Cory, on this board in particular, you should be more careful posting remarks that can come across as being condescending or snide in nature. For what it's worth, when I read your comment, my first thought was that you were insinuating that someone who spends a lot of time doing stereo work is wasting time because he or she should be riding instead. Who cares how someone uses their boat, so long as they are enjoying themselves?
"Jason" obviously has a passion for high end audio and building killer systems - for all we know, he could also be a killer rider. However, the point of this thread is obviously to show off a sick stereo build and the impressive results thereof - not anyone's riding skills. It would be like you starting a thread about riding and posting a vid of you learning a new trick and someone else making the flippant and off-topic comment: "well, got any vids of your stereo components".
Anyway, as to the OP's video, that's friggin impressive. Great stuff! I've only got one XXX sub in my A22, and I can't imagine what your system sounds like. I hope you've got a defribulator on your boat, 'cause I'm pretty sure that amount of vibration is going to put someone into cardiac arrest.
