i'm currently building my new truck system. it's a 2003 GMC Sierra regular cab truck, planning to take out my first system (8years old), and installing my second system. the second systems consist of 2-kicker 12" L7's, Infinity Kappa 6 1/2", 4"x6", powered by Precision Power amps. well see how it goes.
by the way does anybody have pics of speaker box with 12" L7's. thanks
will post pic's later
