JL Audio Alternators

JL Audio was founded in 1975 by James Birch and Lucio Proni in Miramar, Florida, where they remain headquartered today. The company is renowned for engineering premium subwoofers, speakers, amplifiers, and marine audio systems with exceptional sound quality. Their W7 subwoofer is considered an industry benchmark, and innovations like the patented W-Cone technology and Stealthbox vehicle-specific enclosures have earned them a devoted audiophile following. Acquired by Garmin in 2021, JL Audio continues to set the standard for high-fidelity car and marine audio.
