When I bought the boat, I got the package with the tower Rev 10s and 4 speakers cabin speakers. I now want to install some bow speakers. Are there speakers wires ran for both sides of the bow? I dug around and found some available for port side, but couldn't find on the starboard. I did also notice there are 2 opening on the back of the head unit...do they need to be plugged in there?
Thanks in advance
