The blue wire is used to connect an external amplifier. For the hot wires use a wire test light tool to locate the lead to the battery and ignition.
Use ferrite rings or RF coils around electronics to dampen radio frequency interference.
How to wire a radio in a boat. Black wire goes to the ground red yellow and blue wire go to the positive all other colored wires will go to the speakers positives and neg any power or g if. Wiring a stereo in a boat. Come on folks – you dont want it required that you have the key on to listen to the radio - especially if this boat happens to be an IO or a four stroke outboard.
Key on ignitionecm powered. There are two power feeds in a boat. One in the engine harness that goes to the ignition switch.

When pulling larger wire bundles stagger the wires where attached to the snake which both reduces the profile of the joint and makes it easier to pull around tight bends. Include and leave an extra pull string in place when pulling wire or coax to assist with future installations. By Frank Lanier Southern Boating January 2019.
Terminating a stranded wire for Insertion in a Screwed Terminal Block Stranded wires cause problems when inserted into screwed terminals. Do not solder the strands together as this causes a mechanical weakness. Either fit ferrules or solder on a small piece of 2mm 2 solid core wire and fit a short piece of heat-shrink insulation.
A shaft on the rudder protrudes into the hull where a small servo actuates it in either direction. The radio receiver and electronic speed control ESC for the motor are usually enclosed in a single waterproof casing. Emerging from this casing are the radio antenna rudder servo cable battery wires and power onoff switch.
Connect the power cord to the keyed connector on the power pigtail Connect the antenna and any other accessories. Install the radio in the mounting bracket and connect all cables and accessories to the appropriate jacks and connectors on the back of the radio. The installation of the antenna is separate from the radio.
A limited amount of zip ties is the best choice as they can snag if wiring need to be worked on. Never pull zip ties into a chase. Use ferrite rings or RF coils around electronics to dampen radio frequency interference.
You can get em cheap and they can be huge for removing trolling motor interference on electronics screens. Its known as the ground wire and it connects to the negative terminal on your boats battery. This is known as the memory wire and its always connected directly to the positive terminal of the battery of your boat.
The blue wire is used to connect an external amplifier. The remaining wires are to connect your marine speakers which typically come in four sets of two wires for each speaker. These are different solid color wires.
The most common method is to use the RCA pre-amp output jacks on the back of the stereo. Some are embedded right in the chassis of the stereo like this. Others are on wires extending out from the stereo like this.
You can identify them by the red and white color coding used to separate right and left stereo channels. The red wire is the hot wire and will need to connect to the positive terminal on the battery either directly or indirectly. The black wire is the ground wire connected to the negative terminal.
The yellow memory wire should always be connected directly to the battery and a blue wire to connect an external amplifier if so desired. You will want to run the main power wire directly from the amplifier to the positive terminal on your boats battery. Avoid wiring to a fuse box because those fuses are typically not rated high enough for the power an amp will need.
You will want to use a separate inline fuse on your wire. Determine the appropriate wire size needed to power the head unit. Run a red cable from the vessels fuse or distribution panel to the head unit.
Remove the fuse or turn the breaker off. Strip the insulation from the wire and install a ring terminal with a crimping tool. Attach the wire at the terminal block to the red wire coming from the head unit.
The back of the stereo is usually supported behind the dash with a bendable metal strap. There is a bolt on the back of the chassis. Push this through the hole in the strap and then twist on the nut to fix it in place.
The front of the stereo can be attached to the dash in several ways. For the hot wires use a wire test light tool to locate the lead to the battery and ignition. Connect the power and ground wire to the battery.
Make sure to match the polarity. Now that you have your boat stereo installed it is wise to. Borders Model Boat Club Wiring Model Boats This article is intended to explain the basics of wiring a radio controlled model boats.
The first The speed controller ESC must have a current rating which matches or exceeds the maximum current which the motor can draw ie when it is stalled. Make a drawing showing where the wiring will be. Make a rough drawing of the boat looking down from the top.
This is what designers call a general arrangement and shows how the boat is laid out. Using your schematic put in where the equipment fuse boxes buss bars switch boxes and wiring are going to go. The power wire coming from the stereo is usually red and likely will connect to a red wire from the car.
The ground wire for the stereo will be black as will its corresponding wire from the car. If there is no ground wire you can secure the ground cable to bare metal in the body of the car to serve as a ground.
