A high-to-low level converter. I suggest you use a PAC unit, but your amp probably has high-level inputs as well. You would t-tap the lines going to your door speakers, usually the rear set (most people fade to the rear in stock form). If you've got the factory amp, you t-tap off it's outputs.

There is no right way. I did hook up my RCA's to the wires that go to the factory sub. It worked for me untill I ripped all of it out. I don't recomend doing this. 
Come on CH I know you have something to say about this.

Tokyo nailed it, that's the best way. 
Even though the mono amp I am going to use to drive my sub has high level inputs I am still using a line level converter. To my knowledge using the high level inputs on the amp can lead to more clipping as opposed to using the RCAs. I could be wrong but that's what I gather.

I used rca's and tapped into the speaker wires between the deck and stock amp. I have not had any problems.
I have the premium sound and didn't use the line converter because the wiring diagram says they are low level inputs.
