Warranty & Returns

Product support based on the item, condition, and purchase path.

Warranty and return handling can differ for standard products, installed products, special orders, closeout items, built-to-order enclosures, and custom fabrication.

Warranty and Return Policy

This is the current warranty and return policy for SMS Car Audio. It explains product returns, warranty support, final-sale items, custom work, special orders, installation labor, diagnosis, and products not purchased through SMS.

SMS wants customers to buy the right products, plan the right installation, and understand the support path before checkout. If SMS is installing it, contact the shop before ordering.

Start With the Right Product

If SMS is installing it, ask before checkout. Returns, delays, and mismatched parts are easier to avoid when the product, wiring, adapters, DSP, enclosure, electrical support, and labor plan are matched before purchase.

  • Vehicle year, make, model, trim, and factory audio package matter.
  • Factory radio signal, factory amplifier behavior, speaker fitment, amplifier channels, enclosure space, and electrical support matter.
  • Products purchased through SMS are easier to verify, support, install, and warranty through the shop.

Product Return Guidelines

  • Eligible new products may be considered for return only when they are unused, uninstalled, complete, in original packaging, and approved by SMS before being returned.
  • Products that have been installed, powered, wired, cut, modified, mounted, tuned, programmed, scratched, damaged, or used may not be eligible for return.
  • Items missing boxes, manuals, accessories, hardware, harnesses, adapters, trim pieces, remotes, serial information, or packaging may be refused or subject to reduced credit if accepted.
  • Do not ship or drop off a return without contacting SMS first. Items returned without approval may be refused.
  • Shipping charges, vendor-direct charges, special-order charges, and payment processing costs may not be refundable once incurred.

Final Sale and Limited-Return Items

  • Open-box, used, clearance, closeout, demo, scratch-and-dent, previously installed, or final-sale items.
  • Custom subwoofer enclosures, built-to-order boxes, vehicle-specific fabrication, CNC/laser parts, adapters, panels, amp racks, acrylic pieces, LED lighting pieces, Lit FX panels, and custom templates.
  • Special-order products, backordered products, vendor-direct orders, discontinued products, limited-availability products, and customer-requested parts.
  • Electrical items, wiring, cut wire, harnesses, integration modules, programmed items, batteries, lighting controllers, and installed accessories.
  • Products damaged by improper installation, abuse, overpowering, clipping, low voltage, water, heat, vibration, incorrect wiring, poor grounding, or vehicle problems.

Warranty Support

  • Products purchased through SMS are easier to verify, match, install, support, and warranty through the shop when the system was planned correctly.
  • Many product warranties are handled through the manufacturer and may require proof of purchase, serial number, photos, diagnosis, or manufacturer approval.
  • Some warranty concerns require inspection, testing, troubleshooting, or removal and reinstallation labor before the cause can be confirmed.
  • Product warranty does not automatically include removal, reinstallation, tuning, diagnosis, shipping, or labor unless SMS states otherwise in writing.
  • Warranty coverage may be denied or limited when failure is caused by incorrect wiring, low voltage, clipping, overpowering, water, heat, abuse, modification, or installation outside SMS standards.

Installation Labor, Tuning, and Custom Work

Labor is not the same as a product return. Installation, DSP tuning, fabrication, custom enclosure work, wiring, lighting, diagnosis, and appointment time are service work.

  • Installation labor, custom fabrication, DSP tuning, diagnosis, programming, troubleshooting, wiring repair, removal, and reinstallation labor are generally non-refundable once work has begun or been completed.
  • Custom work is built for a specific vehicle, product, finish, layout, or customer request and may not be returnable.
  • Changes requested after work begins may affect price, timeline, and final result.
  • Missed appointments, late changes, or delayed approvals can affect scheduling and deposits.

Customer-Supplied Equipment

SMS generally does not install products that were not purchased through SMS. This protects fitment, warranty support, tuning time, installation quality, and accountability.

  • Products purchased elsewhere may be missing parts, incorrect for the vehicle, counterfeit, damaged, incomplete, unsupported, or outside the intended system plan.
  • SMS cannot guarantee manufacturer warranty support on products not purchased through SMS.
  • If SMS makes a written exception, customer-supplied products may require inspection and additional labor for testing, troubleshooting, adapters, harnesses, wiring correction, tuning, or removal and reinstallation work.
  • SMS is not responsible for defects, missing parts, fitment problems, warranty denial, or performance issues caused by products supplied by the customer.

Batteries, Electrical, and High-Power Audio

Electrical planning matters. Amplifiers, batteries, alternators, wiring, fusing, grounding, and voltage support must be matched to the build. Product failure caused by low voltage, incorrect wiring, poor grounding, abuse, clipping, overpowering, unsafe installation, or vehicle electrical problems may not qualify for warranty support.

Battery and Electrical Upgrades

Before You Request a Return or Warranty Review

  • Order number or proof of purchase.
  • Product name, model, serial number, and photos.
  • Vehicle year, make, model, trim, and system details if installed.
  • Description of the issue and when it started.
  • Photos or video of wiring, fuses, batteries, amplifier settings, speaker wiring, enclosure, lighting controller, or installed product when helpful.
  • Whether SMS installed the product, another shop installed it, or it was self-installed.

Support Path

  1. Contact SMS first before shipping anything back or booking troubleshooting time.
  2. Send details including order information, photos, product model, serial number, vehicle details, and a clear description of the problem.
  3. Inspection or diagnosis may be required before the next step is known.
  4. Resolution path may include manufacturer warranty, repair, replacement, return approval, store credit, paid labor, or no coverage depending on the case.

Questions Before Buying?

If SMS is installing it, ask before checkout. The right product path is easier than fixing mismatched parts later.
