Thanks for all the help guys & gals!
I took car to dealer today and had the guy dry/clean/detail the interior. Engine and computer should be fine - the car's been running fine since I realized it was flooded. It wasn't too much water, just about 3/4" on the passenger's side.
Sub seems to be either shot or very angry with me. We'll see what happens in a few days, but I'll keep you in mind, Dredd. Thanks!
I haven't pulled up the carpet, but will put car in garage and put fans on it overnight and see where I'm at.
I don't expect to see the sun here for several days, so that's not an option.
Thanks for all the help - for everyone in Charley/Bonnie's path - stay high and dry!
