05 Malibu LS, Not MAXX Stereo

Hi, im interested in adding perhaps a subwoofer/amps to my vehicle. Now i have been told from a few sources that newer cars from around 03 and beyond out output plugs in the back of the stereo. Im wondering if anyone know of such in my vehicle.

I don't think so, I have 06 Malibu. I just take the stock out and put the Kenwood with MP3/USB in. I am lazy to switch the CD disks, I use the 2 GIG USB stick and store hundreds of songs, it's wonderful
