Car stereo gurus, I need your help

I'm wanting to install an amp and sub in my new raptor, but want to keep the factory head unit. I've always installed an aftermarket head unit in all of my vehicles, so I'm not caught up with the current rca converter technology. What converters are good and out there for wiring 2 pre-amp outputs with a sub output. Thanks in advance!

Check these out. The guys I knew that used to do this used them and they seemed to work out pretty good.
