. Why selected: Sealed design supports cleaner highs and mid-bass response. Caution: Down-firing orientation may slightly affect perceived mid-bass impact if crawl space is extremely shallow.

Best for Ford F-150 SuperCrew Cab owners who want more visceral bass using a ported design. The dual 12″ sub enclosure features a 1.6 cubic feet air space and a high-output down-firing configuration. Finished with premium trunk-liner carpeting, it fits under the rear seat with no modifications. This is the pick for listeners who want louder, deeper bass without sacrificing overall system clarity.
Who it’s best for: Ford F-150 SuperCrew buyers prioritizing louder bass and easy installation. Why selected: Ported design yields higher output and extended low frequencies. Caution: Ported boxes can be more susceptible to cabinet flex at very high volumes if installation isn’t solid.
QPower QTW12 Single 12″ Sealed Box (Pair)
Best for buyers seeking a budget-friendly, two-box sealed solution for behind-seat installations. Each enclosure uses 0.88 cubic feet of air space and 0.625-inch MDF walls for reduced resonance and solid bass definition. The pair format supports balanced stereo bass in compact trucks without substantial modification.
Who it’s best for: Budget-conscious shoppers wanting a simple, symmetrical two-box setup. Why selected: Solid MDF construction and sealed design deliver clean bass without complex installation. Caution: Sealed boxes may not deliver the same deep sub-bass extension as ported designs at very high volumes.
Q Power 10-Inch Slim Sub Box (Single)
Best for trucks with tight rear-seat space wanting a compact 10″ sealed woofer enclosure. At 7.5 inches deep, it fits behind the seat without crowding cabin space. The 0.88 cubic feet internal air space maintains tight response and clean lows, making it a practical upgrade for compact trucks or crew cabs where space is at a premium.
Who it’s best for: Small to mid-size trucks needing a slim, easy-to-install sealed box. Why selected: Slim profile and solid MDF construction balance size with bass performance. Caution: Smaller internal volume means less very-low-end excursion compared to larger boxes.
Q Power Dual 10″ Heavy-Duty Truck Sub Box
Best for drivers who want a rugged dual 10″ sealed enclosure with a reinforced MDF frame. The HD210-TRUCK design uses a 1″ MDF face and a sturdy 3.4″ box frame, offering better durability in rough road conditions or demanding installation environments. It supports a compact dual-sub setup without large footprint. Choose this if you need strength and straightforward geometry.
Who it’s best for: Truck owners who value durability and a strong structural box for long-term use. Why selected: Heavy-duty construction reduces chassis flex and rattles under energetic listening. Caution: Slightly larger footprint than some 10″ sealed options; ensure trunk or under-seat space accommodates it.
Buying Guide: Subwoofer Enclosures For Trucks
What to consider when selecting a truck sub box:
- Cab style and space: Check behind-seat depth, under-seat clearance, and available height to ensure the enclosure fits without blocking seat movement or cargo access.
- Seal vs. port: Sealed boxes provide precise, tight bass with cleaner midrange; ported boxes increase bass output and low-end extension but may require more space and vibration control.
- Internal airspace: Larger airspace generally yields more low-end extension; smaller volumes improve transients and accuracy.
- Construction quality: Thick MDF panels, solid joints, and protection against vibration improve durability and bass control.
- Subwoofer compatibility: Confirm driver size, impedance (ohms), and max power handling to match your existing amp and vehicle electrical system.
- Installation considerations: Look for boxes with simple mounting patterns, terminal cups, and carpeting that resists wear in a vehicle interior.
Choosing By Vehicle Type
Full-size pickups (like Silverado/Sierra or Ford F-150) often benefit from 12″ dual-driver configurations with under-seat or behind-seat placement for a balanced cabin presence. Mid-size trucks may favor slimmer or 10″ sealed options to conserve space while maintaining solid bass. For aggressive bass goals, ported designs can deliver louder low-end but require solid mounting to prevent rattling and may take more space.
Installation Tips
- Test fit boxes prior to final mounting to confirm clearances and access to storage areas.
- Use corrosion-resistant mounting hardware and sealants to prevent moisture intrusion in trucks.
- Secure power and grounding without stressing vehicle wiring; consider an auxiliary distribution block for multiple enclosures.
FAQ
- What size sub box should I choose for a compact truck?
Opt for 10″ or 12″ sealed boxes with low depth to fit behind seats without sacrificing space. - Is a ported box better than a sealed box for trucks?
Ported boxes deliver more bass extension and output but require more space and careful tuning to avoid cabin boomy sound. - Do I need to match the subwoofer brand to the enclosure?
It helps for mounting compatibility and optimal electrical alignment, but most enclosures accommodate common 12″ or 10″ drivers with standard cutouts. - Can I install multiple boxes in a single cab?
Yes, provided there’s sufficient space and proper wiring; ensure box volumes do not create excessive enclosure load on the amplifier. - What maintenance is needed for truck sub boxes?
Regularly inspect for loose mounting, check wiring connections, and clean any dust or moisture buildup to sustain performance. - Which enclosure is best for a tight cabin with accurate bass?
A sealed dual 12″ box, like the Skar sealed options, tends to offer tighter and more controlled bass than ported designs.
