Query: Works well for my application

Using this on my IDQ12. They are pretty durable and I have thrown lots of crap on top of them. I have lots of tools and random junk floating around in my trunk and this grill adds maximum protection over say a bar style grill. Granted it isnt perfect for it as the mounting lip on the idq is around 1/3 inch thick and these were designed for a sub with a very flat mounding lip. I just angled em up and they still hold onto the lip of the sub well. I would give five stars except for that issue and the fact that they dont come with screws so I had to make a separate trip to the hardware store to buy screws.
