Best Subs For A Single Cab Truck: 10- and 12-Inch 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
• Compatible with Vehicle Type: Truck
• Speaker Size: 12 in
• Enclosure Material: Medium Density Fiberboard

Best for: Seat-travel-limited single cabs.

Why it ranks #1: Its loaded 12-inch sealed wedge is explicitly optimized for single-cab trucks with limited seat travel and handles 250 watts RMS at a 2-ohm load.

The wedge-shaped sealed enclosure is optimized for single-cab trucks with limited seat travel, helping add a 12-inch subwoofer where a traditional woofer may not fit. Its loaded, internally wired design presents a 2-ohm amplifier load, so buyers can plan around a defined connection and power-handling specification.

At 31.3 inches wide and 8.3 inches deep, the enclosure offers a measured footprint to compare with the space behind a truck seat. The wedge shape specifically addresses limited seat travel, while the sealed enclosure comes loaded with a 12-inch dual voice coil subwoofer. Internal wiring creates a 2-ohm amplifier load, and the stated 250 watts RMS handling gives buyers a concrete figure for matching amplification. Its 5/8-inch MDF construction and carpet covering complete the enclosure.

Skip it if you have less than 31.3 inches of width behind the seat; the narrower Pioneer TS-A2000LB measures 9.88 inches wide.

This suits a single-cab truck owner seeking a loaded 12-inch subwoofer and a wedge enclosure for restricted seat travel. Measure the available width and depth first, and match the amplifier to its 2-ohm load and 250-watt RMS rating.

#2 · Best 10-Inch Loaded Option

2. Rockford Fosgate R2S-1X10

• Dimensions D x W x H: 16.5"D x 23"W x 8.3"H
• Compatible with Vehicle Type: Car
• Speaker Size: 10 in
• Enclosure Material: Wood

Best for: Slim single-cab 10-inch bass.

Why it ranks #2: The loaded 10-inch wedge is designed for single-cab trucks with limited seat travel, and its 200-watt RMS rating suits buyers seeking a smaller driver.

The wedge enclosure is optimized for single-cab trucks with limited seat travel, making this loaded 10-inch subwoofer an option when a conventional box is too bulky. Its internal wiring creates a 2-ohm amplifier load, and the stated 200-watt RMS handling gives buyers a practical basis for matching an amp.

This sealed, loaded enclosure combines a 10-inch subwoofer with an internally wired 2-ohm load, which simplifies identifying the load presented to a compatible amplifier. The 200-watt RMS and 400-watt maximum ratings help guide power matching. Its wedge design targets single-cab trucks with limited seat travel, while 5/8-inch MDF construction and a high-density carpet covering provide the specified enclosure materials and finish. The listed dimensions are 23 inches wide, 8.3 inches high, and 16.5 inches deep, so check the actual available space carefully.

Skip it if you have less than 16.5 inches of available depth; the Alpine SS-SB10 enclosure is listed as 4.5 inches deep.

This suits a single-cab owner seeking a loaded 10-inch subwoofer with a defined 2-ohm load and wedge-style enclosure. The listed 16.5-inch depth deserves particular attention, so compare the dimensions with the truck’s actual behind-seat space.

#3 · Best Single-Sub Amp Package

3. Harmony Audio Kicker C12 Package

• Dimensions D x W x H: 7.5"D x 15"H
• Compatible with Vehicle Type: Truck
• Speaker Size: 12 in

Best for: Single-sub regular-cab package.

Why it ranks #3: This regular-standard-cab package includes a single 12-inch Kicker sub, enclosure, and mono amplifier, providing more of the required system in one bundle.

The package pairs a Kicker 12-inch Comp subwoofer with a Harmony Audio mono amplifier and a standard-cab truck box, giving buyers a sub-and-amplifier combination in one purchase. The enclosure’s 5-3/4-inch mounting depth and 0.80-cubic-foot air space provide specific figures for checking behind-seat clearance.

The single-sub enclosure measures 20 inches wide and 15 inches high, with depth varying from 5 to 7.5 inches, so compare its full shape with the available cabin space. A 5-3/4-inch mounting depth is another useful clearance measurement. The included Kicker C12 is rated at 150 watts RMS and is a 4-ohm, single-voice-coil subwoofer; the included HA-A400.1 mono amplifier is listed as 1-ohm stable. Confirm the system’s intended wiring and amplifier settings before installation.

Skip it if you want a subwoofer enclosure without a bundled amplifier; the KICKER 43C124-N package lists a single sub and box.

This package fits a buyer assembling a single-sub system for a regular-cab truck who wants the subwoofer, enclosure, and mono amp together. Check the 20-inch width, stepped depth, and amplifier wiring requirements against the truck and audio system.

4. Kicker C12 Single-Sub Bundle

• Dimensions D x W x H: 7.5"D x 20"W x 15"H
• Compatible with Vehicle Type: Truck
• Speaker Size: 12 in

Best for: Simple single-12 truck bundle.

Why it ranks #4: The truck-specific bundle pairs a sealed single-12-inch enclosure with a 4-ohm, 150-watt RMS Kicker sub; it does not list an amplifier.

This KICKER bundle combines a 12-inch Comp C12 subwoofer with a single-sub truck enclosure, giving regular-cab buyers the core speaker-and-box pairing together. The sealed enclosure provides 0.80 cubic feet of air space, while the sub’s 150-watt RMS rating and 4-ohm single voice coil clarify key system-matching details.

The 20-inch-wide enclosure is specified for a regular standard-cab truck, and its 7.5-inch listed depth helps buyers check available installation space. The sealed box has 0.80 cubic feet of air space and a 5-3/4-inch mounting depth. Its included KICKER C12 is a 4-ohm, single-voice-coil subwoofer rated at 150 watts RMS and 300 watts peak. Because the package listing identifies a subwoofer and enclosure rather than an amplifier, buyers can select amplification to suit the stated load and power rating.

Skip it if you need an amplifier included; the Harmony Audio single-12 package lists a mono amp with its subwoofer and enclosure.

This bundle suits a regular-cab truck owner who wants a KICKER 12-inch sub and sealed enclosure as the starting point for a system. Allow for a separate amplifier and check the 20-inch width and mounting depth before installation.

#5 · Best Single-10-Inch Box

5. Q Power TW10S Enclosure

• Dimensions D x W x H: 7.5"D x 20.3"W x 15.9"H
• Compatible with Vehicle Type: Car, Truck
• Speaker Size: 10 in
• Enclosure Material: Wood, Fabric

Best for: Single 10-inch empty truck box.

Why it ranks #5: This sealed 10-inch enclosure is described for behind-seat single- or extended-cab installation, with 7.5-inch depth and 0.88 cubic feet of airspace.

The Q Power TW10S provides a sealed single-10-inch enclosure with 0.88 cubic feet of internal air space, letting buyers choose their own compatible subwoofer for a behind-seat truck installation. Its 7.5-inch depth and 20.3-inch width give a clear starting point for checking cabin fit.

This is an enclosure with a single 10-inch cutout, not a loaded subwoofer package, so the buyer selects and installs the driver separately. The sealed 0.88-cubic-foot interior is specified for tight, accurate bass response, while the 7.5-inch depth is intended for behind-seat placement in single- or extended-cab trucks. Its 5/8-inch MDF construction is described as reducing panel flex and resonance. A carpet covering gives the box a finished surface, and the 20.3-inch width helps assess the available span.

Skip it if you want a loaded enclosure; the Rockford Fosgate Prime R2S-1X10 includes a 10-inch subwoofer in its box.

This is for a truck owner who already has, or plans to choose, a compatible 10-inch subwoofer for a sealed behind-seat box. Check the 20.3-inch width and 7.5-inch depth, and account for the separate driver purchase and installation.

#6 · Best Dual-10-Inch Box

6. Q Power HD210 Truck Box

• Dimensions D x W x H: 13.5"D x 49"W x 8.5"H
• Compatible with Vehicle Type: Truck
• Speaker Size: 10 in
• Enclosure Material: Wood

Best for: GM/Chevy dual-10 cab box.

Why it ranks #6: The dual-10-inch enclosure is specifically designed for GM/Chevy single cabs and uses a 1-inch MDF face, but its 49-inch width needs careful checking.

The Q Power HD210-TRUCK is specified for GM/Chevy single cabs and provides two 10-inch subwoofer openings, giving buyers a dual-driver enclosure for that stated application. Its 1-inch MDF face and 3/4-inch MDF frame are thicker than the 5/8-inch construction described for many boxes, while each sub has 1.15 cubic feet of air space.

At 49 inches wide, 13.5 inches deep, and 8.5 inches high, this dual enclosure needs a broad installation area behind the seat. The listed GM/Chevy single-cab fit is useful when narrowing vehicle compatibility, but the dimensions still need to be checked against the cabin. A 1-inch MDF face and 3/4-inch MDF frame provide the specified construction, and 1.15 cubic feet per sub identifies the air space available to each of the two 10-inch drivers. The enclosure listing does not include subwoofers.

Skip it if you need drivers included; the Harmony Audio dual-12 package includes two subwoofers and a mono amplifier with its enclosure.

This suits a GM/Chevy single-cab owner planning a dual-10 setup and selecting subwoofers separately. Its 49-inch width is a major fit consideration, so measure the installation span and account for both drivers before choosing the enclosure.

7. Harmony Audio Dual C12 Package

• Dimensions D x W x H: 16"D x 50"W x 13"H
• Compatible with Vehicle Type: Truck
• Speaker Size: 12 in
• Enclosure Material: Mdf

Best for: Dual-sub regular-cab setup.

Why it ranks #7: The regular-standard-cab bundle includes two 12-inch subs, a mono amplifier, and wiring; its 49-inch listed width may be restrictive in a single cab.

Two Kicker 12-inch Comp C12 subwoofers anchor this regular-cab package, giving buyers a dual-driver enclosure and a bundled mono amplifier. The box lists 0.96 cubic feet of air space per sub and a 49-inch width, letting truck owners evaluate both enclosure volume and the substantial span required.

The enclosure is specified for a regular standard-cab truck and measures about 49 inches wide, so the available behind-seat span is a key installation check. Its 5-5/16-inch mounting depth and 0.96 cubic feet per sub provide further fit and enclosure details. The package includes two 150-watt RMS Kicker C12 subwoofers and a Harmony Audio HA-A800.1 mono amplifier. A 5/8-inch MDF box and included 4-gauge amp wiring kit round out the listed package, reducing the need to source those components separately.

Skip it if you have less than 49 inches of installation width; the Harmony Audio single-12 package uses a 20-inch-wide enclosure.

Choose this package if a regular-cab truck has room for a wide dual-12 enclosure and you want the two subs, mono amplifier, and wiring kit together. Its nearly 49-inch span is a firm fit consideration before planning installation.

8. Alpine SS-SB10

• Dimensions D x W x H: 18.5"D x 12.5"W x 4.5"H
• Compatible with Vehicle Type: & SUVs, Select Cars, Truck
• Speaker Size: 10 in
• Enclosure Material: Plastic

Best for: Ultra-shallow Alpine installation.

Why it ranks #8: This truck-compatible loaded 10-inch enclosure is only 4.5 inches deep and handles up to 300 watts RMS, though it is not identified specifically for single cabs.

At just 4.5 inches deep, Alpine’s preloaded 10-inch S-Series enclosure targets installations where behind-seat clearance is especially tight. Its front-mounted magnet helps keep the enclosure shallow, while four adjustable foam-padded steel brackets provide mounting flexibility across the listed vehicle applications, including trucks.

The SS-SB10 combines a 10-inch subwoofer with a slim enclosure measuring 18.5 inches long, 12.5 inches wide, and 4.5 inches deep. That shallow profile can help preserve cabin space where deeper boxes are difficult to place. A front-mounted magnet contributes to the low-profile layout, and the four adjustable, foam-padded steel brackets give installers options for securing it in different locations. The 2-inch voice coil and neodymium magnet are listed alongside power handling up to 300 watts RMS, useful details for system planning.

Skip it if you want a deeper behind-seat box; the Q Power TW10S lists 7.5 inches of depth and 0.88 cubic feet of air space.

This fits a truck owner prioritizing a shallow, preloaded 10-inch enclosure and adjustable mounting brackets. Check the 18.5-by-12.5-inch footprint and select a location that accommodates the brackets as well as the 4.5-inch depth.

9. Rockville SS10P Powered Sub

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

Best for: Powered under-seat installation.

Why it ranks #9: The powered 10-inch system includes an 8-gauge wiring kit and is listed for cars and trucks; its slim under-seat format offers an alternative to behind-seat boxes.

The Rockville SS10P combines a powered 10-inch subwoofer with a 3-inch-thick enclosure, helping add bass under a truck seat without giving up much cabin space. High-level inputs support connection to factory or aftermarket systems, and auto turn-on detects an audio signal to switch on its built-in amplifier.

Because this is an active powered subwoofer, the enclosure includes its own amplifier rather than requiring a separate sub amp. Its 3-inch thickness is specified for under-seat placement, while the listed overall dimensions are 16 by 12 by 5 inches; measure the complete footprint and clearance before installation. High-level inputs can connect to factory systems without preamp outputs, and the smart turn-on circuit responds to the audio signal. The package also includes an 8-gauge wiring kit with copper RCA cable.

Skip it if you require a stated RMS power rating; the Alpine SS-SB10 lists handling up to 300 watts RMS.

This suits a truck owner seeking a powered, space-saving under-seat subwoofer with high-level input options and included wiring. Verify the complete 16-by-12-by-5-inch dimensions against the seat area, not just the stated enclosure thickness.

#10

10. Pioneer TS-A2000LB

• Dimensions D x W x H: 5.13"D x 9.88"W x 13.75"H
• Compatible with Vehicle Type: Car
• Speaker Size: 8 in
• Enclosure Material: Rubber, Steel Mesh, Carpet, [possibly Plastic…

Best for: Compact Pioneer-system upgrade.

Why it ranks #10: This compact, loaded 8-inch subwoofer measures 5.13 inches deep and handles 250 watts RMS, but its vehicle compatibility is listed as car rather than truck.

Pioneer’s 8-inch sealed subwoofer measures just 5.13 inches deep, helping add bass where a larger enclosure would take up too much cabin space. Its 250-watt nominal power handling and reinforced IMPP cone offer a defined power figure and a rigid-cone design for buyers planning a compact system.

The preloaded sealed enclosure measures 9.88 inches wide, 13.75 inches high, and 5.13 inches deep, making those dimensions useful when checking a tight installation area. Its 8-inch driver handles 250 watts nominal power, with 700 watts maximum listed, so amplification can be selected with those ratings in mind. The Glass-Fiber and Mica Reinforced IMPP cone is specified for rigidity and strength. Removable feet and cushions allow adjustment to the mounting arrangement, while the steel mesh grille covers the front.

Skip it if you prioritize a larger driver; the Rockford Fosgate Prime R2S-1X12 has a 12-inch subwoofer in a shallow enclosure.

This is a fit for a Pioneer A-series owner or compact-cab buyer seeking an 8-inch preloaded sealed subwoofer with mounting adjustments. Its small footprint is useful when space is tight, but consider a larger driver if that is your priority.
