Review on 15ft Mediabridge Ultra Series RCA Y-Adapter - 1-Male to 2-Male | Digital Audio & Subwoofer | Dual Shielded, Gold-Plated RCA to RCA Connectors | Black (CYA-1M2M-15B) by Joshua Carter

Quality feeling, working cables. I used this cable to connect a powered subwoofer with 2 RCA inputs (red and white) to my AVR (receiver) with 1 RCA subwoofer output - they work. One thing to note - the clamps on the jacks are SUPER tight so these plugs have to be FORCED into the jack and if what you have them plugged into is relatively cheap like my subwoofers then pulling those will pull Also unplug the RCA connector. RCA plugs from these connectors and plug them back into my subwoofers. Just remember that wherever you plug them in, they can stay there for life.
