Editing Battleground/Arena Que Pop Sound

[dealerx]

Hello, i want to create a small custom MPQ patch, I want to modify the sound when the arena/bg que pops up with a .wav created by me, I've opened all MPQ in the data and data/enGB folders but i cant really find that sound, but there are too many folders and files to look for.

So:
1st): Where exactly is located the .wav file? In witch patch?
2nd): I could simply modifiy the original MPQ yea, but is it possible to just create a new MPQ like "Patch-S.MPQ" with only that sound added or it creates "conflict" with the original MPQ?

Thanks for the help! =)

EDIT: After some research i FINALLY found where the fils is:

Common.MPQ>Sound>Spells>PVPThroughQueue.wav

Hope this will help someone!
