I plan on making a custom box for a sundown xv.3 15 i’m pretty new to audio and subs but i know general terminology. The box will go in the back seat of my 08 gmc sierra im taking out the small seat and just gonna put it on the floor so the size isn’t really an issue. i want something that will hit hard at and is tuned pretty low. like i said im pretty new to it all and some help would be appreciated.
