Installation:

1. In OpenIV, go to pc/audio/sfx/resident.rpf/RESIDENT
2. Enter in Edit Mode, and drop the WEAPONS and EXPLOSIONS in there

Optionals:
In Optionals, you've got 1 file.
SOUNDS.DAT15, which contains edited tails for most guns, giving it a more louder volume. However, this file is incompatible with mods such as The Actual Complete Edition and Revamped Combat, and Radio Downgrader
I'm working on an addon sounds.dat15 to fix this, but for while, you can manually edit the files via a tutorial i have on GTAForums: https://gtaforums.com/topic/995647-ivtut-louder-tail-sounds-via-rageat/

To install this, just drop it in pc/audio/config and replace
