I have a new sub and amp due to arrive any time now. Does anyone know the best way to wire up a single dual 4 ohm sub with a 2 channal (bridgable amp) I am fairly OK with electrics but never done much with speakers and dont want to blow a brand new setup.

 

mate google a wiring diagram as you will get a good idea.

The above link is how to do it and reduce the ohm down to 2 ohm's which will place more load on the amp and thus more power.

Its your choice and depends on what you want sound wise.
