HU qualities...voltage or S/N?

[southwest713 10+ year member]

which would be more important?

to have a better signal-to-noise ratio or to have a higher voltage pre-out?

for example a pioneer HU with 5 volt pre-outs vs alpine with 2 volts but better signal to noise ratio?

Neither are really anything to base your selection on...but out of the two, I'd say that S/N is one you can ignore.

Once you get over the S/N of the format, it won't make a shred of difference...

oh, i was just wondering cuz the guy from alpine at the dub car show was talking about nothing else mattered and how alpine was better than pioneer because of the s/n. i know he was biased but it made me wonder how important that really was.

The Alpine may have different crossovers or ergonomics that better suit you, but it's not better because of the S/N.

With very few (though notable) exceptions no matter what the top voltage rating is on the RCA preouts for any given HU you'd not see that much current coming out of them excepting at full-bore volume running a test tone.

It's much less important than many people give it credit for.

Not unimportant, mind you, just not nearly so crucial as some folks would lead you to believe.

Any differences in preout voltage can be made up with an external line driver anyway...want a solid 8V going to your processors/amps? Easy to do regardless of what head unit you like //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Buy a head unit based on features you'll use, not specs you won't notice.

Nice HU without a doubt. You should enjoy it just fine.
