Review on ⚡️ iExcell 2 Pcs RCA Speaker Splitter Shielding Cable Adapter - Efficient Blue Design by Gregory Castellanos

Decently made but poorly designed. The device is used to separate the stereo signal. The problem is that the master connector goes to the output and then branches off to RL. Obviously the signal from an output is either right or left, so you'd need to cross-connect extension leads to get a stereo signal. No instructions. My stereophile test showed this on the position track, with the same tones coming out of the left and right speakers.
