Factory Sub and new amp
 

I have just picked up a OEM sub box and an audiobahn amp to drive it, I just wanted some general advise about matching up the 2 dual coil subs.Looking at the back of the subs it states 8 ohms, so with a stable 2 ohm output on the amp, wot would be the best way to wire up the subs.Is it best to match the 2 ohms by a mix of series and parrallel wirring or is it better to be safe and go for 4 ohms or more.
Thanks.
