Nice sounding box but abit tall.

The following review is for NE121P, which is a part of the bundle you are viewing.

Great sturdy box, carpeting was nicest done only thing i disliked about it was its hight it too tall my trunk is 14.75. But this thing is 16" tall had to cuz the foam that was under the mat to make it barely fit and also re.oved the back seat...it was worth it though, im running a rf-p3d2 12"
