Before You Buy

Should I buy parts first or talk to SMS first?

If SMS is installing it, tuning it, wiring it, fabricating for it, or building around it, contact the shop before checkout. The best result comes from matching the vehicle, factory signal, product path, wiring, DSP, enclosure, electrical support, labor, and tuning before money is spent.

Why do some ARC Audio and Kicker products not show prices?

Some ARC Audio and Kicker products require a quote, an appointment, or in-store handling because of authorized dealer pricing policies. Do not treat a hidden price as a broken product page; contact SMS for the correct purchase path.

Can I buy Recoil, Beyma, and AudioCenter products online?

Recoil Audio and AudioCenter products can be purchased online where checkout is enabled. Beyma products require direct contact with SMS for current pricing, availability, and purchase options. Some items can still require fitment help, shipping confirmation, special-order handling, or installation planning.

Can SMS help me choose products?

Yes. SMS can match speakers, amplifiers, subwoofers, DSP, radios, cameras, batteries, wire, lighting, and fabrication parts to the vehicle and goal. Products purchased through SMS are easier to verify, install, support, and warranty through the shop.

Why not just buy from a marketplace?

Marketplace listings do not know your vehicle, factory audio package, wiring needs, signal path, enclosure space, battery support, or tuning goal. SMS combines product sales with local installation, 12-volt experience, fabrication capability, and tuning knowledge.

Installation and Shop Policy

Does SMS install customer-supplied equipment?

SMS generally does not install products that were not purchased through SMS. Exceptions are shop-approved only and may require inspection, testing, additional labor, adapters, wiring correction, or troubleshooting. Customer-supplied products do not receive the same warranty and support path as products purchased through SMS.

Do I need an appointment?

Yes, for installations, DSP tuning, fabrication, lighting, custom enclosures, vehicle inspections, system planning, and larger quote sessions. Some quick product questions can be handled by call, text, or email.

What should I send before booking?

  • Vehicle year, make, model, trim, and factory audio package.
  • Photos of the radio, doors, dash, trunk, cargo area, battery area, saddlebags, or current wiring when useful.
  • Current equipment that is installed or already purchased.
  • Your goal: cleaner sound, louder output, more bass, better staging, cameras, lighting, reliability, OEM retention, or full custom work.
  • Budget range and whether SMS is supplying the equipment.

System Planning

How do I choose the right speakers?

Speaker choice depends on vehicle fitment, amplifier power, listening goal, mounting depth, adapters, door treatment, crossover plan, and whether the system will stay passive or use DSP tuning.

Should I upgrade speakers or the amplifier first?

Many systems perform best when speakers, amplifier power, installation, DSP, and tuning are planned together. Random speaker swaps can expose weak factory power, bad signal, poor mounting, or factory processing problems.

What size subwoofer is best?

Subwoofer size depends on space, enclosure design, amplifier power, vehicle cabin, final impedance, and the customer’s bass goal. The enclosure is just as important as the subwoofer model.

DSP, OEM Integration, and Tuning

What is a DSP?

A DSP gives control over EQ, crossovers, time alignment, output levels, signal routing, staging, imaging, and subwoofer blending. It is often the difference between installed parts and a finished system.

Do I need a DSP?

You may need DSP if the vehicle has factory integration, premium factory audio, multiple amplifiers, active channels, difficult speaker locations, or if you want better staging, control, and tuning accuracy.

Cameras, Lighting, CNC, Laser, and Fabrication

Does SMS install dash cameras and backup cameras?

Yes. Camera work depends on the vehicle, radio compatibility, trigger wiring, retention needs, camera location, cable routing, and final testing.

Does SMS do custom fabrication?

Yes. SMS supports 3D scanning, 3D printing, CNC, laser work, acrylic panels, speaker rings, adapters, subwoofer enclosures, Lit FX panels, and vehicle-specific custom work.

Are custom panels and built-to-order enclosures returnable?

Custom, built-to-order, vehicle-specific, laser-cut, CNC-cut, acrylic, lighting, enclosure, and fabrication work is generally final once approved, ordered, designed, cut, fabricated, assembled, or started.

Amplifiers, Batteries, and Electrical

What is RMS power?

RMS power is the usable continuous power rating. SMS plans systems around real power, impedance, speaker load, wiring, fuse protection, gain structure, and safe installation rather than peak or max claims.

Do I need a battery or alternator upgrade?

Battery and charging support matter when the system demands more current than the vehicle can comfortably supply. Larger amplifiers need correct wire size, fuse protection, grounding, battery reserve, and voltage support.
