Abbreviations used in the schedule. Clarifying categories

When looking at the schedule I see abbreviations such as FE+CS. What does this mean?
I know ehat SPL mean. I dont care to compete in SPL.
I am only interested in competing in the the Sound Quality portion. Is that allowed?

In the rules section of the web page, I see the Street Beat Division, Stock Division, and Trunk Division.
Where would I go to get a detailed description of these categories to help determine what category my car should be in, and the limitations of each category?

I am still using factory head unit and CD changer, I have replaced the factory amp with an after market.
I expect to replace the factory speakers with after market in the future, and just use the factory locations, nothing more.

Thank you in advance.

At the bottom of this page are links to detailed SQ points as well as an SQ score card.

The classes you listed are SPL classes.


FE stands for Full Event(SQ and SPL) and CS stands for Car Show.

Hope I helped.
