Ok, to start I have a 3000 watt class D mono block amp (stable 1 ohm). I also have 2 12'' duel 4 ohm subs and 2 10'' 8 ohm subs. I have it wired as each voice coil on the 12's in series which makes each 12'' an 8 ohm sub. And then i have all the subs (total: 4, 8 ohm subs) wired in parallel. Now would that give me a 2 ohm load or am i off some how? P.S. if anyone has an ohm calculater or knows were i can download one plz let me knowor even better any charts or so on. thx //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

I hope you didn't try to run that.....you cannot run difference impedence coils together, the 4 ohm subs are going to get almost all the power.....very simply you just cant do what you did.

Uh, no. Each sub is wired as 8 ohms. They'll all get the same power.
Your plan is correct Tazz, 2 ohms total.

 
Yep basically 4 4 ohm loads on the amplifier. 3000/4 is 750 watts per speaker. The power divides according to ohm's law. The dual VC subs will 375 per voice coil for 750 per speaker..

 
I misread the question....I though the VC's were wired in parallel which completley changes everthing (to the point where it does not work)....my bad on that one....you wanted a calculator, but you dont really need one, here is out it works:

Paralell: Rt = R1+R2+R3+R4......

Series: Rt = 1 / (1/R1 + 1/R2 +1/R3 .....)

its pretty simple, again, sorry for the incorrect info, just read your situation wrong.

evo d00d, whatcha smokin? You got 'em backwards //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

I stand corrected again....see that more less what I did when I first replied....what would we do without people like maylar ?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif (btw....im thinking about capacitors wired in parallel and series....dont know where my head has been latley).

 
one more thing, i really need something that would help me out with adding up ohm's if anyone has still? thx again all:p

I gave you the equations right there.
