I didnt get it I was thinking about getting it from a friend, thats why i made the post cause i wanted to know how to hook it up and if it was worth trying myself

 

It's a decent amount of work..and as previously mentioned virtually pointless if you plan on using the stock deck...not to mention you'll need an amp and whatnot.

And I'm not trying to discourage you lol...you're young (I still am too, so I can't really speak like I'm that much older and wiser) and to have a sweet ride like that at your age...I would have loved it.
Just try to be more educated in your posting..that's all. You can do a lot of the research yourself...google is a great tool that would give you a basic overview of hooking up a sub and amp...and that doesn't mean I'm saying not to post questions here..because I'm happy to answer what I can...just don't get all worked up over nothing.

 

And thanks for the help dude, see my friend drive a BMW and right now he has two kicker twelves pushing 1200 watts total, he has his old 10 inch and box and amp he was gonna sell me for 65 bucks, its nothing special but its bass lol, i might just pick it up for future use
