Russell and Shannon,
First take a look at this page about pre-construction brackets.
As for the rest of the system, consider this, we generally like to see the theater area and whole house music areas on separate receivers. A surround version for the theater and a basic stereo receiver for the whole house stuff. Then, on the whole house audio systems, you’d want a speaker selector matched for the number of speakers you’d expect to have…like this one for higher power possibly: Audioplex MS8 and then volume controls like these: Audioplex VC200D
Hope that gets you started.
High power inwall speakers question from a customer:
I am building a new home and all the wiring for speakers is in the walls and ceilings. I need your help on selecting the speakers and volume controls. As Follows; (1) outdoor ceiling, (10) indoor ceiling, (2) inwall-3 1/2″ studs (6) volume controls. Home theater,(1) center,(2) front-1nwall, (2) back side-inwall, (1) ceiling-overhead. (6.1) I would like to put the mounting brackets in before the sheetrock in about three weeks. I have a budget of $3,000.00 (we like to crank the volume) Thanks Russell
