3 ohm load
 

just curious, is it possible?

say if you had a 2 ohm sub and a 4 ohm sub wired into a mono amp. since a mono amp would bridge the two internally (what i learned from one of my other threads), if they were both 4 ohms then the final load would be 2 ohms, so if the amp is 2 ohm stable, and you had one 4 ohm and one 2 ohm, or say an svc 4 ohm and dvc 4 ohm wired to 2 ohms, my calculations say that the final load the amp would see is 3 ohms. is that correct, and is it possible? i figure it is because 3 ohms is more than 2 so it should be safe

i'm only asking because i have a dvc and a svc sub and from what i gather they're giving a final load of 3 ohms to the amp, which means i'm safe, right?

lol freshy

you would get 1.333 ohm if you wired it that way.

the formula is,

1/[(1/ohm)+(1/ohm)]

so you'd get 1/[(1/4)+(1/2)] = 1/0.75 = 1.333

the way you'd wanna wire that is connecting all 3 coils together.

ok Yuli you think you can help me out with this when I see you? I got bored today so I went and messed around in my van, I'll go put it back the way it was before I head to school

yah for sure.

its really easy, just take all 3 coils and hook them up together. your amp will work at 1.333 ohm, we tried the same amp at 0.5 ohm and it worked.....for about a month of solid abuse. at 1.333 ohm it shouldnt have any problems.

That's not entirely correct. A given mono amp may be 2channels internally bridged but it still doesn't do anything to the load presented to it. Show it 4 ohms and it sees 4 ohms.

There is also the problem of different power to subs in a common airspace.....even though the 3 coils will divide the electrical power evenly, if 2 of the coils are in 1 driver it will get twice the power of the other one and create enough new problems that you don't want to deal with....even if they are in 2 separate chambers it could still sound like crap.......:dunno:

he's not using enough power to run into a problem like that.

Alright, I'll bite.....why not?

Everything I've ever read on this issue says you simply don't do it.....the difference in response between the 2 drivers should be audible at any power level....if the box is in a trunk it would be harder to hear, but I still think he would be better off selling one or the other sub and getting a matched set......:dunno:

You can explain this to me on the 4th if you want....:laugh:

^^^ x2
I want to see a response to that too . . . I agree with BRG on this one

Someone actually agrees with me??.....:laugh:

Ok Yuli......you have the floor.........:worshippy:D
