Construction Question

Ralphnoonan, you have to forgive us for out zeal in trying to help you put together a truly quality home theater project!
We here at A'gon (and I think I speak for many here), simply are interested in not only ourselves, but people like you who are DIY'ers (if Novices) getting excellent results from your project. Many of us know that, without some expert guidance, your system will go the route of the vast majority - mediocre-ville! And we simply don't want that for you, in our selfishness. So for that, please for give us.
Back to your question:

"Does anyone know where a person could get some info or plans on the net?"

Yes, simply go to www.google.com, type in "home theater construction techniques, and pull up a near endless supply or information pertaining to your topic!!!
You will then have about as much varying opinions, suggestions, bias's, differing design ideas, construction techniques, varying views on room dimension recommendations, structural design parameters, and as many opposing view points, as you will get by asking everyone here on this site, which equipment you should chose!!!
Sorry, but I simply don't see how getting someone to point some site where you might find "one person's" recommended building plans for your job, where you can actually decipher whether they would be what you would want to chose for your project!!!
But, that's just me...
Good luck

Thanks for the responses.I own a painting company and met a local,on a far away job.He was the installer of all the inwall,theater,nuvo,and security.He's going to come over and show me some tricks,and how to wire everything for free!..Thanks again for all the posts.

Lol! You've got to be kidding. You made it clear you wanted no outside assistance, and yet that's exactly what you did! Go figure.
Did you even know what you wanted? I think you just wanted attention.
Regardless, I hope it was everything "someone else" wanted it to be, and less!...lol
