Thanks for taking the time to leave a review. We leave a slight gap on the backside so wires could go under the rack if needed which was a request from our customers. For the front side, we mention at the top of this page '- Requires removal of front plate on storage area', this is for the trucks that have a plate so we can extend the rack to fit amplifiers that are up to 7.5-inches. At 6.5-inches, the rack becomes too small for most high quality amplifiers at this height.
If you notice the slight slope of the floor under the rack, we poked out the rack to meet this slope, so when a underseat enclosure goes under, it meets perfectly to the enclosure. This was a way for us to extract more surface area. On the newer trucks with the underseat storage, you will see this rack fits like a glove and retains this storage area.
If you are unhappy with the rack, you can reach out to us and you can send it back for a refund.... Any questions, please let us know.
