u may need to look into a forums or pages related to repairing car amplifiers because some manufactures do not give service manuals or schematic diagrams to the public.

The red light you describe on your amp, is the protection mode warning light. An amp goes into protect for many reasons. Here's a checklist.

1st check the fuse (s) on your amp and make sure they are not blown.

2nd check the inline fuse next to your car battery (if you have an inline fuse)

3rd, disconnect the speaker wires with amp on, does the light go off?

4th check your ground, this may be ok if you have tried another amp with the same wires.

5th.if none of these turns the protect mode off, it may be an internal fault.

you may have blown transistors and it is a tricky job to repair and costly.

HI, if the unit is in protect mode then there may be the possibility that the speaker wires may have a short circuit in them or that the amplifier section may be damaged....you can remove the radio from it's sleeve and check the wiring behind the unit...this also would have to be done to see the model number and serial number...it should be on either the top or bottom of the unit...the speaker wires for this unit are the white, gray, green, and violet...each with another of the same color but has a black stripe in it...the black stripe is the negative side of the speaker wire....you can disconnect these wires, then turn on the unit to see if it comes out of protect mode...if it does, then there is either a bad wire somewhere in the car or a bad speaker...if the unit stays in the protect mode, then you will have to take the unit in for repair, as this indicates a circuit failure

One of the more confusing car stereo problems can be when an amplifier goes into protection mode. One minute it's working and the next minute it's not, usually with the green power LED on the amp turning to red or orange. Here's a brief troubleshooting method that will hopefully help you if your amplifiers ever go into protection.

1. Try to determine the cause. Amplifiers can go into protection mode for several reasons. Knowing what happened before it quit working can help determine how to fix it. Did the amp malfunction as soon as it was turned on? Did it happen after blasting for hours (may be thermal overload and it needs to cool)? Did it cut out after you hit a bump (a wire connection may have come loose)?

2. Tear it down. Get the amp down to it's most basic state. Remove all of the speaker wiring and RCA wiring and leave only the power, ground and remote leads connected. If you still have a problem in this state then either your amp is defective or you may have an installation problem such as the amplifier touching metal.

Remember that an amplifier should only be connected to the vehicle through the power and ground terminals. Mounting the amplifier to the metal of the vehicle, including putting the mounting screws into metal, can cause problems for your amplifier. Always mount the amplifier to a non-conductive surface. An easy way to accomplish this is to mount the amplifier to a wood board and then mount the board to the vehicle. Don't let the amp touch the screws used to moun the wood board and don't use screws so long to mount the amp that they go through the board and touch the vehicle.

3. If the amp is OK in this torn down state start reconnecting wires until you find what causes the problem. Add the RCA cables first. Then add the speaker wires one at a time. If the speaker wires cause the problem then they are probably touching metal. Check to make sure that a speaker wire isn't being pinched somewhere between the amp and the speaker. Also check that the speaker wire or speaker terminals aren't touching the vehicle metal near the speaker opening. Rear decks and door panels can easily touch unprotected speaker terminals if not properly installed.

If you believe your amplifier is defective contact the manufacturer first. Many have flat repair rates that are very affordable and cover parts and labor as well as return shipping. However local repair shops may be cheaper if it is just a small repair. Compare the manufacturer's repair rate to that of a local shop. If you don't know the reputation of the local shop it may be better to send it to the manufacturer who will have working knowledge of the amp and parts readily available.

Hope it helps..

The red light indicates that your amplifier is in protect mode. Amps go into this mode if there is something wrong with the setup of the system to prevent fatal damage to the amplifier circuitry. This is bad thing since the amplifier will not function until the problem is solve and it can remove itself from protection mode.

Amplifiers can go into protect mode for many reasons but one of the most common is incorrect mounting. Is your amp sitting on the metal of your vehicle? Is it bolted down and screwed into the metal of the vehicle or your seat? The amp should never be touching any sort of metal. Only the ground should touching the metal of your vehicle.

Speaking of grounds, many people often neglect proper grounding which can cause an amp to go into protect mode. Do you have a solid ground? Is the wire less than 3 feet long and directly connected to a non-painted metal part of your vehicle? Is the ground wire the same gauge as your power wire?

These are just a few reasons why an amp can go into protect mode. You can find more information here. Or simply google for why your amp is in protect mode.

there are 2 reasons for it to be going into protect mode 1 is heat 2 is the load on it. if it is going into protect mode soon after it starts there is a problem with the speaker. if it is after it has been on for a while it is that the amp itself is overheating. hope this answers your question

is the remote source have enough amp to triger amp seem like that is you prob and chk you spk wire and rca too-

If the protection LED is lit, the amp is in protect mode and probably has shorted output transistors. To eliminate other possible causes, read through the following page:
