There are speaker wires, or what appears to be speaker wires under blank off plates on the tower, where the bimini top zips on. After removing blank off plate, I found a black, red, blue, green, yellow with black stripe and yellow wires. I am assuming that black and red are stereo power + and - ? When I connected those to the speaker black and red wires, I did not get any sound out of the speaker. A wiring diagram would be much appreciated at this point.
