1 15" memphis 15-PR154D subwoofer in a vented memphis box, fills the trunk up and its also a hatchback with the sub pointed right toward the back window. With suffecient power to this how will this sound? I used to have some crappy stuff that not even 100wrms was pushin, it it was actually hittin to tell ya the truth but im lookin for serious bass now and this is my first step towards it. The store I bought it from is called auto acoustic and I told them what I was lookin for and what price range and this is what they suggested to me. Now I may take the 15 back and buy a M3MOJO instead but for now I would like to get alot of opinioins.
