Factory Delco CD player question

Do the Delco factory CD players in the '99 GTP's have RCA jacks on the back? I want to install an amp and 2 10" speakers, cause I'm getting an extremely good deal on them, but I don't have the cash for an aftermarket CD player right now.

There are no RCA jacks on the back of these radios. If you want to add an amp to your existing radio, you'll need a line-level converter to reduce the signal from your speaker wires going into the amp. Some amps come with these already built-in. So, depending on the model you choose, you may or may not need the separate converter (looks like a big resistor - not very expensive).
