amplifer input sensitivity?

[hondarider 10+ year member]

Some amps say that there low level input is like 0.2 to 4.0 volts and i was wondering if that would work with my hu since it has 5 volt preouts? I think that even at the lowest gain setting it will still be to high.

yeah it never puts out an actual 5 volts on music. My ref 604 has input up to only 2.5 and my preouts are 4 v. No problems yet

it will work fine

If it's too much, just turn the volume down, and tune at a lower volume //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Due to the nature of music, and gain matching it's no issue. The hu only puts out that voltage when the hu is at max volume, usually only while playing a 1k test tone. If you set your gains at volume at less than a max hu volume, your HU cannot put out that voltage, unless you turn it up to where your amps will be clipping anyway. Combine that with the fact that music will only really usually be taking 1/10 of your voltage at a given hu volume vs a test tone at that volume and you have NO issues.
