I don't really know if this is the right topic. actually i don't even know if this is the correct word. my problem is: i am renting a garage with a group of friends and the idea is to play in it. we have to make it really well because no noise can get out of it, we don't have much money and we would like a nice sound even if it's small (6m X 2.50m) i know we are asking too much but this garage is perfect because of its position and we would have to wait years to find a better one. any suggestions? i haven't done anything similar before, so i'm a little confused... thanks!
