Thinking about a amp

MonsterPower · Posted: Mon Jul 07, 2008 8:41 am Post subject:

guys u all think that a stable currant system comes from a better alt but in fact a stock alt rated @120A will perform better idling cold than an upgraded alt which needs to idle at 2000rpm.. so in this case stock alt will be better ..

once booom can get max currant from that alt i.e the big 3 upgrade and his batteries are fully and properly charged with correct guage wire runinig from front to back with proper grounds he can safely burp with a voltage drop up to 12.5 up from 13.5

a proper power foundation on an average amp will beat a very bess amp on a shitty power setup ... thing is spl is just not about the amp as other factors come into play like box design ,power transfer and install

actually slacker u confusing amps with subwoofers..

most class d amps the more u load them .. in terms of the lower the impedence the more power they will output .. i.e some amps give alot more than rated power at 0.5 than at 1 ohm or even 2 ohm ..

now a subwoofer no matter hwo u wire it will not raise the ratings .. if it is 500wrms if u parallel it it will not handle 1000wrms

however i have powered subs with well over their rated power and never had them burn ..

So why not shoot for the safer 1ohm load?

pioneer in spl comps pple try to squeeze every possible watt out of the amp .. if u start to read up on the stuff pple do ... in trini pple just read a magazine and see soundstream 6500d doin these number so they rush out and buy it then to realise it doesnt put ot those power cuz some pple runing the amps at half ohm and 16v of currant to get the maximum power out ot fhe amp

now i am not applying this to daily playing nor sq which i know boom is not gonna do

naw, i meant hose idiots down by me think that if you wire subs down to 1 ohm you will be "louder" than if you wire the subs @ 4 ohm.

I hav an idea of how the amps config does usually go: 250 rms @ 4 ohm, 500 rms @ 2 ohm, 1000 rms @ 1 ohm if it capable of goin down to 1 ohm etc. most cant go down to 0.5 ohm (like some ah de ever popular boss chaos 1000).

but what i meant like with respect to amps, they believe that the 500 rms from a 4 ohm stable amp putting out 500 rms @ 4 ohm (cant go lower than 4) is less than the 500 rms that you will get from an amp that puts out 500 rms @ 1 ohm.

^^^

yuh mean the only 2000watt 0.5ohm stable amp?

cuz i think rf hav 0.5 ohm sable amps.

MonsterPower · Posted: Mon Jul 07, 2008 1:12 pm Post subject:

most amps dont give u .5 ohm specs

as well as this amp gives specs in bridged mode which is 2 amps daisychained together

slacker_jack · Posted: Mon Jul 07, 2008 1:25 pm Post subject:

ok, nah looks like i was mistaken, rf eh hav 0.5 ohm amps...

so what's the use of burping an amp with a stock alty?

sundown and co. recommend using an upgraded alty...for the sake of your car...

^i believe that's the category

pioneer i think u really need to open ur mind..

db drag street class mandates that u compete with 1 battery 800si with engine off..

yes still pple doin over 155-160..WITH ONE BATTERY !!!!! no alt power .. why u think they doin that

alt dont make a diff once ur currant system is stable.. some ple burp at .5 ohm with a voltage drop of 1.5v at most

look at some of the tests on termpro.com

*sigh*

wrt to amp in question

pioneer as much as u know ur reaidng .. u should go out sometimes

in the real world sometimes winnig a competition means winning by .1db yes .1 db

so if u competing an prepare all ur life and get beat by .1 db just cuz teh other team did it
