JL Audio SB-F-150-SCDBL/12TW3/BK
Stealthbox® for 2009-Up Ford F-150 SuperCrew / 2017-Up SuperDuty Crew Cab
The Ford F-150 is an American icon with impressive hauling capabilities and a spacious interior, especially in SuperCrew configurations. Unfortunately, Ford’s factory sound systems leave a lot to be desired in the low frequency department.
Our Stealthbox® for F-150 SuperCrew and SuperDuty Crew Cab trucks fills your truck with stunning sub bass output and quality, with no intrusion on cab space. Featuring an all-fiberglass, sealed enclosure design, this Stealthbox® houses two of our revolutionary 12TW3 thin-line subwoofers and installs neatly under the rear seat, without compromising rear seat comfort.
The Hard Data: Contains two 12TW3-D8 subwoofers in a sealed enclosure. 800 watt power handling. Wired for 2 ohm mono. Installs under rear bench seat and requires removal of under-seat storage tray, if so equipped. Installation requires removal of OEM “subwoofer”, if so equipped. Does not affect folding or reclining of seat.
JL Audio 12TW3-D8
TW3 12-inch Subwoofer Driver (400 W, dual 8 Ω voice coils)
Building on the core technology of our TW5 thin-line subwoofers, the new TW3’s deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3’s.
To allow this remarkable feat to be achieved, JL Audio’s patented thin-line woofer technology compresses the architecture of the TW3’s using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of the large motor structure further forward in the speaker than with conventional designs.
TW3’s are optimized for small enclosures and offer our tab-ear mounting design to maximize cone area within their mounting footprints. We know you’re going to love working with these amazing subwoofer drivers.
Deep, powerful and accurate JL Audio bass is now possible in more applications than ever.
- Very shallow mounting depth (3.25 / 3.50 Inches)

1x Audison SR 1.500.2 D-Class Mono Bass Amplifier 1000 Wrms X 1 At 1-Ohms (SR1.500.2)
SR 1.500 - MONO AMPLIFIER 1x500W
We are proud to present the renovated SR 1.500 (1000 W 1 Ω) introduced back in 1988 and constantly updated with the best technologies available. The Audison design team, headquartered in the Potenza Picena (Italy), spent a long time planning and perfecting the new SR line, taking full advantage of the features that the most recent amplification devices available today are equipped with. After numerous listening tests in a double-blind configuration on a significant sample of professionals and enthusiasts, the R&D team decided to adopt a new D-class technology called ADT (Audison D-Class Technology) for the whole range, which made it possible to reduce the size of the amplifiers considerably, totally preserving the audio performance that characterize each Audison project. As for the electronics design, the Audison style center has taken care of every aesthetic and functional detail, obtaining a compact amplifier made of extruded aluminium with rounded corners that ease the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, internal cooling fans are not necessary, which are often cause of noise and dust accumulation.
Features -
• ADC (Audison D-Class) Technology 1Ω stable output stage ensuring high audio performance in a compact size.
• Extruded aluminum compact design with fan less convection cooling system.
• Built-in USS (Universal Speakers Simulator).
• Balanced high-noise rejection input speaker-In (for OEM head units) and RCA-In (for Aftermarket head units) inputs.
• ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/ disabled, with Speaker-In inputs).
• Pre-outs, also available when using Speaker-In level inputs.
• Bass Boost (50 Hz) adjustable to 12 dB, to increase the subwoofer punch.
• 24 dB continuous adjustable (50 to 250 Hz) Lo-Pass subwoofer filter.
1x Audison bit Ten Signal Interface Processor with 4 Channels In and 5 Out (bit-Ten)
bit Ten - SIGNAL INTERFACE PROCESSOR
bit Ten is a multi-function digital processor featuring analog input, capable of transforming ordinary OEM or after-market system into a high-performance system. Provided with a 32 bit, 147 MHz clock speed DSP as well as 24 bit A/D and D/A converters, bit Ten is controlled by a software especially developed for signal treatment according to the vehicle acoustic peculiarities. Setting the parameters of each input single channel, setting the delays according to the listening position, adjusting crossovers and equalizers for each of the 5 output channels; all of these operations can be managed by the PC. Thanks to the integration of the USS technology, the bit Ten can also be connected to headunits featuring the “speaker load detection” circuit that would otherwise mute the audio signal output. During the installation phase, after converting the analog signal into digital, bit Ten automatically reconstructs a digital full-bandwidth stereo signal; de-equalizes the frequency response and, if necessary, reconstructs the central and subwoofer channels.The user can configure the output mode of each channel relative to the installed system.
Features -
• Audio DSP and converters 32 bit Cirrus Logic (Clock speed: 147 MHz) Digital Signal Processing chip and A/D D/A converters working in PCM at 48 kHz with 24 bit resolution. The processor speed allows the user to hear and verify in real time the changes applied during the tuning.
• Audio Inputs 4 independent high-level channels with automatic summing capability and USS (Universal Speakers Simulator), the technology that allows bit processors to work with headunits featuring the “speaker load detection” circuit; 1 analog low-level stereo auxiliary input; 1 high-level momentary audio interrupt input (with priority) on Phone Mute cable (settable through PC).
• Audio Outputs 5 independent analog PRE channels featuring adjustable level.
