Radio Wiring Diagram

Depends on the car. There is no standard.

Play some music, then touch each pair of wires to one speaker output of the unit (one pair at a time) and you'll hear which speaker is making sound.
Quick and nasty way to find out which pair goes to which speaker is to touch each speaker pair to a AA battery, which will pop the speaker loudly. This can damage a speaker though.

Why does my gem sound exa2955 amp keep blowing fuses?

You may have a bad speaker that does not have enough electrical resistance - low resistance looks like a short circuit to the amp.

You could also have a single fiber of one speaker wire touching the other speaker wire before they get to the speaker (that is, the two wires at one speaker are touching each other near the terminal posts on the amp or near the terminal posts at the speaker). Check all speakers.

your speaker wires are touching if the plus or minus or (red and black wires) are touching it can blow the amp this is a protection. Check all the speaker wires on the back and makes sure they are not touching.

Receiver doesn't turn on, trips out

sounds like a cross wired speaker, or a wire is touching either inside the speaker box, or the actual wires are touching at the terminals. this is simple to remedy unplug everything from receiver, then with it turned on and at a low but audible level. plug each one in till the problem occurs again. the time it occurs will say that you found the problem speaker. good luck. also manipulating wires often corrects any problem with wires touching accidentally.

My screen flashes protector and nothing will turn on

Have you tried to unplug and reset the reciever? Usually protector is on because of an overload.

Da30es protector error just scrows on the display

Disconnect all speaker wires at the receiver and power the unit back up. If it stays on, reconnect speakers2.gif one by one and test each time. You will either self correct the problem, (usually a braid or two touching the other terminal) or you will find the speaker or wire with the short. Once you find the speaker that's causing the problem, disconnect the wire at the speaker and test again. Be careful and keep the wires separated so they do not touch. If it still cuts out, replace the wire. If it stays on, your wire is good and the problem is in the speaker. For good measure, reconnect the wire to the speaker again careful not to have braids touch each other and test. If it still cuts out, meter the speaker on resistance to check for a dead short which is caused by a bad voice coil or bad crossover. If your not proficient with a meter, take the speaker to any home audio2.gif shop and have them test it for you. Most will do this free of charge. If you disconnect all the speaker wires and the receiver still goes into protection, it will need to be serviced. Once serviced or replaced, be cautious when reconnecting speaker wires and test the same way. 80-90% of the "protection" cases that I service are do to a shorted wire or speaker. Hope this helps

Won't stay on, turns off by itself

With a 1.5 Volt Dry Cell (AA Size), connect two pices of wire with the Cell. Momentarily touch the wires with speaker several times. It should produce click sound when wires are touched. If not then speakers are defective and need repair. Do not touch the wires for more than a second, touching the wires for a long time may damage the speakers.

Protect mode turns the reciever off at fairly modest volumes

I Had the same problem.

It occurs when you have a speaker wire touching something that it shouldnt and and you are grounding out the system. The system is going in to protect mode to keep itself from being damaged

In my case I found that I had a couple of frayed wires from one of my back speaker terminals touching the wire on the other terminal. This was all it took. I re-inserted the speaker wires on that one particular speaker and made sure they were not touching and problem solved.

I have a word titled "PROTECT" on my kdc mp333, how do I get it to function properly again? Pls reply asap.

When the stereo goes into PROTECT mode it is due to a speaker wire having a short circuit or is touching the car chassis somewhere.

Check all speaker wires from the unit to the speakers.

First check that each pair of speaker terminals at the speaker end is not touching. Or, a wire fell of 1 terminal to rest on another.

Best way to check if it's a blown speaker or a wiring short, is to disconnect all speaker connections ( at the speaker end ) making sure the disconnected wires don't touch each other or any metal in the car. press the reset on the unit and power up. If the unit powers up ok, then its a blown speaker.

Otherwise it's a short in the wiring.

If it's a blown speaker, you can connect 1 speaker at a time and the blown 1 will send the unit into protect mode again.

If it's the wiring, disconnect the unit from the wiring and use and ohm meter to check each pair of cables. A reading suggests a short.

If you don't have an ohm meter a battery and bulb will do. This method usually works on a short.

If you have no joy with either method, take each speaker wire in turn and check with a source of earth (anything metal connected directly to the body of the car, cigar lighter main body when pulled slightly out is good)

New car speakers cut out when I turn up the volume.

You just have to check all of the speaker wiring.It's a wire touching somewhere and it will do that till you fix it. What it is is just where the negative wire which is the ground for your spreakers it's touching the positive wire which is know as a power wire.When this happends it lowers the frequency of the volume which will cause the speakers to cut out and volume level to drop.
