hey had a question to a those that might have a clue

I'm going to start working more on my interior and want to put a large monitor in the trunk area I'm going ot use a 19" inch LCD computer monitor (maybe two...haven't decided yet ) I'm trying to figure out how to have the "float" in the back do I install them to the back of the rear seat back or maybe get a rear strut bar and do somehting with that? Let me know what you guys think and also instructions/pics if you have them!
