tuned at 32ish,it peaked at 39 hz. I tried a 40 hz tone and spl started going down. the box i have aint the greatest, it was thrown together very quickly and was not very well thought out. I think i could gain a few tenths with a better box. i could probably get mid 46's on music with a box and deadener on music but the only way to find out is to do it. I was really wanting to get 150 with 2k watts but it dont look like its gonna happen.
That was my bad on the SS comment, still a kick *** looking truck
