Only had one "issue" with this box. When installing my new P3 the top screw hole is well above the face of the box. Fortunatly the P3 has 3 places for screws on the "corners" so I just doubled those up to ensure no air leaked out and there was tension all around the speaker frame to prevent warping. I love the compact design for the back seat of my extended cab Dakota. still a new box (less than a week) so I will see how it holds up. Thanks OCS for providing sucah a geat deal on this box! Half off MSRP, not a bad deal by any means.
