finkster Posted February 25, 2009 Report Posted February 25, 2009 My Panasonic head unit had 6 volt preouts...very efficient...Guess i never knew what i was missing lol... DAT 4125------>RE XXX comps active Eclipse cd7000 I serve drunks for a living
Boon Posted February 26, 2009 Report Posted February 26, 2009 It also affects how much you can turn the gain on your amp up. The higher the pre amp voltage, the more you can turn the gain on your amp up and still get a clean signal. LoLwut? Uh, no. IMO if you're setting the gains correctly (with a scope, the multimeter method mostly used on here is kinda wrong in a lot of ways...) then it's exactly the same. The only time a line-driver/high voltage preouts helps is if you're dividing the signal a lot or you have a lot of induced noise and want to use less gain on the amps. 10.x volts fo' life!
LooneyG Posted February 26, 2009 Report Posted February 26, 2009 MAKES A HUGE FUCKIN DIFFERENCE...i went from an AVIC-N2 to an AVICF90BT thats from a 2V to a 4V...let me just say my bass is tighter, seems louder and voltage stays a little better. Also my amp used to get REAL hot and smells a lil when bangin on it even on a short period...i drove home (good 15-20 min drive) blasting away....full tilt whole time....amp was cool to the touch and hardly ANY smell. and for once in a long time my ears are ringing a lil. i have a line driver but it gave me feedback so i took it out...ima re-hook it up and see if i can eliminate that noise somehow and get a lil louder. so when buying LOOK INTO PRE-AMP VOLTAGE I love my AudioControl Four.1 it makes a huge difference on output Voltage and clarity and Bass seem to be a lot tighter http://www.stevemeadedesigns.com/board/public/style_emoticons/default/hairtrick.gif "If someone aint hatin' on you, your doing something Wrong !!!"
Zade08 Posted February 26, 2009 Report Posted February 26, 2009 Same here. Went from a 2v pioneer to a 4v pioneer and god damn. Now if I could just find a deck with out the fucking rca hiss Id be set. Vehicle: 2001 Ford Escape Head Unit: Kenwood Kdc-x592 All out for a rebuild. New shit coming in the next 30 days.
creyc Posted February 26, 2009 Report Posted February 26, 2009 Quite a bit of misinformation in this thread, but hey if it makes you happy... A higher pre-out voltage does NOT allow you to turn the gain knob up higher, in fact it does the opposite. But because you can turn down the gain you're amplifying less noise with your signal, giving you a higher S/N ratio and lower noise floor. 2001 Chevy Blazer (2) SAZ-3000Ds (2) custom 18" Madmax subs in a second row wall Rockford 600-4 Pioneer PRS components Pioneer P800PRS deck
stayfly33 Posted February 27, 2009 Report Posted February 27, 2009 is getting a line driver just as good as getting a HU with a high pre-amp? or is it better to just get a HU with a high pre-amp from the start Bass is my drug. One hit and i was hooked.

stayfly33 Posted February 27, 2009 Report Posted February 27, 2009 the pheonix gold line drivers say it has THD 0.02% isnt 0.01% the most you should have? or can you even tell the diffrence? Bass is my drug. One hit and i was hooked.
