Red protection light stays on. The only wires connected to the amp are the blue remote wire, the ground wire and the 12v wire. What does the red light indicate?

Disconnect all the wires except the three main power wires, ground, 12v battery and remote. Now, turn on your radio, if the protect light is still on then there's an internal short in the amp. If the light turns green, then there's a short in either the auxiliary cables or the speaker outs. If it turns green, then troubleshoot the other wires that plug into the amp by connecting them one at a time until the protect light comes on, which will tell you that there's a problem with that speaker/aux wire.

Havin problem with a1200 class a/b amp it ligts green and red at same time after hooking in remote how doi fixdo i need diagram to fix


Make sure you don't have any shorts on your speaker wires or rca cables. Unplug one at a time, the turn on power until it stays green with no protect light, then you know what input is causing the short. If you remove all speaker wires and rca wires and all you have connected is the ground, power(12volts) and remote and it still lights up red/green(in protect mode) then your problem is the amp.

I need a fuse diagram for 2001 Nissan Pathfinder


Do you want to install a new unit or wht ? u may use this reference to work upon ....
Get yourself a digital multimeter. Find the +12V constant, 12V remote, and ground. Connect them to the new head unit. For speaker wire get yourself a 9V toy battery and listen to poping noise. If you have a factory amp you need to power up the factory amp. Use the wiring diagram below to serve as a guide. Test your wire first before connecting them.

When just wblue wire is connected red light comes on


This sounds normal. The light comes on when there is 12v supplied to the blue wire (remote input). Need more details. brian.small@bobstgroup.com

What colour are the power wires, are they green & yellow, black, black & grey, blue & grey, red & grey or black & green. I want to connect a cd/radio player but don't know what wires connect to the cd...


JVC KW-AVX800 The black wire is your ground The yellow is your positive 12v constant so connect this to the wire that has 12v when the car is off. The red connect this to the key switch wire meaning the wire will have a 12v signal only when the key is tured to the on position. The blue is for a power antenna the blue/white stripe is if you have external amps this wire goes to the amps remote on The orange/white stripe connect this wire to your cars dimmer switch Happy Wiring

Red protection light


If the amp is going into protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.

With your multimeter set to DC volts, the black meter lead 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 lead 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.

If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp almost certainly has shorted output transistors and will need to be repaired.

My sony xplod 1000w xm-1652z doesnt work anymore


First off, according to the manual, the protect light should be green. That's normal operation. If it is red, that's a problem.

If it does go red, disconnect all of the wiring to the amp except the +12V and ground. Short the remote connection to the +12V to force the amp on. If the protect light still lights red, the issue is inside the amp and will need repair. If the issue goes away, try reconnecting one wire at a time until the protect light goes red again.

Protection Mode? amp wont start


With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.


If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
