Ohms and resistance. 3 d4 subs close to 1 ohm?

[Twistedmister]

I'm curious how close to 1 ohm I can get with 12dvc d4s. Straight parallel I get.  Straight series I get. But when I start mixing the two I get confused.

If I parallel the first two all the way I end at 1 ohm.  If I add a third, parallel to itself but then series to the other 2, does that put me at 1.25 ohms?  Is there a formula that can be used for mixing and matching series and parallel?  I read somewhere that the last sub that's in series would see less power.  Is this true or would they still split it evenly.  Thanks in advance for the help.

Ok.  Thanks.   I guess those are really the only two ways to do it.  I was thinking running the third woofer parallel to itself but series off the other two woofers.

Those are the only ways to do it. If you tried what you were thinking, you'd end up with unequal distribution of power.

That's what I figured.  Thanks.

Wouldn't 3 4 ohm Dvcs be 1.33 ohms?

2x2x2/2+2+2= 8/6=1.33??

each sub would have a single resistance of 8 ohms then divide that by 3 not 6. just wire it down to .67, your amp should be able to handle that if it's a 1 ohm stable amp.

U better have a HO Alternator and batteries at .6 cause your electrical is gonna take a pounding and if it can’t handle it your amp will probably blow.

Yeah. I have a 250 and an extra battery.  I'd probably go with the 2 ohm load and get a bigger amp.  I have the xtr 2500 and it gets hot enough at 1 ohm.  I have fans but .67 ohms sounds scary.  Haha
