When you split rca wires does the current get split too and the voltage remain the same?

Basically, yes. It creates a parallel circuit.

There are an additional couple of things. The source unit (thing the rca's come from) is designed for a certain range of load impedance (typically 10k ohms or greater. By Y'ing the RCA's into two 10k ohm loads (say, 2 amps), you lower the impedance the source unit sees to 5k ohm. If the output of the source unit isn't properly designed, it can increase distortion levels quite a bit and also effect the frequency response of the source unit.
