Contract for in-ground 20'x40' signed on Monday. We're probably 3 to 4 weeks away from ground breaking. I've drawn up plans for pool placement, concrete, and fencing. We want to have music availble while we're outside. We dont have an inside system. So, I was wondering if there are any thoughts about pre-planning for speakers, placement of speakers, wiring (can do this before concrete is poured) and amps. Generally, we listen to XM radio and what we have downloaded from iTunes. Any ideas would be helpful!!! Thanks in Advance!!!
