Factory amp or not doesn't matter in this situation so just get that out of your head. Some amps have a high-level input on them meaning it will take wire connected directly from your rear speaker wire sets. Otherwise you'll have to use a line-out converter which you will have to splice into the rear speakers and that will turn that to a low-level RCA output. Be sure to turn the gains on the line-out converter to half so you don't distort the signal by clipping.

I'm actually an installer for Best Buy. You won't be taking anything from the back speakers whether you take the signal at the back of the deck or just before the harness from the rear speakers. There will not be a difference in sound. Line out is the way to go if there are no high level input options at the amp.

You have the high and low thing mixed up. A highlevel input will consist of a small plug with 4 pins in it that says high-level in. RCA's are low-level and require RCA connection from either the headunit or a line-out converter. Sounds like you don't have high-level in so your only option is the line out converter. You will still tap into the rear speaker wiring whether its behind the radio at the harness or back at each 6x9. It will do the same thing. At the rear speakers will be easier access if you don't want to take your radio out.

Either way you need to run speaker wires from the rear speakers for the high-level 8-pin plug or line out converter. High-level would be the way to go on this one cause your letting the amp convert which will result in easier setup and a little better sound with your factory deck.
