It was about 18x24x9 and had this in it 
I hooked it up with my 3/8 valve that’s currently going to my shockers that i learned has a bottleneck right before the valve, guess i was working on it late and therefore couldn’t go to home depot or lowes for more fittings, and holy hell this thing is loud. Doing 75 on i-20 with the horns facing backwards in the bed and it sounded like they were right there next to me.
I wish a box would turn up out of the blue for me!!
Yeah, especially a box with horns.
