Hey dude, love the car you have looks friggen sick. You said earlier budget isn't an issue... Does that mean you wanna spend as little as possible or if you drop 3 grand as long as it sounds amazing you don't care? I sort of rushed into my purchase which was about 4 months ago and I regret purchasing so fast.
If money isn't an issue I'd research some more, look at some of the higher line rainbow comp sets, hertz sets, and if money really isn't an issue people can reccomend Dyn audio or morel products (don't know much about them), the last thing I would do is rush into a purchase for that nice of a car, you will really regret it even if you dont have you're system for that car show.
So if you havent purchased you're system yet a solid price range would help alot... If you already have then goodluck and I hope you like the sound of it. If you havent purchased yet feel free to Pm me, I'm not a pro but I've been researching a hell of alot the past 4 months and learned alot and could help you out with questions if you have them.
Goodluck!
