My school has asked me to install a new audio system in the gymnasium. What information do I need to do the install properly, what equipment is recomended.Thanks,

Follow Ups:
I now feel very dumb, I am a senior in high-school and spent this past summer working for a commercial sound installation company. I did a number of jobs installing systems in auditoriums, churches, and other large rooms.I will repost my question in the coming weeks when I get a better idea from the administration of budget and necessary equipment; and yes I will bring dimensions.
Thanks,

Unfortunately a large percentage of commercial sound system installation companies don't have professionally trained audio/acoustical engineers on staff who know how to design a system that actually sounds good. If the customer is MacDonalds or the like and all that's desired is background music it matters little, but if fidelity is the goal then just slapping up some speakers and running some wire is not going to do. The largest part of the job is often acoustic correction, especially in gymnasiums and other large public rooms, most of which should be right at the top of the list of how not to build a room for good sound reproduction. Second on that list is the average nightclub. Ask any roadie.
Your knowledge is always soothing, any sources for me to read about acoustic correction for gymnasiums and the like.

If you don't do an acoustical analysis of the room and your design, expect the possibility of having a lot of trial and error.

I'd head over to the tweaks section and see if anyone there has advise on that. Perhaps Jon Risch. He's really into basstraps and such.
Because of all the variables involved and your seeming to not
have knowledge to do this without help you might want to get
a pro to come on site to make recomendations
Question 1 – What is the Budget?
Question 2 – How large is the gym … is it small with 1 basketball court and bleachers or is it massive with multiple courts and a track?
Question 3 – Is it a permanent installation or is it something that has to be stored when not in use?
Question 4 – What will be the primary application? Will it be used for announcements, etc., or will you need it to put on musical production (e.g., school band, battle of the bands, etc.)For example, if it is a small gym, you are on a budget and the system has to be stored between uses you could get by (these are only examples) with 2 Peavey cabinets with a 15 and a horn in each, the poles to support them, a QSC stereo amp at 200W per, a 4 channel Mackie mixing board (actually, 4 XLR inputs), 2 Shure SM58 microphones and the associated cables and mic stands, speaker cables and other assorted cables and power lines and maybe a DJ type CD player for good measure. For a system like this you are looking at less than 2 grand.
A system like this will serve you well for announcements (and maybe playing some background music if you buy a CD player) and it will allow you some flexibility if you find you need to expand the system for other applications.
Rutgers has a great permanent installation in one of their weight lifting rooms. The room is block, mirror and hard wood with very high ceilings. The cabinets (multiple) are mounted from the truss work in the ceiling via chain facing down and the system is used for music. Surprisingly, it sounds really good.

If it's a typical gym you should spend 25% of your budget on gear and the rest on acoustical improvements lest the investment in gear be a totally wasted expenditure. Even the best gear won't sound good in an echo ridden environment.
