    Does anyone know what size is the subwoofer under the bed? Have anyone changed it before because I can barely hear it, i want to upgrade this whole sound system.

    A nice 12" ported box will fit under there nicely! Not all I'm sure, but the lucky random one I bought without measuring sure does!

    Woofers are pretty much built all the same. Probably more of an amp problem.

    I think it's 8-in ... I've wanted to upgrade mine as well especially in the 2020 trucks the sound system seems to have been downgraded somewhat vs previous generation
