Im trying to find or build my own box for my Chevy Silverado ss. I would like to put in one 12in sub in a ported box under the back seat. If someone could give me plans or tell me where to buy it would be very appreciative thank you

usually @Buck ; would get you a design, but i believe he is ill at the moment.

Whatever you do, don't purchase a ported box online that is prefab. They don't have the airspace nor port area and sound like ***.
