    Do you know the type of amp? I have never heard of any other than a factory amp not having markings at the connection post.

What does the wire that comes out of the back of the amplifier that says REM hook to?


It connects to a fused, switched 12 volt power source; one that comes on when the radio comes on, preferrably the blue/white wire from the back of an aftermarket stereo.

Where is the power switch, or how do you get the power running through to get blue light to turn on?


There is a terminal marked REM it's between the + 12 volt and Ground terminal.
The REM terminal needs a power source connected to it to turn the amp on and off. It's usually the blue remote wire coming off the head unit.
This turns the amp on when your head unit is on and turns the amp off when the head units off.

I have two amps one for my speakers and the other for my subs it was working fine but recently one of them turned off. I thought was a short circuit and bought a new one but still doesn't work. Its looped...


When running multiple amps you need a relay most of the time for the remote wire off the radio this is because the radio was built to power one not multiples. one 12 volt relay may help .check local car audio store. also when hooking up relay it has to have a 12 volt power wire connected to it usually the center pin on the relay is your connection for the power wire the you connect your remote wire from the radio to the relay then connect each amp independently to the relay. Hope this helps write back if not . and if so leave feedback

Where does the rem wire plug into


It plugs into the power antenna cord on your radio if your radio does not have a dedicated remote cord. The remote switch is so that you amp can detect when your radio is on and turn on too, or is off when your radio is off so as not to drain the battery

The power cable and the rem cable need to have different power sources. The best thing to hook the rem. to is a power antenna wire, or if you don't have a power antenna, you'd need to hook it to the ign. or accessory wire.

I have my amp hooked up but it isnt getting any power can you tell me if i have a bad amp or if i need the speakers and sound for it to come on?


With all amplifiers for a car, you must have the main power connections B+ and ground connected, and then you must also have the remote turn on connected as well. This is the way the amp turns on. It comes from the radio and is usually the blue wire from the harness off the back of the radio. When the radio is turned on, the blue wire gets 12 volts sent to it so it can turn on an external device like an amplifier or the power antenna. Make sure you have this connected to the amp and that the radio is turned on. Then check the voltages at the power terminal of the amplifer. You will have the ground, the main B+ of 12 volts, and then the turn on voltage of 12 volts. If you have all of these, then you need to troubleshoot it more. It will turn on without the speakers connected, but I am not sure why you would want to connect it without the speakers. It will also turn on without the RCA cables connected for the audio input as well. But just to turn on the amplifier, all you need is those three things i mentioned. Let me know if you require any further help.

Visonik 350watt Amp Doesnt Come On....


With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

Let me know if you have any other questions.

Blue amp light lights for 2sec


There may be more than one problem. The fact that the radio AND the amp are seeing a voltage of 7v indicates that the battery is weak or there is a bad connection somewhere in the power line.

It's also possible that the amp is defective (shorted output transistors?) and when it turns on, it's drawing excessive current. That would cause the voltage to drop more than normal. If the amp is drawing excessive current AND there is a bad connection in the power line, the amp may begin to blow fuses (depending on the reaction time of the protection circuit) when you repair the power line problem.

No Power :( NEED HELP


Check the connection with the subs. See if all wires are connected or check for any break in the wire. Also make sure that the RCA's are connected to the subwoofer output at the back of your deck. Also check setting on your AMP.
