im not saying that they are "little volume controlls"....but is there any proof that setting it to high has ever hurt anything???
has anyone EVER had a problem

just curious bc ive never heard of any problems with the gain controls

i agree 100%....ill share something with u all..

i have an old amp about 4-5 yrs and the "gain" control is labeled LEVEL and its like a volume knob which u can turn with ur fingers.

Newer amps have "gains" which u need to turn with a pricision screwdrive.....

i got the same thing nester..

ive just never heard of anythung bad happening with someone who has their gain set all the way up

ive found out the best thng to do is call your amp company and ask them how totune it....b/c as all of you know...everyone has a different thing to say on how to tune an amp gain and who else would know better than the company who actualy made your amp

it seems like they recently made up stories about gains in the past 4 years....lol

have u all really played around with ur gains

all they do is allow u 2 set the volume where u need it.

like if ur headunit goes to 50,and at 25 ur sub is drowning out ur components,u simple adjust ur gain.....

EXACTLY

the only time u dont even need to worry about doing it by ear is when you actualy know the input sensitivity range of the amp....(which some amps have that in the specs) and you simply mathc it to your head unit

also some amps actualy have the volts written around the gain knob

but if you have neither...adjust it to what sounds good

and another thing

people say that the gain is so important not tomess up

now heres a story..

i had all of my stuf instaled at circuitcity...everything sounded good and of course me being interested in car audio what do i do but mess with the gain.
turned it all the way up..the bass was too loud for the speakers and then it just got all messed up

i was scared to change it b/c of all tthe stories ove heard so i took it back to circuitcity...

again they tuned it but i wasnt pleased ...it didnt sound good

took it to best buy...this time with the loud OFF and the guy tuned it again

he told me to keep the loud off

but loud makes everything sound better....so then i couldnt handle the loud off soi turned it on and of course had to turn down the gain

now it sounds perfect....

and i tuned it without knowing anything really about the gain..(this was a while ago before i knew much about car audio)


soonce again....set the gain to what sounds good is what i believe....and that wont change untilli hear about someone blwoing subs bc of a gain problem

i just want to know

has anyone ever blown a sub bc of a gain control

i dont think so....and im no professional

but i called my amp company....and seen on various places on the internet that u turn the gain up to where it sounds good....and the subs dont start to distort


and if comnpanies advertise this in their manuals....you cant go wrong if you follow it

think about it...if your subs are not distorting..its not realy a great chance that they will blow IMO



im not pickin sides on this...it just seems that the gain is not as dangerous as it is madeout to be

from my prospective it also comes down to how flexable the rest of your sytem is....for example your system could be stock speakers off the deck and an amp running a sub or two or two amps and one running your highs and mids etc so its all about balance and flexablity as much as it is about setting the amp to the voltage and setting it so that various music sounds right because its recorded at a different level than the next

i totaly agree with that

i forgot to even talk about balencing your system..i was only talking about the sub part of it

but you are right IMO

maybe there is something to be said for individual line drivers in a multi amp set up

in all honesty though i was a little disappointed in my first three amp system...it didnt make as much difference as I thought but then again there were some areas i could have tweaked better....altho it seems simple is best in the end

u mean a difference in what?? stock speakers and aftermarket?

i think it makes more of a difference if u have an amp and some nice components
