First of all, it's stupid the way Chevy wired everything in the car to be controlled by the stock radio. Yea, technically if you want an aftermarket headunit in the Malibu, you gotta connect the stock radio. In fact, the wiring harness kits for the Mali include an extra cable where you can do that.

I said "technically" because the guy who did my headunit was able to wire it in a way where I didn't need the stock radio. I'm sure if you take your car in somewhere, they'll wire it this way too.

As for the installation kit, drop by a local car audio place. I didn't have any trouble finding an installation kit for my car (which is a 2001).
