Answers about ordering, payment, shipping, custom boxes and choosing the right enclosure.
Orders and payment
How do I pay for an order?
Choose wire transfer, Zelle, Apple Cash or Cash App at checkout. Your order is placed on hold. Reply to your order confirmation email when you are ready to pay and our team sends you our official invoice and the payment details. See the payment policy.
Do you take credit cards?
Not online at this time. We accept wire transfer, Zelle, Apple Cash and Cash App.
When does my order ship?
After payment has cleared. We confirm the carrier, cost and delivery estimate with you before it ships.
How much is shipping?
It depends on the size of the order and where it is going. Checkout shows shipping as cost confirmed before it ships, and we agree the cost with you first. See the shipping policy.
Custom boxes
What do you need for a custom box quote?
Your vehicle (year, make, model), where the box goes, your subwoofer model and how many, and sealed or ported if you have a preference. Measurements of the space help. The custom order form asks for all of it in three steps.
I don’t have subwoofers yet. Can you recommend some?
Yes. Choose “Recommend subwoofers for me” in the custom order form and tell us how you listen. We suggest a sub and box that fit your space.
Can I return a custom box?
A custom box is built for your sub and your vehicle, so it cannot be returned once the build has started. If there is a problem with it, contact us. See returns and refunds.
Do you ship custom boxes?
Yes, anywhere in the United States. Larger boxes may ship by freight.
Choosing a box
Sealed or ported?
Sealed boxes are smaller and tighter, and work well in most daily drivers and trucks. Ported boxes play louder for the same power around their tuning frequency but need more space. Our sealed vs ported guide goes deeper.
How do I know a ready-made box fits my sub?
Compare the box’s net volume with the volume range on your subwoofer’s spec sheet, and check that your sub’s mounting depth is under the box’s limit. Every enclosure listing shows these numbers where they are published. Or send us the model and we will check it.
What is net volume?
The air space inside the box after the wood, the subwoofer, the port and any bracing are taken out. It is the number to compare with your sub’s recommendation. Try the box volume calculator.
Will a box fit behind the seat of my truck?
Often, with the right driver. Space behind the seat is usually shallow, so shallow-mount subwoofers and vehicle-specific boxes are common. Read the truck sub box guide and send us your cab type.
