Ok I have two 12s that are dvc 4 ohm. My amp is only 2 ohm stable. From what ive been looking at the only options I have seen were 1 ohm or 4 ohm and obviousley 4 ohm is my only option between those 2. So basically im just curious if theres any way to wire them at 2 ohms because I want to be able to push them properly. Thanks in advance.

 

Somebody correct me if i'm wrong, but from what I remember in my high school physics class, if the two subs are 4 ohms, if you wire them in parallel that should be 2 ohms of resistance.

 

Well there are a few ways to get the 2 subs to run @ 2ohms. If you are running 1 amplifier to each of the subs and each sub has a dual voice coil (DVC) that are 4ohms+4ohms, you simply run the wires in parallel to the 2 coils on the back of each speaker. If you are running the 2 subs from one amp, wire the 2 subs in parallel and the end result will be 2ohms.

(R1*R2)/(R1+R2)
(4*4)/(4+4)
(16)/(8)
=2ohms

 

You cannot configure (2) D-4 DVC subs as a 2-ohm load. The original post was correct. Only load configs are 1-ohm or 4-ohm.

 

Thats what I thought. Thanks k67. Time for a new amp.

 

I dont get it.... why not? what subwoofers are we talking about?

 

Your calculations are correct. However he has (2) DVC subs. Each sub could be configured as a 2-ohm load. Together, they can only be configured as a 1-ohm or 4-ohm load.

 

Don't forget that EACH sub has TWO 4OHM voicecoils. And he wants to wire those two subs together.

4OHM:

1. SUB 1- Wire the voicecoils in parallel. (Wire the two POSITIVES together. Same with the NEGATIVE) The sub is now a 2OHM sub.

2. Sub 2- Wire the voicecoils in parallel. (Wire the two POSITIVES together. Same with the NEGATIVE) The sub is now a 2OHM sub.

3. Take the POSITIVE from Sub 1, and connect it with the NEGATIVE of Sub 2.

4. Take the NEGATIVE from Sub 1, and connect it with the NEGATIVE on the amp.

5. Take the POSITIVE from Sub 2, and connect it with the POSITIVE on the amp.

1OHM:

1. SUB 1- Wire the voicecoils in parallel. (Wire the two POSITIVES together. Same with the NEGATIVE) The sub is now a 2OHM sub.

2. Sub 2- Wire the voicecoils in parallel. (Wire the two POSITIVES together. Same with the NEGATIVE) The sub is now a 2OHM sub.

3. Take the POSITIVE from both subs, and wire them to the POSITIVE on the amp.

4. Take the NEGATIVE from both subs, and wire them to the NEGATIVE on the amp.
