My doors lock and unlock by themselves as I drive down road and I hear clicking sound too under staring wheel. I have very cheap alarm system in car already....

This could be the result of a couple things, a poor ground, poor power supply, body control module (BCM) or (and most likely) the aftermarket security system.

Now the problem, since there are hundreds of different manufacturers of these systems, I have no way to know how things are wired. I would start by removing the system and see if the problem is eliminated. If it wasn't, then I would start checking the items I mentioned.
