kwik q? about preamps

[triphop 10+ year member]

are the rear outputs usually lower voltage than the fronts? (kenwood kdc mpv 619)

cuz i hooked up my sub to the front (i know, im messy but i had just about enogh of the install and just hooked things fast) and had a nice loud bump... later on i realized my mistake and switched my speaker amp to the front and sub amp to back... but it just isnt as loud as before.

peace

Not usually...go to Kenwood's site: http://www.kenwoodusa.com/ and check the specs though.

not usually, i would believe all outputs would have the same voltage.

It could change on how you have the fader set on the head unit. If you have your head unit faded to the front the front pre-outs will have a louder signal. But otherwise they should have the same voltage.

my kenwood excelon(x759) has 3 4.5 v preouts. If anything the front and rear will be a lower voltage than the non-fading, but i've never seen a HU that has a lower rear than front or lower front than rear.

well, there's a difference between rated and/or peak voltage and RMS voltage //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

there isnt a perfect number...

set your gains the way it has been described many many times before...

it will be very low...

set your headunit to a loud listening volume, turn gains all the way to zero, now slowly turn them up until you hear distortion, then back it off till the distortion is gone again...

basically...
