Memphis is a long-standing American car audio company known for building high-output speakers, amplifiers, and subwoofers. The brand was founded in 1965 and has spent decades in the 12-volt industry developing aftermarket audio solutions for cars, trucks, marine, and powersports vehicles. Its operations and distribution roots are tied to Memphis, Tennessee, with corporate facilities now based in Olive Branch, Mississippi.

Memphis specializes in a full range of mobile audio equipment, including component and coaxial speakers, high-power amplifiers, subwoofers, bass enclosures, and digital signal processing solutions. The company is especially well known for its subwoofer and amplifier lines—like the MOJO and Power Reference series—built to deliver strong output, durability, and deep bass performance. Many of their products are designed and developed in the United States and engineered for both everyday listening systems and high-energy SPL builds.

Memphis has always centered its brand around loud, impactful sound paired with real-world reliability.
