You will use this on the inside of the enclosure and then bolt it from the front? Since the box is already built, how will you entrench this firmly into the MDF? Just by tightening the bolt from the top? Confirm whether this is a good technique. If this ever loses its grip on the MDF and hangs loose inside, you'll have to cut open the box or the bolt shanks to get your subwoofer out. Plus, will the sub's gasket allow a bolt head to sink into it?
