As noted ^^^ above it is ALL THERE in a plethora of threads. Search function is your friend. Enough content for you to read all night, into the morning and the entire morning. Put on a pot of coffee and indulge. Oh might want to make sure that your printer is full of toner and that you have an entire back up of toner.Welcome!
Many excellent threads here on DIY sound systems. Had a shop do mine, but worth it to me.
Good luck with your install.
