Finally getting to the stereo system in my car. 72 rr GTX with factory rear defrost. I'm keeping the original look by leaving AM radio in the dash and installing a hideaway system. Front 4x10 is no problem, however, the rear is the issue. Whatever speakers there were have long since been removed. I saw an earlier thread here discussing this topic, but there isnt much detail. I'd like to install either 2 6x9s or 2 5x7s under the rear package tray. Right now the defrost blower is mounted in the passenger side speaker area. I have found blower & speaker housings for 70-74 E-bodies allowing you to mount the blower motor and speaker side by side, but nothing for B-bodies. I'm not sure if this housing would work for my car. Has anyone solved this issue? If so, how? Any input would be greatly appreciated!

I thought about the same thing a coupla' years ago, It seems that when I tried to install the adapter housing the trunk lid torsion bars interfered. Just what I remember, could be wrong though! Try it and let us know!

Wayyyyyyyyyyyyy back in the day, when I used to actually drive these cars every day, year 'round, I had stereo speakers and rear defog. I lived in the snow belt and NEEDED the thing!

Anywhoo, I used to mount the blower motor to the crossbrace behind the rear seat. Probably didn't suck in as much warm interior air as the speaker hole, but it worked.
