I don't realy know much about ohms or what they do, but which way is better?

I have a RF 800a2 amp if that helps.

Thanks!

 

6 ohm, then bridge the amp. Know how to do that?

 

I have NO idea how to bridge the amp.

 

You will need to use a series/parallel config for the subs. Follow this link, then click on the "Wiring your DVC subs" or something like that. On the next page, click on Two DVC subs series/parallel. That will scroll you down to the diagram.

To bridge on amp, you just use the positive from one channel and the negative from the other.
