Will my old house stereo speakers work with new reciever?

I have a 15 year old Fisher house stereo that still sounds brand new, its got 2 speaker towers with 1 15" sub a 5" tweet and 3" tweet in each tower, thing is the receiver in the stereo works great pushing 240 Watts, but the 24 disc CD carousel doesn't and hasn't worked right for years, and the the model only has 1 input with RCA jacks on the back, if I got a new receiver that they call home theaters now would it run the speakers properly cause each speaker tower has only 1 wire hookup but its old school without rca's just wire, and I want a receiver I can run all kinds of components through, thankyou
