flyingdm,

You won't be able to. There are two ways of connecting your sub, either in series or in parallel and nothing in between. In series you get a 8 ohm load or in parallel you get a 2 ohm load. If you want to get a 4 ohm load with two sub, then you would want to get two sub with a 8 ohm rating and then connect them in parallel to get your 4 ohm load. I hope this help.

It all depends on your set up and the limit that is put on the amps by the manufactures, so check your manual before you do any bridgeing . What kind of amps do you have? Most amps are only capable to be bridge at 4 ohm. If you want to bridge the two 4 ohm subs I suggest that you wire them up in series. The amp would be more sable this way. If you connect two 8 ohm sub together in series you will get a 16 ohm load.

You can wire it the way the diagram shows above. It will present a 4 ohm load. I have used this configuration many times and there is nothing wrong with wiring it that way!

bberman, you're thinking of 2 DVC subs.... You can't make 4 ohms from 2 SVC 4-ohm subs.

Dragonrage Thanks I was thinking that he had DVC I must not be able to read. Sorry flyingdm you cannot have a 4 ohm load you can only wire them in series (8ohm) or parallel (2ohm)
