So I have been sittin here planning out my next system almost to a T, when the thought pops in my head, maybe I should find out the competition rules and types of competitions there are before I do any major planning. Does anyone have any ideas or sites I can hit up to find out the various competitions and rules regarding these comps?

My last plan was a F150 with shell on the bed. I was gonna do a wall with 4 18" BTLs, allowing the box to take up some room in the bed. I was probably gonna port front as well, but have some templates and planning to do first. Is there even a competition for such vehicle or do i need to go back to the drawing board.

4 18" BTL's

not sure of amps, but probably 3k watts to each sub, 2 amps

additional couple amps for comp sets up front and in suicide doors

at least 1 300 amp alt

big 3

couple extra batteries

probably some info on here
