I am running 4 OA 15s and gonna be giving them between 2400 to 3000 watts (depending on how well they handle the power). I am expecting at least a 150db out of them (I know when playing music it varies but I'm saying it's capable of 150db). I need to deaden my roof. I am wondering if I should do 2 layers of Damp Pro or if one layer of Alpha Damp will work just as well. My roof is about 30sq ft and right now I have about 30 sq ft of damp pro so I'd only need to buy another pack of the damp pro b stock which is 36 sq ft for 120$ plus shipping. The Damp Pro is only 20 sq ft for 150$ plus shipping so to do a full layer on my roof I'd need to spend 300$.
So my question is is 1 layer of Alpha Damp = 2 layers of Damp Pro?
