I'm in the process of installing one on my tower now. I haven't got to hear it yet but will let you know. IMO it looks cool as heck and matches the boat colors perfectly. just gave them the hull # and they called the factory for gel coat match.
I'll try to take some today. Again I have not heard it yet but have it mounted and harness wires pulled. In the process of building a sub box and amp rack at the moment.
I just put one on a customers boat the other day. Loud as hell. The six back give a good amount of sound back a few feet. The 2 facing down really seem to help fill out the sound of the interior spks. And they have always built a quality box.
