We offer standard ground shipping (5-7 business days) and expedited shipping (2-3 business days) across the continental United States. Orders placed before 2 PM EST on business days typically ship the same day. Oversized enclosures may require freight shipping, and delivery times may vary. You will receive a tracking number via email once your order ships.

All Q-Power enclosures come with a 1-year limited manufacturer warranty covering defects in materials and workmanship. This includes structural integrity of the enclosure, carpet/finish quality, and terminal connections. The warranty does not cover damage from misuse, improper installation, water exposure, or exceeding the recommended power handling specifications. Please retain your proof of purchase for warranty claims.

We offer both vehicle-specific and universal-fit enclosures. Vehicle-specific boxes are designed with precise dimensions for particular makes, models, and year ranges — check the product listing for compatibility details. For universal boxes, compare the enclosure dimensions (listed on every product page) with the available space in your vehicle. If you are unsure, contact us with your vehicle information and we will help you find the right fit.

While our standard product line covers most popular vehicles and configurations, we understand that some installations require custom solutions. For custom enclosure inquiries, please contact us through this form with your specific requirements, including vehicle details, desired speaker size and configuration, enclosure type (sealed, ported, or bandpass), and any space constraints. Our team will review your request and provide a quote.
