will the gains on my amp being too high, affect the SQ?

[Slaugh 10+ year member]

hey i have a alpine 9815 doing the bi-amplification for my comps on a alpine mrv-f407 amp... im using the hu internal xover and i think my hu has too weak pre-outs, so i got my gain for the tweeter set on 2v and for the woofer below 0,5v //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

im asking if i should just set both to 4V (minimum of the amp) to have better SQ and less distortion levels or if thats just plain bullshit?

the volume isnt even very loud i tell ya... ive heard other setups with their gains on minimum and sounding much louder than mine //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

are there sub-level controls on the HU?

Some headunits won't put out a full voltage if the level is faded.

thats the amplifier for my comps... i have another amp for the sub

it wont affect SQ but when driven too high it will begin to distort

it all depends on the voltage the amplifier is putting out at the speaker terminals... refer to gain-setting tutorial and find out how many volts AC the amplifier should read, maximum, and then keep it under that number (with test tones, that is)

also make sure that your head unit has subwoofer at +15. for Alpine head units, in the manual it says that +15 is actually +0dB, and +0dB is actually -15dB and so on

It could certainly affect sq if, by cranking the gains, he now has hiss in the system.

yeah im also worried about hiss on my system... not that i can really hear it easily, but with gains on 4v it's barely impossible to hear....

where do you guys with Alpine 9813/15 leave the gains for your stereo???

buy a dmm and set your gains properly. trust me on this

what is a DMM?
