No JTAG or RGH hacking is required for this very fun mod, you can either use one of the current stock sounds that are included in the Limited Edition consoles (GOW3, MW3, Star Wars and Halo Reach) or use one of your own customs sounds! The Sonus 360 QSB Kit is easy to solder to your Trinity or Corona board and you simply hook it up to your JR Programmer and program which sounds you required using the Sonus 360 Sound Editor.
Note: An Xecuter JR Programmer is required to program the sounds to the Xbox 360 Slim and the Xecuter Sonus 360 Speaker Upgrade Kit is required for Xbox 360's that are none Limited Edition versions (GOW3, MW3, Star Wars and Halo Reach editions all have a speaker included. All others have a cheap low quality buzzer type speaker and they will all require the Xecuter Sonus 360 Speaker Upgrade Kit)
