I've seen "pockets" and sliding drawers that supposedly fit in the space where a radio should go. Has anyone tried that? I hear it's rather hit or miss on whether these "universal" pockets work out on other vehicles.

Edit: I'm not looking for off-topic posts about what your audio setup is like or how you think my audio set up should be.
If your comment isn't addressing the question, kindly give this thread a miss. Thanks.
