They are 4 ohm dvc subs can I wire them in such a way that they will run at 2?

It'll either be 1 ohm or 4 ohm, no matter how you look at it. Unless you get a Veritas Accumatch, which you can select what impedance you want (I don't know too much about them or which one you would need).

...or, you could take a matching amp and use 2 -- one to each sub.

If you want to wire 2-4ohm DVC subs to 2ohms, you cant.

click here to find out why.

In order to wire DVC subs to 2ohms you will need 2-2ohm DVC subs.

Click here for wiring diagram.

or 2-8ohm DVC subs.
sry, i dont have a diagram for that.
It would wire as follows.

sub #1: + to+ and -to- will bring an 8ohm DVC sub to 4ohms. do the same for sub #2

then wire the subs to each other as follows:
connect + from sub #2, to + sub #1
connect - from sub #2, to - sub #1

Now connect sub #1 + to amp + (for one channel amp)
and #1 - to amp - (for one channel amp)

Good Luck.

^^ Yup [img]smile.gif[/img]

To make it simple. If you have one 4ohm DVC you can do it!
If you have two or three 4ohm DVCs you cannot.
If you have four 4ohm DVCs you can yadda etc.

Here is the simple math

When wiring in parallel you simply take the impedance of each coil and add them.

When wiring in series, you reciprocate the numbers (4 ohm becomes 1/4 etc) and you add all of the numbers together, then reciprocate the final number (3/4 -> 4/3ohm = 1 1/3 ohm) i hope that helps.

What he said, only the other way around ;)
(series add, parallel reciprocal)

Shoot, I confused series and Parallel! :mad:

Thanks for catching my blunder and correcting it [img]graemlins/thumb.gif[/img]

If it's a mono amp your out of luck but if you have more then one channel your good ta go. Just run each sub in parallel and use one channel for each sub, but only if your amp can run 2ohm stereo. [img]graemlins/thumb.gif[/img]
