Hey guys, I did some searching but didn't really find what I was looking for.

I have a 6th gen coupe that I'm wanting to put in a single 10" sub, but I want to mount the box to the car so it won't move around as well making it harder for theives to take. I also want to keep the box small/just big enough because I still use my trunk for other things. I've heard of "L" brackets or bolts being used, but I'd like to hear from those who have done this and what they've used for doing this and what works best. My biggest thing is that I'm not 100% sure where it's safe to drill or bolt around in my trunk.

ANY input is greatly appreciated! Thanks in advance!
