Hello can any one direct me to the sub woofer fuse location ?

There's no fuse. It is ran directly to the amp in the trunk.

Can I install the HK subwoofers if I have the Hi fi system?
Thanks guys

Physically they will certainly fit….no problem there…..

but,
In my case the connectors did not fit, so I used adapter cables.
I used the HK subs from an F20, because they have the same impedance (2 ohms) as the original hifi subs in the f10….. the original f10 HK subs have an impedance of 8 ohms….. so depending on which amp you are going to use, you must consider your choice…. My expectation (and this is not tested in reality) is that the original hifi amp is not able to handle an 8 ohm sub…. Power to the subs will be decreased with factor 4!! (8 ohms is 4 times higher than 2 ohms)

Good luck!
