ok I got it now, didnt realize that those little speaker things were dual vc, no why in the heck did BMW do that? that is jsut pathetic, 5 inch dvc speakers for subs?
on another note, I had disconected the two 5 inch and my stereo sound exactly the same, well almost it was a little less balanced but still same amount of ...well bass, if that is what you call it. but then put in the sub and wow. now I jsut dont know if putting in the amp is worht it? It sounds good to me without and I dont want to be gansta style but at the least I guess with the amp it will be sound quality difference.
