Best Slim Subwoofer For Truck: Compare 10 Options

#1 · Best Overall

1. Rockford Fosgate R2S-1X12

• Dimensions D x W x H: 8.3"D x 31.3"W x 16"H
• Enclosure Material: Medium Density Fiberboard
• Compatible with Vehicle Type: Truck
• Speaker Size: 12 in

Best for: Single-cab wedge enclosure.

Why it ranks #1: Its wedge-shaped 12-inch loaded enclosure is designed for single-cab trucks with limited seat travel and handles 250 watts RMS at 2 ohms.

A wedge enclosure optimized for single-cab trucks with limited seat travel is the defining feature of Rockford Fosgate’s loaded R2S-1X12. The sealed box houses a shallow 12-inch subwoofer and uses its angled shape to address a common cabin-space constraint while retaining a larger driver size.

The 31.3-inch-wide wedge is 8.3 inches deep and 16 inches high, so its dimensions matter when planning placement behind or alongside a truck seat. Internally wired to a 2-ohm amplifier load, the enclosure presents a specified connection load without requiring the buyer to wire the voice coils. Its 250W RMS and 500W maximum handling ratings help with amplifier matching, while the sealed construction and carpet-covered MDF form a complete loaded enclosure.

Skip it if you need an under-seat powered package with an included amplifier; Seventour ST800 combines a 10-inch subwoofer and built-in amp.

This loaded wedge fits truck owners prioritizing a 12-inch subwoofer in a single-cab layout with restricted seat travel. Plan around its 31.3-inch width and provide a compatible amplifier for the specified 2-ohm load.

#2 · Thinnest Profile

2. Rockville SS10P

• Dimensions D x W x H: 16"D x 12"W x 5"H
• Enclosure Material: Aluminum
• Compatible with Vehicle Type: Car, Truck
• Speaker Size: 10 in

Best for: Three-inch powered under-seat fit.

Why it ranks #2: The powered 10-inch unit is listed as only 3 inches high, with high-level and RCA inputs for factory or aftermarket systems.

At just 3 inches high, Rockville’s SS10P targets under-seat installations where enclosure height is the first constraint. Its 10-inch subwoofer and built-in amplifier combine in a compact powered unit, while high-level and RCA inputs give installers routes to connect either factory or aftermarket audio systems.

The cast-aluminum enclosure is specified to stay cool under seats, supporting operation in a compact location where heat management matters. High-level inputs allow connection to a factory system without preamp outputs, while RCA inputs support compatible aftermarket setups; adjustable input sensitivity and auto turn-on add practical installation controls. The listed overall dimensions are 13.6 by 9.65 by 3 inches in the product features, so buyers can compare the low height with their available space.

Skip it if you want a 12-inch loaded wedge for a single-cab truck; Rockford Fosgate R2S-1X12 is specified for limited seat travel.

Choose the SS10P for an under-seat truck setup that needs a low-profile powered unit and factory-stereo input flexibility. Compare its 13.6-by-9.65-inch footprint with the space available beneath your seat.

#3 · Built-In Amplifier

3. Rockford Fosgate P300-10T

• Dimensions D x W x H: 7.9"D x 13.3"W x 21.7"H
• Enclosure Material: Wood
• Compatible with Vehicle Type: & SUVs, Select Cars, Truck
• Speaker Size: 10 in

Best for: Adjustable powered-box tuning.

Why it ranks #3: This truck-compatible 10-inch enclosure pairs its subwoofer with a 300-watt Class-D amplifier and adjustable crossover, bass boost, and phase.

A built-in 300-watt Class-D amplifier turns Rockford Fosgate’s P300-10T into a self-contained 10-inch bass system, avoiding a separate amplifier purchase and placement decision. Its enclosure has a slim profile, while adjustable crossover, bass boost, and phase controls let owners tailor integration with a factory or aftermarket system.

The included amplifier is impedance-matched to the 10-inch subwoofer, keeping the core powered components together in a wood enclosure. A 12dB-per-octave low-pass crossover and adjustable bass-boost EQ give the installer ways to shape the sub’s contribution to the rest of the system; the 0°/180° phase switch offers another adjustment during setup. Its 21.7-inch width and 7.9-to-4.8-inch depth profile still require space to place the box.

Skip it if you need a shallow 12-inch wedge for a single-cab truck; Rockford Fosgate R2S-1X12 is specifically optimized for limited seat travel.

Pick the P300-10T if you want an amplified 10-inch enclosure with several sound adjustments for system integration. Its listed width and depth profile make placement worth checking in a truck with tightly limited cabin space.

#4 · LED Option

4. Seventour ST800

• Dimensions D x W x H: 2.7"D x 13.5"W x 10.2"H
• Enclosure Material: Aluminum
• Compatible with Vehicle Type: Bus, Car, Truck
• Speaker Size: 10 in

Best for: LED-lit under-seat truck system.

Why it ranks #4: Its powered 10-inch aluminum enclosure measures 2.7 inches deep and supports high- and low-level inputs for varied vehicle audio systems.

A blue LED halo that lights when the vehicle starts gives Seventour’s slim 10-inch powered subwoofer a visible cabin accent alongside its bass function. The under-seat enclosure measures 2.7 inches deep, making its compact profile relevant for truck owners who want an integrated system without a separate amplifier.

The built-in amplifier keeps the subwoofer and amplification together in a 13.5-by-10.2-by-2.7-inch enclosure, which simplifies component placement under a suitable seat. High- and low-level inputs support connection to a variety of factory and aftermarket head units, giving installation options across different stereo setups. Its cast-aluminum enclosure is specified for heat dissipation, while the blue startup halo adds a visible lighting effect when the car is started.

Skip it if you prefer an unlit enclosure; Rockville SS10P offers a compact powered under-seat setup without a listed LED halo.

This Seventour suits truck owners seeking a shallow powered unit, flexible stereo inputs, and blue startup lighting in one enclosure. Check the available under-seat space against its 13.5-by-10.2-inch footprint before choosing it.

5. XPXPIAA LVZZ01

• Dimensions D x W x H: 5"D x 8"W x 5"H
• Enclosure Material: Die-Cast Aluminum
• Speaker Size: 10 in

Best for: Compact powered bass package.

Why it ranks #5: The 10-inch powered under-seat system is intended for trucks and pickups, includes a Class-D amp, and lists a two-year manufacturer warranty.

A built-in Class D amplifier and 10-inch subwoofer share one slim XPXPIAA enclosure, giving truck owners a single compact component instead of a bulky trunk box plus separate amp. The listing positions the unit for under- or behind-seat placement, with bass adjustment available from a remote.

The all-in-one format keeps the amplifier with the subwoofer, which can simplify component placement when cargo room is a priority. Its die-cast aluminum enclosure and 12-volt power specification identify it for vehicle audio use, including truck and powersports systems. The listed dimensions are 5 by 8 by 5 inches, making measurement of the intended seat area especially important; the product description also calls out remote bass tuning for adjusting low-end output without adding a separate amplifier.

Skip it if you want a 12-inch driver and a defined single-cab wedge; Rockford Fosgate R2S-1X12 provides that loaded enclosure format.

This XPXPIAA package suits buyers seeking a compact, powered bass system for a truck or other 12-volt vehicle, especially where cargo space matters. Measure carefully, since its listed 5-by-8-by-5-inch dimensions are unusually compact.

6. litillbuly SUB104

• Dimensions D x W x H: 5"D x 8"W x 10"H
• Enclosure Material: Aluminum, Plastic
• Speaker Size: 10 in

Best for: Remote-tuned slim bass.

Why it ranks #6: This slim powered 10-inch model is described for trucks and has an aluminum enclosure, but its listed dimensions do not clearly establish fit.

A supplied remote for gain, bass boost, and crossover adjustment gives the 10-inch litillbuly SUB104 more tuning access than a fixed-output under-seat box. Its 3-inch slim profile and cast-aluminum shell target space-conscious vehicle installations, while the listing specifies 1200W peak power for its bass output.

The 3-inch profile is intended to fit under car seats without using extra cabin space, making height a central fit consideration for a truck. Cast aluminum is specified for heat dissipation during extended high-power use, connecting the enclosure material to sustained operation. The remote provides control over gain, bass boost, and crossover, allowing adjustments from the listening position instead of requiring access to the enclosure each time the sound needs tuning.

Skip it if you want a listed blue startup halo; Seventour ST800 specifies LEDs that light when the vehicle starts.

Choose the SUB104 if remote tuning and a slim aluminum enclosure matter for your truck audio setup. Check the stated 10-inch height as well as the 3-inch profile against the intended mounting area.

#7 · Shallow-Mount Driver

7. Pioneer TS-A3000LS4

• Dimensions D x W x H: 3.5"D x 12"W x 12"H
• Enclosure Material: Glass Fiber Reinforced Polypropylene, Mica…
• Compatible with Vehicle Type: Car
• Speaker Size: 12 in

Best for: Shallow-mount 12-inch upgrade.

Why it ranks #7: The shallow-mount 12-inch driver measures 3.5 inches deep and offers 400 watts nominal power, but requires a suitable enclosure and system.

A 3.5-inch mounting depth is the defining advantage of Pioneer’s 12-inch TS-A3000LS4, helping add substantial driver area where a conventional-deep subwoofer may not fit. Its 400W nominal and 1500W maximum ratings pair with a reinforced cone for a bass upgrade aimed at installations with limited depth.

The 12-inch Glass-Fiber and Mica Reinforced IMPP cone is specified for rigidity and strength, supporting detailed, powerful bass rather than relying on size alone. At 3.5 inches deep, the driver offers a shallower mounting profile for constrained spaces, while its 400W nominal rating gives an installer a useful power-handling figure when matching system components. Pioneer also identifies it as a match for A-series full-range speakers, making that speaker combination a clear use case.

Skip it if you need a ready-to-install powered enclosure; Rockville SS10P includes a built-in amplifier and enclosure.

Choose this Pioneer when you want a shallow 12-inch driver and already have a system plan for amplification and enclosure. Its 3.5-inch depth helps with limited mounting space, but it is not a complete powered box.

8. LUVUMVLT Slim Subwoofer

• Dimensions D x W x H: 13.5"D x 13.5"W x 3.5"H
• Enclosure Material: Mdf
• Speaker Size: 10 in

Best for: Blue-lit under-seat bass.

Why it ranks #8: This powered 10-inch under-seat package is listed at 3.5 inches high, though its vehicle compatibility listing names cars rather than trucks.

A 3.5-inch profile and blue LED lighting make LUVUMVLT’s 10-inch powered package a space-conscious choice with a visible cabin accent. The listing specifies 1200W peak power and an under-seat form, combining a low-profile enclosure with an illuminated look for truck owners who want bass without a large box.

The 13.5-by-13.5-by-3.5-inch enclosure offers a compact shape for placing under a suitable seat, while the 10-inch speaker and 1200W peak rating describe its stated bass setup. The MDF enclosure and 12-volt input indicate a vehicle-audio installation rather than a portable speaker use. Its blue LED feature adds a visual element to the cabin, so buyers can weigh that styling against a preference for a more discreet interior.

Skip it if you need factory and aftermarket input options explicitly listed; Rockville SS10P specifies high-level and RCA inputs.

Consider this LUVUMVLT if a blue-lit appearance, 10-inch driver, and low-profile enclosure suit your truck. Its square 13.5-inch footprint is the key fit boundary, so check the full under-seat area before installation.

#9

9. BOSS Audio B12ES

• Dimensions D x W x H: 24.29"D x 7.01"W x 15.35"H
• Enclosure Material: Mdf, Plastic
• Compatible with Vehicle Type: Car
• Speaker Size: 12 in

Best for: All-in-one 12-inch bass box.

Why it ranks #9: The 12-inch amplified enclosure offers an all-in-one setup, but its compatible vehicle listing says car and its 24.29-inch depth may challenge fit.

A built-in amplifier powers the 12-inch subwoofer in BOSS Audio Systems’ B12ES, putting the main bass components in one boxed unit. That all-in-one arrangement suits space-limited vehicles that need fewer separate components, while the 600-watt subwoofer rating gives buyers a concrete power specification to consider.

The combined amplifier and subwoofer remove the need to place a separate external amplifier, which can simplify a compact installation. Its 24.29-inch depth, 7.01-inch width, and 15.35-inch height define a substantial box footprint, so truck owners should plan placement rather than assume it will fit under a seat. The 12-volt input and receiver compatibility identify its vehicle-audio role, while the listing specifies a 600-watt subwoofer powered by the built-in amp.

Skip it if you need a three-inch-high under-seat powered box; Rockville SS10P lists that slimmer profile and factory-system high-level inputs.

The B12ES suits buyers who want a 12-inch amplified box and can reserve a defined area for it in the vehicle. Its listed 24.29-inch depth is the main boundary for truck-cabin placement.

#10

10. Pioneer TS-WX106B

• Dimensions D x W x H: 9.25"D x 17.63"W x 13.5"H
• Enclosure Material: Plastic Or Metal
• Compatible with Vehicle Type: Car
• Speaker Size: 10 in

Best for: Passive sealed-box system builder.

Why it ranks #10: This passive 10-inch preloaded enclosure requires an external amplifier and is listed for cars, with no stated truck compatibility.

A sealed enclosure with a 10-inch subwoofer gives Pioneer’s TS-WX106B a ready-made box format, while its passive design leaves amplifier choice to the buyer. That separation suits truck owners who want to tailor the power and bass settings around an existing or separately selected amplifier.

The 4-ohm single voice coil provides a defined load for planning an amplifier match, and the sealed enclosure keeps the driver housed without requiring a custom box. Pioneer lists 1100W maximum power and describes the subwoofer as a compact 10-inch option; the 17.63-by-13.5-by-9.25-inch dimensions still need a suitable placement area. Because it is passive, the system requires an external amplifier, giving buyers control over that component while adding an installation step.

Skip it if you need an amplified unit without a separate amp; Rockford Fosgate P300-10T includes a built-in 300-watt Class-D amplifier.

This Pioneer suits truck owners building a system around a chosen external amplifier and a sealed 10-inch box. Its passive design adds a component and matching step, and the enclosure dimensions need a suitable mounting location.
