A quick update:
This stuff:
Yesterday from Lidl's I got some 3M velcro type stuff though it is more the hard plastic and double hook type heavy duty. I bought to hold down sub to carpet in my other car. They had packs with strips and circles to.
Link below 3M slef adhesive pads, if do not work type in postcose and see under current DIY offers.

Is brilliant. I simply stuck a circular piece over the guide holes in the liner. Liner's held firmly, but is removable if necessary. Top tip, thanks Chap!
Glad it worked well, I have used it to hold down sub in my ford puma!
