Car drives rough

When I replaced the front struts , the car drove OK. A few weeks later I replaced the rear shocks and now the car drives real rough unless on a highway. It feels like a mountain Jeeb. I feel like moving and bouncing in the car all the time while driving.
I know the new shocks and struts are not the best but despite the damage of two of the old struts,one on the front and one on the back, the car had been driving smoother than now with the new ones installed.
