fender speaker

Speaker system in trunk, customization for a 1996 New Yorker, fenders? Hoods? Anything else? HELP please?
I want to customize this car to it’s fullest extent without paying so much, It’s always been a dream to take something like a New Yorker and make it something more than just… what it started as. I’m planning on putting a full speaker system in the trunk and I’ve got all that planned out so far but what do you think I should do with it? Is there any fenders or skirts for it or hoods or anything? I’m pretty in the dark this is my first shot at it so need some help, thanks so much.
Skirts for a New Yorker, not sure about that, check cardomain.com for pics of other owners’ cars
