Meet the President & CEO

Julio Diaz (JC) began in this field as a helper in a local store in his hometown. He would put in a few hours after school as he learned about the business. Before starting his own corporation in 2000, JC worked in the industry of car stereos and alarms for 12 years. Now with more than two decades of experience and an electrical engineering background, he has earned great respect from many and become well-known on Long Island for his perfectionism, quality, and creativity.

JC established his own company and has continued to gain reputation as being an innovative leader in the car audio and accessory industry. In February 2015, he was named an International Entrepreneur by the International Leadership Team. JC also works alongside his brother in the distribution industry as the sole distributors of Beyma™ speakers in the Caribbean and the US. They are business partners with the owner of Carbon Amps, a partnership which is exclusive to Intense Kustom Audio.
