The reason of having hi pre out voltage is to combat niose...when ur amp receives a low voltage from the head unit it increases it to a higher voltage and current. This voltage is music. the problem is may be the electrical noise..If you turn the amplifier gains down the electrical noise is amplified less, but so is the music. The higher voltage head units put out more so you can still get satisfactory volume with the power amp gains reduced thus the system sound to noise ratio is improved.If you do not have random electrical noise coming out of your speakers, then higher voltage head units will not make any difference for your particular installation.

using Pre which have higher voltage pre out volts
will also let relax to amplifier/?
the more voltage from prevolts , the less of gain will be turnup
so amp will not to work harder ??

leave every thing !

Think of a simple logic

when u use divider voltage divider network T......to which extent ur amp heated up ? more heatup means efficinecy loss ....usually class AB amps ya jis ko aap 4 channel kehty hain they are 60 65% efficient while classd are 75% efficient y is this so ?? think of it ?...when u divide ur pre out voltage by using T what happened and when u removed that T what happened ?? and always remember gain of amplifier just adjust wid the volume of ur deck

han i got the point
thanks , i remember u told me gain of a any amplifier doesnt work after 75% or slightly 80% ,
so as lower the gain will open by high prevolts
it will easy to get best output from amplifier

next thing
is it possible to get connector of pioneer??? the back one ,
which is connected to the jack of pre ,
is all connector of pioneer are same?

geforce (geforce) 2009-04-15 14:26:00 +0600 #125

removing T connector ,now i set lower to gain , approx 60%
while on that amplifer i use to open above 75% with the previous pre some times 100% but nothing happened above opening 70%

lakin phir bhi garmion mai din kay waqt amplifer gets hot after playing music at 30 volume continuously 20 mins

Maggi (Maggi) 2009-04-15 18:23:00 +0600 #127

garmiyo mai itna to hota hay bhai :S

geforce (geforce) 2009-04-16 01:39:00 +0600 #128

mai samjha kai heat hi nahi hota

sorry copied previous question (u havent replied)
is it possible to get connector of pioneer??? the back one ,
which is connected to the jack of pre ,
is all connector of pioneer are same?

Maggi (Maggi) 2009-04-16 11:08:00 +0600 #130

yes its easily available

no such amp exists which never heatup while playing subs uthalo koi sa bhi hi end stuff amp lazmi garam hota hai aik level tak

thanks buddy

i missed this

4ohms dvc wiring has 2 options listed below

bahi yaar us beam pass ki dimension batado jo tum nay alizzz ko dilai thi , 308d2 , audiobank wala

an amplifier is said to have 500rms and 1500 peak power
what will be power at 1 volume by deck ( turning off all effects)) from pre??
i dont think so , i will directly hit 500 ,
but as we increases volume the power increases
then what we have to with 500rms?
u see
lets suppose an amplifier produces less then 20w @ 1 volume
and at max volume it hits totally 1490 watts
where rms power will have to work , if it says rms , the continuous power is 500rms

Maggi (Maggi) 2009-04-22 14:56:00 +0600 #135

yar us ka dimensions i dont knw box bara sa rekha hua tha jaga ke hisab se lelia

i dont think so , i will directly hit 500 ,
but as we increases volume the power increases
then what we have to with 500rms?

who said this to u ! bhai when u increase volume watts are increased NEVER. rms increased NEVER then what is the factor ke awaz zada anay lagti hai ? chachu it is db decibel ur ear cannot listen to WATTS niether RMS it only reponds to db so u are wrong ke rms incearse and watts increase aysa koi scene nahi hai werna ap ka amp d2 ke 4 tukray na karday ??

LOLZ

yaar yeh poochna tha k
i have got 75A total fuse rating , and i have 43A battery
so from where my amplifer will take 75A to give peak power

geforce (geforce) 2009-04-22 15:11:00 +0600 #137

the general formula for calculation power
Preal=VÂ² / R
Power=voltage x voltage / R
i got 40 volt by testing , as i got the way to check out rms and setting gain
where resistance is 4 ohms
power=40x40/4=400rms

my amplifer say that it is 400tms @ 4 ohms
i agree
and it also says that it is 600rms @ 2 ohms
i dont agree , even its stable @ 2 ohms

so Power=40x40 / 2 ohms
= 800wrms?
as my amplifer said 600rms
by formula i get 800rms
what is this ??

at 4 ohms rms power is 100% from amplifer
at 2 ohms rms power should be 200% , but my amplifier porduce 600rms instead of 800rms

an amplifer will produce 1 time more power (200%) as we take half of resistance

geforce (geforce) 2009-04-22 15:20:00 +0600 #138

Audio bank kaisa hai ?? 1600w wala 2 ch , what are its fuse rating?

Maggi (Maggi) 2009-04-22 15:28:00 +0600 #139

first of all if u need to check ur exact rms u must have bass boost 12db on ur amp wid 75 to 80% gain open and bass closed from HU ..do u have sine wave to check ?? ya aysy hi krnay beth gay

tumhara d2 400rms pe chal raha hai chalo kabhi dekhaingy
