Not my item, but I have the exact same box, and it fits perfectly between the strut towners in my TF - no tying down is needed. This is for your infomation only if you are trying to find a nice sealed box that you know will fit in you boot.

Some people have purchased boxes that didn't fit.....

I paid $115 at my local car audio place.

If you would like to know a few hints and tips on dropping your drivers into this box, just ask.
