Help with headunit installation

I just bought an alpine cda-9807 head unit and want to get it put in. The only problem is I have no idea what I'm doing when it comes to electronics and don't want to pay a ton for circuit city to put it in. Anyone in the austin area wanna give me a hand, I'll pay $30 and lunch for something.

If you free tommorow I can install it for you or on wednesday. I live upo north. You can buy pizza from Austin pizza and we will call it even. Call me at 653-5364
