Sub hitting grill

[trod2902 26]

I have an ssd 10 under the back seat of my nissan titan and im havin problems with it hitting the grill i have on the box when it pounds. Ive been adding wood to create more space between the sub and the grill but i was wondering if there are any other techniques i could try. Any help would be appreciated.

A different grill or spacing.

ya but the box is now sitting on the grill and not its feet so i think i will just redesign the box and build it myself, the other box was built for me for $250

You need more clearance for downfiring than a grill anyways...if it is truly resting on the grill it is hitting that isn't good.
