On the 2005 Marlin 300 there are two sets of speakers that came installed. One set is in the bow and the other set is in the helm area port and starboard. Both run at the same time. First question. How would you separate the speakers so they run separately, like an a and b switch so I can listen to music outside and the munchkins can watch tv without listenign to good old CW music. Second question, if I wanted to add a set of speakers for the cockpit, where would be the best place to put them. I see some people have speakers mounted by the hard top near the spreader lights, but I have a bimini top. Thanks.
