Here's an area that some people don't understand. "Why would someone want to spend thousands
of dollars for a stereo system in their car??" they might say. My answer is - "I don't know!" But it was one of my favorite hobbies, especially the summer after I bought my Executive. At that time I became involved firsthand in the world of competition car stereos. Although I only competed in the finals of one local stereo contest, I think it gave me a good intro to the sport and an appreciated for the time and equipment that many drivers invest in their cars.
Here's a diagram of the setup that was in my Pontiac for that season...
Along with the equipment shown, I had all the other electrical goodies (a StreetWires 1.0-farad capacitor, gold plated battery terminal, power distribution block, fuse block, and capacitor eyelets).
And I've gotta give props to the Alpine head unit & amplifiers and the JBL
speakers and subwoofers that made up this system. Check out their homepages below.
