Your Opinions Please

I just ordered a set of black piaa 520 smr's and then changed my mind to get the chrome ones. i can return the black ones but i was wondering what other places could i put the black ones so where it wouldn't look tacky. I was thinkin the roof rack like a lot of other guys do but do you think the 520's are too big for an oem roof rack? any other places? all suggestions and opinions are greatly appreciated.

my vehicle is a black 04 dbl cab tacoma.
