D&R Intimidator Siren (O.P.P Police Version) 1.0.0

Warning 
There are reports that certain audio archives have been muted in game regardless of rather the sound mods were installed properly or not. To ensure that the audio archives for vehicles won't be muted in game make sure that the vehicle.oac file or the vehicle.awc file doesn't exceed over 15.75 MB in size (you can check the size of the vehicle.awc file in OpenIV under RESIDENT.rpf) and make sure that the siren sound audio files have the appropriate bitrate/sample-rate/etc (32000hz, 16bit mono, 512kbps) for the vehicles.awc file. 
Hopefully this will resolve the issues regarding muted sirens in game. If not then please let me know so I can farther troubleshoot this. Other than that, please enjoy this siren sound mod! 
 

Note: The original Ontario Provincial Police (old) D&R Intimidator siren mod for GTA 4 belongs to Laikmuay. However I did some very minor edits and tweaks for the siren sound mod to work in GTA 5. So all credit goes to him.

This is a D&R Intimidator siren sound mod to replace the main police sirens in the game.
