Looking for someone with experience in car audio?

im looking into purchasing a system for my extended cab 2002 silverado. i was looking online and im leaning towards the jl audio 12w7s because money is not an issue. if you disagree with my selection then dont be afraid to call me out on it because i have no experience in car audio what so ever. i am also wondering how i would set this up and hoping to get an idea of how much i would be spending. im open to suggestions, i just dont want any crap
