how do I test rca output?

I wanna check if my headunit is really putting out 5v. The reason is I had a 2 v output headunit before and I set my gains with a dmm and when I put this 5 v headunit I actually had to turn my gains up instead of down to get the ac voltage I needed wich was 15.
I used the same test tone and same dmm
does it sound bad? unless you have a performance issue I wouldnt worry about it. 2vac is plenty signal to get good and loud and still have good SQ. higher voltage outputs will allow you to turn your gains down, but unless you are having a noise floor issues, kinda pointless.
