Agreed on choosing a product based on your application but I still voted Incriminator. I love their equipment and their customer service has been top notch. I've had DC and Sundown as well and enjoyed them. I feel DC is overpriced for what you get but solid products. As far as quality, they are all going to be quality brands (although I have no experience with Orion subs). I loved my Fi BL too. I was going to get Alphas but the build time was crazy long (I think they are caught up now though)
