I had to pull over in a parking lot, remove the bumper and drive back with it in my backseat.

Also, to the original poster's question. I don't think you should just upgrade the head unit. A bigger head unit should be combined with more intercooling or water/meth inj. or something. How much power are you wanting to make? The bigger head units + more cooling of intake charge will equal more power, generally speaking.
