There are many things that you need to think about when you are wiring wakeboard speakers. The first thing is that there is going to be a lot of water around you. There is likely going to be a boat motor running too. Add some people to the equation, and there is going to be a lot of noise. That noise also disperses quickly as your boat powers through the water.
A lot of noise on your boat means that you are going to need a lot of volumes. A lot of volume means a lot of power for your speakers. The more power you can feed into your speakers, the more volume you can achieve.
Once you have your speakers positioned (see the section below), you can begin to wire them. If you have a newer wakeboard tower, then the tower may be already wired. If not, then you should try and wire your wires through the wakeboard tower. If your tower is already wired, then you will first need to position your tower speakers, and then connect each end of the wire; one to the speaker and the other to your amplifier or music player.
If your tower is not wired, then you will most likely have channels which will accommodate wires. Our pro-tip for feeding the wire is to use the safety-light wires. If you do have a safety light on your boat (or wires for one), you can tie one end of your speaker wire to an end of the safety wire, and then use the wire to pull the other wire through.
Be careful when you are doing this. If you find any resistance, you can apply some lubrication to the channel to make it easier. Take your time and follow the natural channels. Pull through some extra speaker wire, and you can use this to pull the light wire back through again. Once the speaker wires are threaded through any channels and holes, you can connect the wires to the speakers, and attach the speakers.
