Query: What i wanted, but doesn't fit my radio

I got this for my "Boss 612UA MP3-Compatible Digital Media AM/FM Receiver" which i also got on Amazon. And after my friend and i spent an hour and a half figuring how to take my car apart to get the radio out in 30 degree weather, we went to attach the radio to this installation housing, and it didn't fit. so then we had to put my car back together and im still trying to find a housing that fits the radio. i found this all very annoying and frustrating because on the box for the radio it specifies what size of this to get and this is the one i chose and it doesnt fit! i wasn't sure weather i should write a bad review for this or the radio and i decided on this because i havent used the radio yet so i dont know how well it works and the box said to get this size so thats what i did... and it didn't fit.
