How can you wire a dual 1.4 sub?

What are the different outputs?

Dual 1.4 DCR (DC Resistance) meaning dual 2 ohm. In Series you get 4 ohm a speaker, in parallel you get 1 ohm.

da fuck

^ Which means you get it, or do you need more help?

I have just I sub. Can I wire it to a 2ohm load?

You can wire one amp per voice coil to get 2 ohm per coil, but if you have just one amp, you would need to wire both so that leaves with 1ohm or 4ohm setup

no you cant do that

My amp is 2 and 4ohm stable. Will it configure either way?

 

[badandyturbo 10+ year member]

Ok I got it figured out.

A 2x1.4ohm sub can have an output of 2.8ohm or .67ohm.

Yes, and that is DC Resistance (DCR) when you by a 4 ohm speaker that is its nominal rating, the actual DCR of a 4 ohm speaker could be anything from 3.2-3.7 (just examples)

Here this is what i came up with.

You seem to have the DCR and ohm mixed up. Your sub is dual 2 ohm. You can't get 2 ohm. As knuconceptz said, you can wire it 1 or 4 ohm.

Your top diagram is 1 ohm (.67DCR) and the bottom is 4 ohm (2.8DCR) check any subwoofer spec sheet, it will list DCR and then Nom. Impedance. DCR of a 4 ohm speaker will be in the 3.xx and it will list nominal impedance as "4"

Your bottom diagram is the only way to wire your amp safely. Now is the amp 2 ohm Stereo Stable / 4 ohm Mono Stable? If so then that amp would b great for that set up. An amp that is 2 ohm Mono Stable would not be optimum for your application, you did not specify that.

How much power does your amp put out at 4 ohms? You may be better off getting an amp that's 1 ohm stable...
