KING BOXES: Home of Top-Quality Carpeted and Bed-Liner-Sprayed Speaker Boxes

King Boxes launched in 2019, filling a need for speaker enclosures at a time when supply chain issues were hitting the 12-volt industry hard. Developed as a house brand for Audio King, a Marsden, AL retailer, King Boxes is keenly aware of retailer needs — especially the need to ship out top-quality product reliably and promptly.

King Boxes offers both black carpet and bed-liner-sprayed boxes. They also offer boxes that other manufacturers no longer offer as well as universal and vehicle-specific boxes.
