Here is a wiring wizard: https://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)

That is correct. It will be an 8 ohm bridged load. Your amp will most likely be capable of twice the power output with a 4 ohm bridged load, but with two SVC 4 ohm subs that is the only choice you have. (Or you can connect a sub per channel if you like for the same output.)
