What kind, and how much of a difference would i notice with 2v , 5v, or 8v preouts??

I will let you know tommorow when I go from 2v in a Pioneer to the CD5000 8volt.

that would be perfect if you could....i was actually lookin at picking up the CD8445...eclipse with 8v preout 55ohm resistance.

if you have your gains set per the gain setting manual, see how your gain settings change with the new headunit

i'd be interested to see

I'm see how it is now and then set them gains to JLs accordance numbers (prob end up bumpin them down 6v) and I'll let you know.

I doubt that there is No difference. the difference in SOUND is very noticeable going from 2V to 5V.

Completely false.

There is no difference in sound.

Just like it says, what kind and how much of a difference would I notice going from 2v to 5v to 8v preouts??

Assuming there is no audible noise with the 2V setup, then you will hear zero difference.

I have "heard" that with a higher preout voltage that the amp wouldnt have to work as hard, and that I would get a stronger and cleaner signal which would make it louder. Is there any truth behind what I've "heard"?

Not true.

when i switched from 5v to 8v preouts..my bass was noticably louder....i mean alot.

Then you didn't reset the gain correctly (if at all)

So it is easier on your amp then, b/c then you dont have to turn your gains up as high?

The only difference would be if your amplifier had audible noise with a higher gain setting.

If it doesn't, then you will hear no difference and there is no difference in performance in your amplifier.

lol I was waiting for squeak to chime in.

well....the727kid let us know what you find out.

Bump to the top......what kind of difference are we looking at guys with different preout voltages?? It seems different people have different opinions, what are the facts here??

The fact is that the only potential difference is an increase in the signal to noise ratio when going with a higher preout voltage. And, therefore, if you had no audible noise with a lower voltage...going higher is going to gain you nothing.

I think his question is "Does gain level cause the amplifier to work harder/harder on the amp/ etc"

No.

Alpine of course has the 2v preouts...so would it be smart of me to sell that headunit and get one with a 5v or 8v preout, or should I just leave it since it sounds pretty clean to me right now?

Do NOT change simply for preout voltage.

If you want to change, change for something worthwhile...such as "because the new deck has better crossover selection, more equalizer bands, etc"

Will the sound be a lot cleaner if i was to go with an 8v preout HU ?

Not if you have no audible noise right now.

So really theres nothing wrong with low voltage preouts as long as its a clean signal? Am i following this correctly?

Yes.

Some of the most highly respected "SQ" decks don't offer voltages over 2V...some have even been as low as 1V.

If your only reason to switch is the input voltage, then yes, stick with what you have.
