wiring amp to subs ?

if i bridge my 2 channel amp , how do i wire my twin vibe subs they are cbr120 ?

longmill pharaoh ra-003

vibe cbr 120 twin enclosure

do i wire them in series or paralell ?

Here is a wiring wizard:  http://www.sounddomain.com/shop/wooferwizard.pl

Enter the number of subs and the voice coil configurations.  You want to end up with an impedance of 4 ohms or higher to bridge across a two channel amp.

so i need to wire them in series to my bridged amp?

As far as i understand my speakers are 4ohm single voice and i have to end up with 4 ohms so i wire them in series?

That is amp+ to + then - to other speaker + then - back to amp-

I hope that is right please let me know as i am installing today.

thanks, (i know i might sound daft but it aint easy)
