My e24 speakers sound like they are on their way out, so it's time to replace em. Not looking to spend too much but want the best bang for my buck. Keep in mind that I don't have a sub or amp (and don't plan on putting one in) so something that would sound nice being run off the headunit would be nice.

My headunit is a Kenwood KDC-255U, speaker sizes are 4in and 5 1/4in.

Any advice on what to look for?
