 Hi first you need an audio editor software for gta vice city like GTA 3 AUDIO Editor the link is here:

Then after download you extract the gta 3 audio editor to a location on your computer, 
you enter  in the audio editor and on File you select the game location to the audio files of gta vice city ,and then click sfx.std and a huge audio files list opens and you just need to replace the 
game files with my mod audio files you just need to find the exact name of the audio files
 from game and you just replace with my mod files the software rebuilds the archives itself then you can close the programm.
