Scratch & Dent Stealth-Pod by Select Increments for YJ and TJ Wranglers.  There's some slight warping in the plastic and around the subwoofer hole.  But the adhesive gasket installed around the ring is closed-cell neoprene which will fill in any tiny gaps between the pod and your subwoofer for the proper air-tight seal.  You must supply your own subwoofer, amp and wiring.  All hardware for installing the pod is included just as would be for a brand new, normal pod.  First 3 images are of the pod and hardware you'll receive.  Remaining images are stock images for illustration purposes.  Free shipping is for the lower 48 only.
