what would be my best rout to get rid of clipping with maximum output?

turn gain up on amp to desired level

or

use a crossover to boost my prevolts so i dont have to turn the gain up more.

i know they both turn your voltage output up....but which is better SQ wise?

Umm... to get rid of clipping, don't turn the gain up past your max input voltage. Noise is a completely different thing though. What are your current pre-out voltages? If they're over 2v, you will probably not notice a difference at all in noise when your gain is set correctly.

5v

but what im thinking is will 10v be better?

I think you have a fundamental misunderstanding of the relationship between the gain, preout voltage and clipping.

You won't get clipping from having too low of a preout voltage. If you properly set the gain, no clipping will occur. Doesn't matter if your preout voltage is .2V; properly set the gain and you will have zero clipping. Most amplifiers are designed to produce full power output with that low of a preamp input voltage...this is specifically what the gain is there for. To allow full power output over a wide range of input voltages without clipping.

Having a higher voltage preout does not reduce your chances of clipping.

What will substantially reduce your chances of clipping is properly setting the gain.

But increasing the voltage will do nothing about clipping if you properly set the gain in both instances.

im saying can i get louder with the same or no amount of clipping

5v vs 10v

what would get louder when gain is set properly in both setups?

Also; As Immacomputer mentioned....the only real possibility with higher voltage preamp outputs is decreased noise. But if you have no audible noise with your current voltage.....then increasing it will do absolutely nothing for you.

Neither.

With a properly set gain; they would output exactly the same power.

Again, this is exactly what the gain is on the amplifier for. To allow the amplifier to output full power without clipping over a wide range of input voltages.

thats what i needed to hear.

Here is a ghetto mspaint drawing of what is going on:

What that shows is exactly what squeak is saying. The final output signal will be the same for both pre-out levels but in the high voltage pre-out, you don't have to increase the gain as much to get that desired output signal. Anything above the red lines would be driving the amp past it's maximum output levels and would be clipped.

The amp is still doing the same amount of work but less noise is introduced into the system. A 5v pre-out is more than enough to keep noise low as long as your gain is set correctly.
