This head unit has everything I want however it is only 2v out. My others have always been 5v or 4v. Should I be concerned about the 2v. I plan to use it with a JL 5 channel vxi.

from JL Audio's website, the VXi series RCA input voltage range is 200mV - 16V ... you will be fine with 2V preouts from the deck.
I am using a XD700/5v2 (200mV - 8V range) with 5V outputs from Kenwood DNX997XR and the gains for my tweeter channels are dialed all the way down to minimum, my mids are about 1/4 and the sub is under 1/2. I could switch to a 2V preout deck without fear of running out of room on the gains.
Hope that helps
I used to obsess about specs. Preamps had to be "this". Signal to noise had to be at least "that". I bought a Sony touchscreen head unit Christmas before last; I just picked out the one with the features I wanted and price I liked and went with it. It only has 2v outputs but it sounds fine.
Well let me just say this, I used to not look at signal to noise or preout voltage and had to buy new gear because my gains were so high i had a constant hiss at low volumes. So be careful. But... Crutchfield has a great return policy so it doesnt matter, try it out, if it is not enough voltage return it
The higher preamp voltage is there to minimize the effect of background noise. The goal is that if you pick up 200 mV of noise, if you have a 2V signal that's 10%, whereas if it's a 5V signal that's under 5%. Obviously that'd be a lot of noise, but the point remains, that you will then amplify that noise at your actual amplifier.
And if you do end up with noise than that is good to know, but way too much emphasis is put on something that MIGHT happen. People seem to conveniently forget that for typical listening levels you are likely putting out less than 1V on a deck that has 5V outputs. Sure the transients will stretch things out, but unless you are listening to Dragonforce at max volume all day long the voltage levels are constantly up and down. It's always been my understanding that higher voltage outputs are more about range of signal strength and less about interference.
If that's a misunderstanding then feel free to straighten me out.
