I ordered a Cobalt 232 with the factory installed wakeboard tower. I did not get the optional tower speakers because I plan on adding my own. I was looking through the brochure and noticed in the picture with the tower speakers it looked as if the wire came out at the base of the tower (by the windshield) and plugged into/went into the hull outside the tower. Is this how it is? Do I need to get in touch with my dealer and see if I need to do something to make my boat/tower "ready" for speakers? Thanks.
