i have a pioneer 22 rms x 4 ch cd player.. my car has cheap factory components in it.

i plan on getting the 30 rms 2 way pioneer speakers at walmart. coaxil.

should i leave the factory tweeter hooked up or disconnect it?

or should i get a cheap set of components? my 2 problems with components is i dont think i have enough power for them, and i dont want to risk buying a set that the tweeters wont fit perfect... and no i dont want an amp..

THANK YOU
