Hey Jai, everyone has already told you you don't need to do anything with the empegs output voltage! Don't you listen????

The empeg will only output 4V if you turn the volume right up. If you leave the empeg volume turned down a bit (you are going to be using your other head units volume as the mail volume control anyway aren't you) then you aren't going to have any problems! Actually I think someone even had a software hack that disabled the volume control on the empeg! You are going to have to search a bit to find that message on the BBS though ...
