200-225 is prety unresonable if you want something that will last more then two weeks... expect about 500 to get bass wired up and in the car and thats for lower end stuff brand new, going used can save you some cash.
whats just the right amount of kick? i cant see strait and as far as im concerned i need 2000 MORE watts... so you'll have to be a little more specific on that one, like what do you listen to, and what are you honestly wanting this system to do? what are you looking for front to back? you have to be honest with these kind of things or you'll end up spending alot of money on crap that wont work for you and we dont want that! so take some time think of what you listen to the most and what you want from a system, and no we dont want you to tell us you want your bass to be heard from 4 blocks away.... although we can do that for you... its called acid dipped body panels
