Whether installing on a car, truck, boat, UTV, or golf cart, among the most usual amplifier installation issues we troubleshoot entails the remote rotate on wire. The remote revolve on cable is responsible for transforming your amplifier on and off.

You are watching: What is rem on a amp

This blue cable (typically through a white stripe), may be even an ext important to recognize than your standard power and also ground wires because if the isn’t mounted correctly, your amplifier will not turn on also if the has good power and ground relationships OR it might constantly attract power and also drain your battery over night.

WHAT go THE REMOTE revolve ON wire DO?

The remote revolve on wire receives voltage from the factory electrical system as soon as the ignition is in the ACCESSORY or ON position (keep analysis this record for the finish explanation). This voltage is transferred with the remote turn on cable to the amplifier turn on circuit; once the amplifier senses this voltage, it turns the amplifier on.

When the ignition that the vehicle is turn off, the remote revolve on wire stops carrying voltage and also the amplifier transforms off.

If the remote rotate on cable is connected to a cable in the vehicle that has constant voltage, the amplifier will constantly be on. If the remote rotate on cable is associated to a wire that does not get voltage once the ignition is in the ACCESSORY or on position, the amplifier will certainly not rotate on until that cable does get voltage.

The blue/white strip remote rotate on wire has a number of other names such as accessory wire, system remote manage wire, etc… some of the confusion about this wire may come indigenous the various wiring methods in between a factory and also an aftermarket head unit.

One point to note, most head unit wiring harnesses likewise have a heavy blue wire. This cable is frequently for strength antenna or manufacturing facility amplifier rotate on, do not obtain this wire perplexed with the remote turn on wire through the blue/white stripe.


An aftermarket head unit commonly has a plainly marked blue/white wire consisted of in the wiring harness. Wiring the remote turn on wire with an aftermarket head unit is quite straightforward. Simply connect one more piece of blue primary wire to the blue cable in the wiring harness and also run the primary wire ago to the amplifier to end in the remote revolve on terminal.


To affix wire come wire, an appropriately sized butt connector or other format connector have the right to be used.


For stock head units, wiring the remote turn on wire isn’t fairly as simple, yet is still easily done if you monitor the ideal steps.

Since a stock/factory radio doesn’t have actually a remote revolve on output prefer an aftermarket head unit, the voltage rotate on signal has to come from the factory electrical system. The remote turn on wire should be associated to part of the vehicle"s electric system that only turns on when the ignition is in the ACCESSORY or on position.

Some that the much more common options for connecting the remote turn on wire as soon as using a factory head unit are to the wire associated to a power antenna (older vehicles which carry out not turn off the antenna when not utilizing the radio) or to the vehicle"s fuse box. Due to the fact that the remote turn on wire is short current, it deserve to be associated to virtually any fused calculation terminal (such together the one for the radio itself) as lengthy as it just powers up when the auto is on.

(To make certain you choose a fuse that only receives voltage as soon as the ignition is on, you can test v a multimeter before connecting the wire.)

Since the manufacturing facility wire is currently terminated on both ends, splicing right into the wire is necessary. Usage a T-tap connector or reduced the manufacturing facility wire to splice right into the wire by twisting the remote rotate on wire together with one finish of the factory wire, then crimp top top a butt connector. Next, reconnect the factory wire by inserting the other end into the open finish of the target connector and crimp. This will “tap into” the wire for the remote rotate on but likewise reconnect the wire that was cut.

We recommend wrapping all butt connector relations in electrical tape or warmth shrink.


Another alternative for providing a appropriate remote turn on circuit is come wire continuous power and ground to a switch and then cable the calculation of the move to the amplifier"s remote rotate on. This method you deserve to manually manage when the amplifier turns on and also off through the flip of a switch. The problem with wiring the remote revolve on this means is if girlfriend forget to flip the switch to the off position, the amplifier will stay on creating a draw on the battery when the vehicle’s electric system is no charging, i m sorry could result in a dead battery.

Wiring remote turn on to a switch is very common in off-road car installations such as UTV’s, ATV’s, next by sides, etc...



After her remote revolve on wire is mounted or if you ever experience any amplifier worries that are power related, girlfriend can conveniently test your remote revolve on wire with a multimeter.

Just choose you would test power and also ground, you can test your remote rotate on wire. V the ignition in the turn off position, location the positive lead the the multimeter ~ above the finish of the remote turn on wire and place the an adverse lead of the multimeter to a ground connection point. Be sure the confident lead is touching the wire strands within the coat of the remote rotate on wire.

With the ignition in the turn off position, there must be no voltage.

Then revolve the ignition come the on position and also test the same means again. While in the on position, there have to be 12+ volts at the remote revolve on wire.

If you have actually 12+ volts when the ignition is OFF, the remote turn on cable is connected to constant power.

If girlfriend don’t have any voltage if the ignition is ON, the remote rotate on cable either doesn’t have a great connection or isn’t wired come something the receives voltage as soon as the ignition is ON.


When connecting (splicing in) to existing wiring for aftermarket installations, over there are countless methods available. We space going to talk around a few of the more common methods. The best method to splice into existing wiring is come solder every splice and then safeguard the bare wire link with warmth shrink and/or electric tape. This technique takes the longest and also is the most expensive yet tends to be the most long lasting connection. Other frequently used methods encompass using butt connectors and also Scotch Locks. Butt connectors and t-taps are available in miscellaneous sizes for various gauge wire. The different colors obtainable reflect which dimension the connectors are.

Butt connectors (also referred to as barrel connectors) are basically a metal tube sheathe in plastic insulation. Come splice into a wire making use of a butt connector, you would cut the cable in the place where you want to download the butt connector. Then crimp one end of the wire you just cut into one finish of the butt connector. Next, you would twist the new wire that you space installing to the other end of the reduced wire. Then install the twisted end of the 2 wires right into the other end of the butt connector and also crimp this finish as well.


Wrapping the target connector with electric tape or heat shrink tubing protects the link from moisture and other debris.

Scotch Locks have tendency to it is in a less dependable connection but they are an extremely quick to install. They perform not need cutting the the wire you desire to splice into and also the splice have the right to be made with a single crimp.


Scotch Locks use a steel “guillotine” that when pressed into the wires, cuts v the coat of the wire to call the cable strands and also act as a conductor between the 2 wires.

Before pressing the “guillotine” right into the wires, you first place the Scotch Lock approximately the wire you desire to splice into. To do this, you slide the wire with the side opening and also into the channel furthest from the opening. Then place the wire you are including into the opening and inside the channel closest come the opening. As soon as you have actually the wires positioned correctly, start to near the top “latch” which forces the “guillotine” down v the wires and also eventually locks onto the bottom component of the Scotch Locks.

When using Scotch Locks, us recommend trial and error the cable you just spliced come make certain the “guillotine” is making a an excellent connection. Periodically the “guillotine” doesn’t cut all the method through the insulated jacket and also therefore doesn’t do a connection.

There are numerous styles the inline cable taps that could also be used; target connectors and Scotch Locks are simply two of the much more common options.


Do not run a jumper wire from power to remote rotate on:

One of the more common points we come throughout when troubleshooting amplifier installation difficulties related to remote rotate on is as soon as the amp will certainly not rotate on (often a an outcome of no running a remote turn on cable at all or connecting it to a wire that doesn’t get voltage when the ignition is in the ACCESSORY or ~ above position). An ill-advised equipment is to operation a jumper wire the end of the strength terminal into the remote rotate on terminal.


(Pic is just to display a jumper wire from strength to remote rotate on... You need to never use primary wire for power and also ground either)

Doing this will certainly make the amplifier turn on, however it will never turn off because it will be receiving continuous voltage. One amplifier that never ever turns off can develop a attract on the battery resulting in the car not gift able to begin if the battery is drained come a suggest it doesn’t have sufficient voltage to revolve the starter.

Do no wire your remote rotate on to strength antenna in more recent vehicles:

In enlarge vehicles, wiring remote turn on to strength antenna was really common and worked just fine because when the radio to be on, the power antenna was up and also working. However in more recent vehicles, the power antenna might only be receiving power once the radio is in AM/FM mode. If you switch to Aux input, CD, satellite radio, etc… the strength antenna wire will stop receiving power and your amplifier will power down as a result.

Understanding what a remote turn on wire does and also installing it appropriately will ensure over there is no unwanted current draw on the vehicle’s battery when the audio mechanism should it is in off. A little research to identify an suitable factory cable to splice right into for remote revolve on will certainly ensure the installation is excellent correctly and also avoid wasted time troubleshooting this frequently made DIY mistake.
