Hi mate, I've not attached it to the floor yet as I can't be bothered to remove the seat. I may do and cut the carpet out give it a little more clearance. Or I may stick it in the boot modify the cubby box in the side. At the mo It's being held in place by the rear mat and gravity
But over all I'm impressed with the quality, after reading revues saying they aren't worth the money I was a bit sceptical, but thought im not going to be after massive bass just something to round the system off. It does that perfectly and is as loud or as quiet as I want it. Deffo worth the money
I'll pop a pic up when I get time
