tuner357 Posted November 5, 2011 Report Share Posted November 5, 2011 Hey guys. Im doing 2 15" dd 9515's and im wondering if anyone has done 2 15"s in there silverado or sierra? Im really not sure about my box size and all that im still kind of a noob when it comes to building box's. I want the box to be tuned to 33 hertz. Could anybody be able to help me design one? And also what is maximum rms people have been running on 9515's? because i have a stetsom 11k2 d and im not to sure what i should wire it do yet. But anyways if someone could help me design a box that would be great! i also have been hearing that if i have the port facing the rear window i could get more db out of it? dont know if thats true or not. thanks to whoever helps!

bigmescan Posted November 6, 2011 Report Share Posted November 6, 2011 Most will say subs up port facing drivers seat for #'s. I had one 15 facing forward and port up in middle of box and was louder to the ear but not good on numbers but was good for lows. Was in a ext cab dodge 1500. But that's just my opinion.
