Under-seat bass, factory integration, radio upgrades, complete systems and electrical work—all built around seat space, storage, factory features and how the truck is actually used.
Sometimes it is under-seat space. Sometimes it is factory integration, electrical support or getting serious bass without giving up the way the truck gets used. These are real SMS solutions.
SMS built the custom enclosure for two KICKER CompQ 10-inch subwoofers, then it was sent to Kandyman Mike to be paint matched to the truck's OEM exterior color for the client.
This 2025 Ram RHO kept the factory Harman Kardon system and added a KICKER Dodge loaded dual 10-inch L7T enclosure powered by a KICKER LX3000.1.
We built this enclosure ahead of the install for two KICKER Solo X 8-inch subwoofers in a 2022 Denali.
This 2014-up Chevy under-seat box was built for four 8-inch subwoofers. The client wanted to stain it themselves, so we left it in the bare-wood finish they needed.
The Ram received a CarPlay-ready Jensen with a 10.1-inch screen. The door and rear-cab speakers were upgraded to KICKER KS coaxials.
The 2022 GMC Duramax Bose system was integrated into the aftermarket audio system with an ARC Audio FALCON handling digital signal processing and system amplification.
The customer was frustrated with an install done elsewhere. SMS replaced the Hertz coaxials, retuned the DSP and set the amplifier gain structure.
The stock radio was upgraded to a Sony XAV-AX8100 with Apple CarPlay and Android Auto while retaining the steering-wheel functions.
Not much room under the seat in this 2023 F-150 Extra Cab, so the bass system was built around two 6.5-inch subwoofers that fit the space we actually had.
A Mosconi DSP was used with the factory Bose signal in this 2020 Chevrolet Silverado before the upgraded system was tuned.
This 2013 Chevy 3500 Dually received a custom-built enclosure housing a KICKER L7 8-inch subwoofer.
This Ram needed serious bass without giving up the under-seat layout. We built the ported enclosure around KICKER Solo L7X 8-inch subwoofers and the space available in the truck.
The F-150 enclosure was built to house four MMATS Dreadnaut 8-inch subwoofers powered by a KICKER Warhorse. An LMI seat lift is required.
Four 8s in a 1990s Nissan Hardbody Extended Cab. The box was built around the room available in the truck.
The C10 uses a Sony XAV-AX8100, Mosconi Atomo tuned with GA-Barnie to a custom house curve, OFC wiring and RCA interconnects, three MMATS 6.5-inch Dreadnaut subwoofers on an LSX 2000.1, and eight MMATS PA 6.5-inch coaxials on an LSX 1400.4.
This F-250 came in for the subwoofer amplifier install. We ran the power and ground with OFC cable, then routed and terminated the wiring cleanly around the equipment.
Four 8s had to fit under the seat, but this one was never supposed to look like a plain carpeted box. We built the enclosure around the available space, then finished it with LED lighting, acrylic and inlay work, Denali vinyl and laser engraving.
This is progress on Jeff Wartberg's sixth-order blow-through enclosure in a Nissan Hardbody sprayed by Kandyman Mike. The audio build is by SMS Car Audio.
There was no reason to waste usable cab space. We built the amplifier rack to live behind the seat in this 2006 Chevy Silverado Extended Cab.
Oscar's Chevy truck was getting ready to run its new bass setup powered by three Vault Power NA59 HP sodium batteries.
This 2012 Silverado came in for more than one piece. We handled the truck as a complete audio-system upgrade so the system could work together instead of being a pile of unrelated parts.
Photos show the install. Video lets you see the system, the truck and the finished result in action.
