Yes, of course you can. Go into Best Buy or whatever, tell them you need the plug n' play wiring kit for your car and specify that it has a pre-amp system. What they should bring to you is a set with 2 harnesses - first one is the main harness and has several wires, second one is a square plug that only has like 2 or 4 wires (check the back of your stock head unit, you'll see what I'm talking about). Costs about $20. You'll also want the install kit bezel; regardless of if you go with a single or double-DIN size unit you will need it.
