I got an alpine type r 12 and an amazing box made from Starr Mountain Sound, I was flexing windows of a local business with just one 12 on less then 1000 watts. But I want to be able to safely stay that louder then 1500 now so I want to get an HDC3 12 and just put it in the box I have considering I just recently got it a few weeks ago. It is tuned to 33hz and 2cu feet. 32x15x14 I think it was, but I could be off. I want to run around 1500+watts daily to it.
