Boat Radio Installation

Bought a new radio for the boat and of course it doesn't have the same wiring harness. I'm going from 4 wires (Red, Black, Green - right speaker, Blue - left speaker) to a wiring harness that has 12 wires.

Blue - Remote Turn On
Black - Ground
Red - Accessory (connect to existing ignition circuit or switched 12 volt source)
Yellow - Memory (connect to battery circuit or constant 12 volt source)
Violet - Right Rear +
Violet/Black - Right Rear -
Gray - Right Front +
Gray/Black - Right Front -
Green - Left Rear +
Green/Black - Left Rear -
White - Left Front +
White/Black - Left Front -

The boat has 4 speakers but they all ran on just the 4 wires. Is there anyway for me to hook up the new wires to the 4 existing connections so the radio will work. I don't have a remote for the radio and I won't be programming the pre-set channels.

you could hook the yellow and the red together and hook them to a hot or battery curcuit lead. The memory will draw very little power, and this will allow you to have presets, the clock and to run the radio without the boat ignition on.

If you have 4 speakers, but the pairs are wired together, you can just use the front or rear right and left wires and tape off the others. Or you could run separate wires to each speaker, it isn't very hard.

I will try that.

You may already know this but if you have a trolling motor you don't want to run anything else off the battery that runs the trolling motor. They put off a lot of interference.
