setting gains (thank you DECAF)

[Decaf]

speakers disconnected and set. and dont forget to put all the setting (bass, subwoofer lvl...etc) at zero as well.

thats not true

on alpines u need to put it at 15of15 usually to get 2v

my jvc needs to be 12of12 to get 5v

my friends pioneer gets 4v at 0 on a scale of -6 to +6

its the loudness/bass boost/bbe/ccc/eq features that need to be at 0

[Torres]

ah really? i was always under the impression to have everything flat. i gotta see if my el cheapo jvc one has subwoofer on it. doesnt even have bass or treble. just fade and balance lol. but that's what i was getting at at least...the EQ settings. but i'll keep the subwoofer in mind. learn something new everyday haha

Not to thread jack but if the bass setting can go into the negatives (alpine) should I turn it all the way down or just to zero?

There is no such thing as a jack when it come to questions that could help out more people than the one that asked. JUST SAYING...

but back to the main question sub connected or not.

F-that I'm going to poll this bioch

lol nice choice of words

sorry couldn't help it.

Thanks for asking this though,learnt from this thread,thanks to those who answered with the info as well

well on an eq yes it should be flat... but depending on the headunit the subwoofer level controls the voltage going out the preouts... in my case it made a drastic difference and the gain went from 4/5s to 2/5s

usually i leave it at 0 in those cases... like alot of the "deh" pioneers

If you have a problem with a crap ass pironeer radio post it somewhere else. Sorry to piss ppl off i had nonthing but problems with them.

OK. Back to the main question.

SUBS CONNECTED

or

SUBS DISCONNECTED.

RIDDLE ME THIS!!!!!

Because if they are disconnected how does the amp know what ohm load it will be at when they are connected.

I know oms law and that you have to have "A" and "B" to get "C".

So lets say Ohms is = to "A" and Watts is = to "B" and "C" = to voltage.

How do you get "C" if "A" is not present in the actual equation.

[Decaf]

u make no sense

again.... 1200w@ .8ohms

the square root of the rms u want to set it at... (1200sqrt) = 34.6v

multiplied by

the resistance the amp is seeing when using a dmm.... 34.6v * .8ohms

equals

voltage to set amp.... 27.7v

[77-AUDIO]

How do you know the resistance when SHIT AINT CONNECTED.

[Decaf]

ok i will try this again. did it several months back and it didnt work. thats why I was asking how do you know the resistance when SHIT AINT CONNECTED.

How does that make no sense.

simple math A+B=C

if u want to set ur amp for 1500w with a sub that reads 1ohm

then the voltage would be 38.7v using a -3db test tone @50hz

it makes no sense because u dont know phyics... a+b=c means nothing... i dont even know what u mean, lol
