Preout Voltage

I'm researching several different headunits and trying to decide what features and benefits make the most sense for me.

I do have a question I tried the search but still didn't fully answer my question.

The higher the preout voltage the better? Is a headunit with 5 volts considerably better than a 2 volt unit? It will be paired up with a pbr300x2 & BT 7.1's.

Thanks

Per UltraNutz and others minimum is 4V - the "higjher" the better. I use pre-outs (4V) on my deck (had PBR300x2 and now SS 4.520).

you can alwaysa use speaker outputs if needed.

I'm running preamp outputs from my Sony GS500R to my PBR300x2, 5 volts, sounds great! Preamp outputs give a cleaner signal to your amp, as long as the voltage is high enough for sufficient volume I would always use the preamps, YMMV.

I would use the RCA's for that one.
