i was just looking at some dual 6 ohm voice coil subs made by ma audio. just curious how you would go about wiring these suckers. one, two, or even three?

 

It depends on the amp and what it is stable for....
Personally I'd wire them these ways:

1: wire them parellel to get 3 ohms

2: I can't even think of a way to wire these and get anywhere in a descent ohm range... you'd be stuck at either 6 (subs wired parellel, voice coils in series) or less then 1 ohm, .75 if my math was right (all of the sub wired parellel) and most amps can't handle that.

3: Same kinda problem, either 6 or even lower ohms.

Someone correct me if I am wrong, but that was the reason I bought SVC subs because at 4 ohms I could run a pair of SVCs at 2 ohms while DVCs left me with the option of 1 or 4 ohms... neither of which I liked.

Even a bigger problem with 6 ohm subs because then you have 6 ohms instead of 4....

 

Well, since each coil is 6 ohms, you can wire them so each sub is 3 ohms. Therefore, in a single sub system, the amp would see a 3 ohm load. This is slightly less then 4 ohms, and just about any quality amp should handle a 3 ohm bridged load just fine. If 2 subs were wired in parallel, the amp would see a 1.5 ohm load, which is what i used to run with my JL 10W6s. If 3 subs were used, you would get a 1 ohm load which most comp type amps can handle.

There can be only one!!

In a single sub system coils wired in parallel it will be 3 ohm.
With coils wired in series will be 12 ohm.

With two subs coils and subs wired parallel will be @ 1.5 ohms.
With the coils wired in series and the parallel they will be @ 6 ohm

With three subs coils and speakers wired parallel will pull down 1 ohms.
With the coils wired in series and the subs wired in parallel it will be 4 ohm.

 

so if you get a three ohm load its safe to run this into an amp at 4 ohms or 2ohms?

 

The ohm load on the Amp is determined by the Ohm the speakers are at.
So if the speaker is at 3 ohms that is what will be pulled from the amp.
