scotty v

I recently blew out my stereo (amp in particular) by drawing the signal off of my back speakers...or so i am told. Anyhow, i have a nice 1.5 din alpine CDA-D855 in my basement from out of my GP. I was gonna redo my stereo correctly this time and i was wondering if anyone knows where i can get an install kit for a 1.5 din for our cars. also, would i be able to buy the adapter to continue to use the steering wheel controls for the alpine.
