Products, installation, fabrication, and tuning from one shop.
We can sell you the right product, install it correctly, fabricate what the vehicle needs, and tune the finished system—but we first listen to what you want it to do.
What customers can buy from SMS.
Buy the product, add the service, or use both.
SMS sells equipment online and over the counter. Installation, fabrication, integration, and tuning are available when the customer wants the shop to complete more of the job.

About SMS Car Audio
SMS Car Audio is a 12-volt mobile electronics shop in Marrero, Louisiana, focused on complete system planning, clean installation, factory integration, DSP tuning, custom fabrication, subwoofer enclosures, electrical support, and vehicle-specific audio.
The shop’s approach is built around one principle: equipment should be chosen for the vehicle and installed as part of a complete system. Signal quality, speaker placement, power, enclosure design, electrical capacity, fabrication, and tuning all affect the finished result.

Where Music Matters
A successful system should fit the vehicle, retain important factory functions where possible, perform reliably, sound controlled, and remain serviceable after installation. SMS helps customers understand the decisions behind the build instead of treating each product as an isolated purchase.
- Car audio system planning and installation.
- DSP tuning, factory radio integration, and signal correction.
- Speaker, amplifier, subwoofer, wiring, battery, and charging-system upgrades.
- Custom enclosures, amp racks, panels, adapters, lighting, and acrylic work.
- Jeep, motorcycle, SXS, Slingshot, marine, truck, and specialty-vehicle systems.
- 3D scanning, 3D printing, CNC, laser cutting, and vehicle-specific fabrication.
How SMS Approaches a Build
The same product can perform very differently in two vehicles. Factory processing, speaker locations, cabin acoustics, enclosure space, available current, mounting quality, and tuning all change the result. SMS reviews those conditions before finalizing the equipment list.
- Understand the vehicle. Identify the factory radio, amplifier, speaker layout, electrical system, space, and retained features.
- Define the result. Determine whether the priority is clarity, staging, bass, overall output, open-air projection, appearance, or a combination.
- Match the system. Select speakers, amplification, processing, subwoofers, wiring, electrical support, and fabrication that work together.
- Install for reliability. Address mounting, protection, grounding, cooling, wire routing, fitment, and service access.
- Set up and tune. Complete gain structure, crossovers, levels, phase, EQ, time alignment, and bass blending as required.
Specialized Vehicle Work
Jeeps, motorcycles, powersports vehicles, boats, trucks, and custom builds create different challenges. Wind and road noise, weather exposure, limited mounting space, charging capacity, vibration, and listening position can change the correct speaker, amplifier, enclosure, and tuning strategy.
- Jeep Audio Installation
- Motorcycle Audio Installation
- Powersports, SXS & Slingshot Audio
- Marine and Weather-Resistant Audio
Custom Fitment and Fabrication
Some projects require more than an off-the-shelf adapter or enclosure. SMS uses measurement, scanning, printing, CNC, laser, acrylic, and custom construction when the vehicle needs a stronger mounting solution, better use of space, a cleaner finish, or a repeatable custom part.
Products and Authorized Dealer Support
SMS works with product lines that support different system goals, budgets, vehicle types, and installation paths. A recommendation is based on application, fitment, power, reliability, and tuning requirements—not the brand name alone.
