DSP Tuning, OEM Integration & Factory Sound Upgrades
SMS Car Audio is a 12-volt specialist shop that measures, installs, and tunes complete vehicle audio systems. We work with ARC Audio, Mosconi, factory integration platforms, GA-Barnie binaural measurement, RTA microphones, and hands-on industry training to solve the signal and tuning problems that product swaps alone do not fix.
Modern factory systems can apply EQ, bass reduction, active crossovers, channel delays, all-pass filters, center-channel processing, and volume-dependent changes before the signal ever reaches an aftermarket amplifier. SMS checks the signal first, builds the correct routing and amplification plan, then tunes the finished system in the vehicle.

Measured Tuning, Not Guesswork
SMS uses measurement and listening together. Depending on the system, that can include RTA measurements, left/right response checks, GA-Barnie binaural measurement, polarity and phase verification, gain-structure testing, crossover analysis, and subwoofer integration.
- Factory signal and clipping-point verification.
- Input routing, summing, load support, and retained-feature checks.
- Safe crossover setup for tweeters, midrange, midbass, rear fill, and subwoofers.
- Level matching, time alignment, equalization, phase, and bass integration.
- Preset planning for daily listening, open-air use, or higher-output operation when supported.
- Final listening verification after the measurements are complete.
Why the Installation Still Matters
DSP cannot repair a weak speaker mount, clipped input, poor ground, undersized power wire, incorrect enclosure, unsafe crossover, or bad polarity. SMS treats signal, installation, amplification, electrical support, enclosure design, and tuning as one system.
ARC Audio and Mosconi DSP Specialists
SMS regularly works with ARC Audio and Mosconi processing platforms because both lines offer serious routing, integration, amplification, and tuning control. The correct processor or DSP amplifier depends on the factory signal, required channel count, speaker layout, amplifier plan, controller needs, and future expansion.

Buy the Equipment or Book the Complete Job
Products can be purchased from SMS without local installation. Online checkout is available where allowed, and many products can be shipped nationwide. Restricted or in-store brands can be purchased by contacting SMS with the exact model and shipping or pickup request.
For local installs and tuning, send the vehicle year, make, model, trim, factory audio package, current equipment, speaker layout, subwoofer setup, sound goal, and budget range.
Detailed system design and fitment research are reserved for customers purchasing equipment from SMS or booking installation and tuning. SMS does not provide full system design around a third-party shopping list that will be purchased elsewhere.
