Hey boys and girls... i want to build a false floor to mount my amp in my ek hatch. Basically i wanna replace the existing floor piece and make my own one but want it fixed in place.

However, i can't seem to find a decent mounting point, like an existing nut/bolt that i can fix the false floor to. Besides the bolt which holds the rear seat in place (i think that's wot it does) that sits in the gap at the base of the rear seat (wen looking from the boot), there is no other bolt in site.

Was wondering if anyone has done this before... and if so how did u guys go about doing this? Can any of the pro installers gimme sum tips?

And i don't want to mount it on the back of the seats. Thanks.
