Subwoofer to headunit, single RCA?

[nstillmatic 10+ year member]

I'm looking for new RCAs to connect my subs amp to my headunit, and I can't help but notice that those labeled as "subwoofer cables" are just a single RCA. Is it logical to just connect with only one? I have a Pioneer AVH-P4200DVD and a Sundown SAX-1200D (mono), both have a left and right for subwoofer in/out -- so why should a subwoofer cable only have a single wire? Which is the best way to do it, just connect one cable from left to left or should I get a 2 channel one to use both?

a single rca cable should make a "Y" at each end...there should be two inputs on each end of the cable.

The subwoofer signal is a mono signal. The single connector subwoofer RCAs are meant for home audio.

x2 on the home audio, your input signal will not be as strong would be my guess, why not just run two like everyone else? Some of my older amps suggest only running one rca if bridged or mono or whatever, but from my experience, one rca will not be as loud.

run a single and y adapt it if you want to but its all the same in the end.

So its okay to run a single RCA cable and just use a Y connector, right? I'm having a problem with a set of my knuconceptz cables and this would be a cheaper fix.
