Hey all,

Is it possible to wire up 3 DVC Subs to a 2ohm stable amp?

 

Yes.

 

Only if they are 4 ohm models, even then they come out to a fractional final ohm. Check out http://jlaudio.com/tutorials/wiring/index.html

 

You can do it with any DVC subs.

A 2 ohms DVC sub can be wired in parallel to create a one ohm load, then wired in series with each other to the amp to create a 3 ohm load.

8 ohm DVC subs can be wired to create a 5.33 ohm load buy running them in series, then wired parallel to the amp.

And obviously, 4 ohm DVC subs can be wired in series, then wired to the amp in parallel to create a 2.67 ohm load.

Any of those would be fine with an amp that can handle 2 ohms (bridged). Granted, the 5.33 ohm load wouldn't give you the most power output, but you gotta do what you gotta do.

 

Sweet my subs are 4ohm. I guess that will be the battle plan that I will use for the new stereo going in my winter car.

Thanks

 

Actually, running drivers in series isn't recommended because in a series circuit, when all resistances are the same( i.e. three 1ohm speakers), the first speaker in line will get more power then the second,the second more power then the third, and so forth. . Only in a parallel circuit will each speaker get the same amount of power to drive each sub. Is this correct?

If using 3 dual coil drivers,I would recommend getting dual 4ohm subs,wiring the coils in series,then parallel the subs to the amp.

 

Sorry try again. In a series circuit current will be the same throughout and if ALL the loads are the same resistance, voltage will be divided equally. Current stays the same, voltage divided equally, power divided equally.
E=IR
The power to each load would be the SAME......

 

My fault. You are correct NEEDAZ.

 

In all the electricity/electronics courses I've taken (3 to be exact) that was NEVER stated. Normally they don't state stuff that isn't true.

What is true is in a series circuit, the higher load will get more power. I.E., a 4 ohm and an 8 ohm speaker wired in series to an amp... the 8 ohm speaker will be louder/get more power.

That I do know is true. Is this perhaps what you're thinking of?

I suppose I could see that happening with a DC circuit, but not an AC circuit, which is what a speaker receives.

If what you're saying is true, isn't running the coils in series the same thing? Won't one VC get more power than the other?

 

Hay, AJ, read the post right above you're post. He just made a mistake.

 

I was just responding to him quoting me. That's all.

 

What I see is you're wiring six voice coils to one amp? Consider that bridged, the amp is using only the left channel from the stereo. I'd think about adding another amp and wiring two speakers (four coils) to the biggest amp and the other to the smaller on the other channel from the stereo head. Or something like that. Just a thought.

 

What?

 

Maybe there is something new out now? Most amps that I've had are bridged to mono. One input channel to both outputs tied together. Take a bridged amp and unhook each RCA input cable and see what happens.

 

Actually it's both inputs mono'd to one output 99.9% of the time

 

Sometimes 4 chnl amps will do that if you bridge them into 2 chnls by flipping a switch on the side of the amp. It makes it easier for someone to run subs that way instead of having to use 4 RCA jacks for only 2 subs. I know my Alpine is like that anyway.

My friend has a Profile amp (yes I still claim him as a friend) and even with it bridged he had to get "Y" splitters to hook up all 4 inputs on the amp even though it was being run in bridged mode.

But as screamin' said, 99% of 2 channel amps combined both inputs into a mono signal.
