Signal and control
DSP & OEM Integration
Factory-signal assessment, interfaces, processor installation, channel routing, calibration, and measured tuning.
Start With the Job. Leave With One Clear Next Step.
Some customers need one part. Some need a clean installation. Others need the factory signal, speakers, bass, power, fabrication, and tuning planned as one system. This page takes you directly to the right department without sending every question to the same contact form.

How work moves through the shop
The product comes after the vehicle and the goal.
A useful recommendation starts with what the vehicle has now, what must remain functional, and what the finished system needs to do. That keeps the quote, equipment, labor, and final result pointed in the same direction.
- 01Identify the vehicle
Year, model, trim, factory audio package, current equipment, usable space, and the features that must be retained.
- 02Define the result
Clarity, output, bass, sound quality, appearance, cargo use, weather exposure, budget, and whether the build happens now or in stages.
- 03Verify the system requirements
Signal, speaker locations, enclosure, channels, power, electrical support, mounting, fabrication, controls, and service access.
- 04Choose the right scope
Buy the verified products, add professional installation, or have SMS deliver the complete installed and tuned system.
Choose the result
Go straight to the information behind the upgrade.
Each route explains the decisions that matter before it asks you to buy equipment or schedule work.

Open the speaker-system guide → Factory integrationKeep the factory source and build from a signal that has been verified.Premium factory amplifiers, active channels, ANC, feature retention, signal behavior, routing, DSP, and tuning.
Open the factory-signal guide → Bass systemBuild the enclosure, woofer, power, and vehicle space together.True net volume, sealed or ported alignment, loading, amplification, electrical support, integration, and cargo use.
Open the bass-planning guide → High outputGet loud and stay clear with the right bandwidth and protection.Efficient mids, high-frequency drivers, placement, crossover protection, power, electrical support, and tuning.
Open the high-output guide → Source and safetyAdd CarPlay, Android Auto, cameras, and useful vehicle integration.Radio fitment, retained controls, warning tones, cameras, factory amplification, interfaces, and system expansion.

Service and information hub
Every department has a direct route.
Use the guide when you need to understand the job. Use the product link when the system is already planned. Use the service request when you are ready for SMS to perform the work.

System already planned?
Choose how far SMS takes the project
The same goal can require three different levels of service.
01 · Product onlyBuy equipment for a system that is already planned.
Use this route when fitment, signal, channels, enclosure, power, electrical, installation, and tuning requirements are already known.
Shop products → 02 · Add professional serviceHave SMS install, fabricate, integrate, or tune a defined job.Send the exact vehicle, current equipment, requested work, photos, and the result you expect from the service.
Request professional service → 03 · Complete systemPlan the equipment and labor as one finished project.Use this route when the factory signal, speaker layout, bass, power, electrical, fabrication, installation, and tuning need to work together.

Built around the application
Use the guide for the vehicle you are building.
Noise, exposure, speaker locations, available space, charging capacity, and service access change the equipment and installation plan.
Where Music Matters
Tell us the vehicle, the problem, and the result.
SMS can supply the equipment, perform a defined service, or plan and deliver the complete installed system. The right starting point depends on how much of the design is already settled.
