Haven't built it yet but got the download fast with no issues seems like it should work
Awesome design got it installed in my envoy and it has already shook my rear view mirror off. Lol
was super sick
You get the download within seconds of purchase. Great box, the 18's hit super low and loud, the box is pretty huge, but what would you expect for this kind of box right.
