Your definition would be wrong, not to sound rude, but to me, "aftermarket" means just that, After Market. You can purchase After Market speakers that are far superior to your stock ones. I would be interested in knowing or seeing pics of how Bennington beefs up the railings to support it. I guess even though you haven't had any problems yet, keep in mind that Bennington builds these boats to last a long time and thought that was the best way to go. Who knows, even though I only got my boat a little over a month ago, maybe I need to upgrade something already! I never actually thought that much about the power bimini, but maybe it would be nice to have. My dealer also gave me a price on the boat and options I originally picked, then as I started to 'add' options, he gave me cost as well, or at least what I thought was a very fair deal on them anyway. As a question, can your old top still go on? I haven't seen one installed, so didnt know if it made a mess of the rail. For now I guess i'll just stick with my poor boy bimini top. haha
