Your questions answered.

Every vehicle and goal set is different. Start with our sound deadening buyer’s guide to understand what each material does and where to use it. If you want a tailored plan, book our sound system design and installation consultation.


To help offset the cost, up to 40% of the consultation fee can be credited toward ResoNix product purchases made within 30 days.

Most people ask this because they are not sure what physically fits. Fitment varies by vehicle, trim, and where you plan to install it. Check available depth carefully and avoid interfering with moving parts, window tracks, airbags, and service access. As a general rule, choose the thickest that comfortably fits the space. See the product page for details.

We are building an ongoing fitment sheet from customer confirmations. If you can share what fit in your vehicle, please let us know to help others.

If an item is on backorder, the estimated restock date appears on its product page and is updated as we get new information.

Domestic orders that include a backordered item will ship in two parts: in‑stock items ship immediately, and the backordered items ship as soon as they arrive. For international orders, we currently ship when all items are in stock.

You will receive an order confirmation by email, then a tracking email once your order ships. If you need an update or anything looks off contact us with your order number.

We recommend high‑quality, proven DSPs matched to your system design and goals. If you want a custom recommendation, book our sound system design and installation consultation.

To help offset the cost, up to 40% of the consultation fee can be credited toward ResoNix product purchases made within 30 days.

Yes. Start with the sound deadening buyer’s guide for material selection and placement, and the sound deadening reference information & guide for deeper technical detail and best practices.

Please open every box and wrapper fully, since small items are sometimes packed inside larger kits for protection. If something still appears missing, reach out with your order number and what you are not seeing.
We will make it right. Contact us.

Yes, we ship worldwide. Available carrier options and rates are shown at checkout based on destination and weight. Transit times depend on the service you choose and customs processing. Express options are typically faster, while economy services take longer.

Full details are here: Returns and refunds policy.

If you need to cancel an order before it ships, contact us as soon as possible. If a return is needed, follow the instructions on that page so we can process it quickly.
