It looks like a first time DIY built box. The speaker mounting holes are offset and terribly spaced. One side the subs are almost touching and the other has 1-2 inches between. The bed liner spray was done extremely poorly as well and there is wood visible through the port. The port is done terribly and you can hear very bad chuffing when playing music. Worst of all box doesnt sit flush on under the seat and moves when driving. Its under the seat of a 2021 Sierra 1500. Box doesn't sound good at all and looks terrible.
