Kick basses on the rear shelf

Evening people, I don’t know about kick basses, so my question: If I run the Rainbow SLX Deluxe in the front as a front system and install 4 kick basses with some tweeters in the back, what would that sound like???? Of course both systems at one end stage (Next q-24). Do I even need a sub or would the kick basses already provide powerful bass??? As I said, I don’t know about kick basses at all, so I don’t know how to pray properly. rubs and in which combination with front and sub you bring them together with it sounds too. What distinguishes kick basses from normal speakers or the sub? Thanks for your answers, already in advance!! Eddie
