King Boxes Subwoofer Enclosures

Press Release: EDMOND, OK– Petra Industries, the consumer technology authority and electronics distributor, is excited to announced the addition of King Boxes to its 12 volt family of products.

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. Initially developed as a house brand for Audio King, a Gadsden, AL retailer and now spun off as its own entity, King Boxes understands the need to not only produce top-quality product but to also ship orders out quickly. Their portfolio includes a variety of enclosures, from black carpeted boxes, to bed-liner sprayed boxes, alongside offerings that fill gaps left by other manufacturers, including both universal and vehicle-specific boxes.


“We chose King Boxes for their high-quality speaker and subwoofer enclosures and their ready availability,” said Tate Morgan, President, Petra Industries. “Not only does the brand enable us to offer a larger assortment to customers, but also their inventory supply is consistent and their prices competitive. Anyone in the 12-volt space looking for quality speaker enclosures certainly needs to spec our assortment of King Boxes.”
