When connecting a subwoofer, e.g. to a home theatre system, there are usually one or more outputs for active subwoofers. Sub-outputs are usually only 1 Phono RCA connector, as the signal is mono, also called the LFE channel, which makes up X. 1 in the naming of a 5.1 or 7.1 surround setup.
Can I use RCA output for subwoofer?
In order to hook up a powered subwoofer properly, an RCA "splitter" cable ("Y" cable) is not needed. Any single, standard RCA or subwoofer cable should do just fine. However, if the sub is exhibiting a hum with the RCA/sub cable plugged into it, then maybe try using a "shielded" subwoofer cable.

Why do subwoofers have 2 RCA inputs?
Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. If you have a processor with very low output so you can use a Y-splitter. By using both inputs with the same mono signal doubles the subwoofer sensitivity.
Does subwoofer use RCA input?
