While securing, make sure you keep enough clearance around the box so that it can breathe and there is no build-up of heat.

You can attach the adhesive strips to the bare wood or fiberglass-made subwoofer boxes. But the boxes are mostly come covered with some sort of cloth or carpets, which may need to be cut according to the size of the strips for securing the box perfectly in the vehicle.

Test it Out

Now, give the box a good test to see if it’s secure. Try to move it around and see if it budges at all. If everything seems good, then you are ready to go!

If not, make some adjustments until you are happy with the results.
