100W,200W CLass D amp for CAR audio

Dear All,
Consider me as a beginner in Class - D field & plz bear with my english. I had some projects on Car amplifier.

2.1 Channel Class-D CAR-AMP 100W/200W with Sub: 8ohms, Sat: 4ohms.
I know the basic opperation of Class - D amp but do not have any working experience with it all though I had working experience on Class - G,H & AB.

SO , any suggestion on component selection ( specially Class-D IC & switching FET ) , output LC filter designing , layout techniques will be helpful.
But do reply to this thread.
