Need help finding the right resistor.

I’m new to wiring and I need help to find the right resistor for my project. I’ll be having motion sensor LED strips with a power supply of 12v volts and 2 amps. The LED strip, which I’ll cut into 4 separate strips, need a power supply of 12 volts and from what I’ve seen I need a resistor of 1k ohm for a single LED strip but I don’t know if I’ll need a different resistor for a single cable splitting to power 4 separate LED strips. Also is it safe for a power cable to split 4 way with a single resistor or shall I need each LED strip to have a individual resistor.
