Go for the sound and brand you like.
Right, and make sure you get the correct size and ohm rating.

Impedance is the key. If you go wrong on that, it may damage the stereo. The impedance should be given for any speaker, usually on the packaging or printed on the rear of the speaker. Also, ensure that you hook up the wires correctly, there is a "hot" and "ground" just as with any electrical current.
