The car acted like it was slower to start for 2 days and the second day the parked car after driving for an hour came out and wouldn't start. I replaced the battery, starter, and starter relay. Now the car just rapidly clicks in fuse box and at starter and dash lights flicker with clicks. Please help, thank you.

This sounds like a bad ground or positive battery cable. It could be a bad ignition switch as well. I would check the cable connection to make sure they are not loose or corroded.

This sounds like low voltage, is the battery new? This guide can help test it without testing equipment:
