Anything bad with 2V preouts?

I am looking for a deck and im just wondering about pre out voltage, obviously 4v would be better but would 2v still be good? even for something temporary?

i'm running 2.2 volts without any problem.

Just adjust your amp's gains accordingly, the lower the head unit's voltage output the more the amp has to compensate with it's gain, running dirtier.

Get a line driver for $50 and it'll be fine. I run a Kenwood DDX-6019 Double Din with 3 x 2v pre-outs..Awesome unit, I just run a nice AudioControl line driver.

Sending a nice hot signal to the amp allows the $100 line driver (Audiocontrol makes a little tank of a line driver) to take the abuse while saving your $1500 SAZ-4500D basically...

Who taught you about audio? You are wrong, wrong...and guess what.....wrong again. Please go learn what a gain on an amp does before touting wrong information to new people.

LOL Completely correct.

A higher input voltage allows you to lower the amp's gain. The higher than amp's gain has to be set (compensating for a low voltage input singnal) the higher the noise floor (DIRTY).

What's wrong about it?

This.

Preout voltage doesnt matter. Tune your amp properly and no issues.

yeah i definitely knew he wasnt right, just didnt mind the noobz on here. I just dont know too much about H/U's and needed some advice. thanks for all of it guys

A higher input voltage allows you to lower the amp's gain.

All the gain is is a potentiometer that allows you to match voltages.

The one thing that is an advantage is the higher the HU preouts voltage the less you turn the amps, which in turn lets the amp run cooler prolonging the life of the amp. However if its a quality piece of equipment it wont matter.

No nothing really wrong with it...still I do like my eclipse 8v pre outs

if pre out voltage doesnt matter then why is 4v better than 2v? just a stronger signal?

isnt that a misprint? i thought they had 6v...

Some have 8v, some have 16v balance outputs, some have 5v and a few are less.

well i think im just going to buy this WX-GT77UI | XplMd™ Double DIN CD Receiver | Sony | Sony Style USA and my amp will be my dtr.1 2200
