Re: drilling into trunk floor--need some help
are you securing it down as a theft deterent purpose? because the weight of your false floor and amps, and box on top of that should prevent it from sliding arround. not to mention typically false floors follow the contour of the vehicle. so it wont slide arround any way as it is a custom fit. Are you sure you need to secure it down to the floor? You can go under your car and drill holes from undernieth that way you know you are not drilling into anything. and then use wood srews from underneitheth as you secure it down. that way is the easiest way. Fool proof as well.
