Default question about Sub pre-out

I'm about to install this in dash lcd screen and I notice the sub pre-out is just one mono black connector. How do I connect this to the amp RCA inputs (refer to pic below to see what I'm referring to)

Sub woofer is one channel not 2 therefore you only need one line. Just run a single RCA to your amp to either the left or right channel. The 1 RCA Sub out line is old school - in the past 10 years HUs started putting 2 Sub RCA outs on HUs to stop confusion since most mono-block amps are Left-Right RCA inputs - for whatever reason.

You can get a "Y" splitter for RCA cables and split the mono channel to the left and right channels.

LOL - I guess not anymore... Anyway, it never made sense to have 2 sub outs but like I said back in the day monoblock amps started going to 2 inputs and shortly after the HU makers followed. Either just run it to left or right on the amp or get a Y-splitter.
