Well, the guy I worked for at a car audio shop is part of team JBL... Mark Liggett is 2-time IASCA World Champ and he hooked me up... its just a partial sponsorship for now... Until I get my car completely built, then they are gonna review it then and either give me full sponsorship or nothing... they sound pretty nice from what ive heard, but I'm painting the amp right now to match the theme of my car... if you want some painted pics i can post them later today
