Works as intended
Size: 1-Female to 2-Male Y-Adapter-1 ft
What can I say? Works as intended. Seems pretty decent in quality and has a decent thickness to it! Fits pretty tightly so you don't have to worry about sloppy RCA connections.

Great Quality
Size: 2 Channel-3 ft, Size: 2 Channel-3 ft
Outstanding quality a very reasonable price. I was able to check the headunit RCA was showing almost 5 volts which was rated on the output of the headunit. I’m not an expert however i am assuming you don’t have to add so much gain. I’m very pleased and i will save this seller.
