Kenwood Powered Sub installing help civic 07 vti

hey guys i have a honda civic vti 07 model
jst got bak from japan and i bought a powered sub.. its called KSC-SW01

http://www.kenwood-electronics.co.uk...nent/KSC-SW01/

what i got a problem is.. where the power cable will go to.. cause the manual says to go from the in car fuse box so that it only runs when the car is turned on...
but the end cable is different.. so i cant find anywhere to plug it in and i dnt wanna strip the cables.. the cable has an fuse attach to it already too.

any help will be great..

or would it jst be easier to get a pro to do it at the shops?
i heard jb is costly.. but it shouldnt take too long since the amp and sub are connected so the only cable work u have to do is.. cable to speakers and battery.. and jst hide them.
