preamp voltage???

i'm upgrading my jensen uv8 to the vm9512 tomorrow....and i noticed that the 9512 has a higher preamp voltage....what will the higher preamp voltage cause?

it will let the amp work more effiecent and you may get a little clearer sound out of the speakers. You will be able to set the gains lower and the amps won't have to work so hard which is a good thing

well that's nice to know....because my setup is 2ohms bridged across a stereo amp...which splits across each channel, dropping it to 1ohm....and with my amp being 2ohm stable it handles it pretty well, although it tends to get a little hot.....so maybe my amp won't get so hot, therefore it may last longer..(unlike my p.acoustik amps)..lol

how is it not true? Higher pre out voltage on the HU makes it easier on the amp.

the amp will be "working" just as hard.....the gains will NEED to be set lower. Higher pre-amp voltage only lowers the noise floor

OP - A higher preamp voltage will NOT keep your amp safer.

If you are running a 2 ohm stable amp down to 1 ohms, it is only a matter of time before it goes poof.

I would suggest finding a way to keep the amp in a safe load. Upgrading preamp volts will not make the amp work less hard.

A higher voltage is supposed to send a cleaner signal to the amp, it "allows" you to keep gains in the HU lower thus having less distortion in the signal

so let me see if i'm getting this right your running your amp at one ohm, using 2 ohms speakers? but yet your amp is only stable to 2 ohms? if your amp isn't one ohm stable it won't be long before your amp goes bad. with the deck putting out more voltage won't help the fact that your running your amp at an unstable ohmage. King was right in saying that the gains may need to be turned down. but i'd be more worried about running the amp at one ohms when it's only 2 ohm stable.

yes, if you have two ohm speakers, you will need a 1 ohm stable amp.
