Not necessarily, could be internal fuse gone or just a burnt copper track, should be cheap enough to fix at a repair shop

I put a Pioneer AVH 1400 DVD in 06 solstice have it hooked up working but no sound through speakers I have hot ground remote and speaker wires hooked up what other wires have to be hooked up 4 sound


If the car had an amplified sound system prior to removal you will need to turn on the factory amp. You need to hook up the blue wire with the white stripe. You may have a dedicated wire that you need to hook it to or you may have to hook it directly to the 2 blue wires for the power antenna. Now you may not have a power antenna but hook them up anyway. If that doesnt work you have a dedicated amp turn on wire. If you find that and it still doesnt work check your fuses for the amplifier with a digital multimeter. Replace any blown fuses that you cant find

I hooked up my kicker ix1000.1 backwards now what?


if you have connected the power supply up backwards (crossed over plus to minus ) then im afraid you've damaged it internally , but if you have only connected the speakers backwards , that's not too bad . unpower it and ck your wiring to the speakers make sure all the speakers red or + goes to the positive or + on the amp and the negative goes to the other terminal

Hooked battery ou backward want crank


Ok. You have conflicting statements here. You say it won't crank. That is supposed to mean that the engine will not spin when the ignition switch is turned. Cranks but won't start sounds more like what you are getting at from the second statement that spraying gas in cause the engine to "hit" as you say. Am I to understand that you hooked the battery up backwards? If you did I'm very surprised you got that much to work. By your lack of knowledge of standard mechanic terminology, you come across as one who does not normally work on vehicles. I don't know what to tell you, but if you are careless (or ignorant) enough to hook the battery up backwards, the level of work that will be required to repair the electrical damage done by that act is most likely beyond your ability to execute. Take your car to a good mechanic or better yet, and auto electric service center.

I have a trc447cb radio, it kept blowing fuses, please help thanks...


This radio has been hooked up backwards. CB radios cannot be hooked up backwards or it will destroy it. However this is hope.

Because they can be damaged this way, there are polarity protection diodes in the radio that will blow if the radio is hooked up backwards, before it can hurt anything in the radio.

They are usually N1004 diodes. Is a big black diode that has a white stripe. And if it is blown, it will most likely be Black and burnt.

Open the radio, and look near the power section of the radio. It will be in the back near where the power cord plugs into it.

Look for a burnt black diode. That is the protection diode.

Get an N1004 or better from radio shack, and remove the burnt one, and put the new one in, making sure to put it in with the white strip on the same side as the original.

Once you have finished. Make sure the polarity is correct. Then hook up the radio, and turn it on. Should work fine.

If you want to validate that it is the correct diode, if you pull on leg out of the board, and turn on the radio, it will turn on. When the diode blows, it prevent the power from getting to the board, if you take it out, it will let it through. CAUTION. The radio will work again if you just remove the burn diode without replacing it. But if you hook it backwards again, it will be toast, and as good a door stop.

Dont know which is positive or negative on the back of my 10's


if you hook them up and they dont work then they are backwards. the model of sub that u have doesnt show positive or negative. it wont harm the speaker to hook it up backwards. just try it and see if it works.

Radio won't power up


The radio was most likely hooked up to power backwards. When you hook up the positive and ground wires wrong, it will blow the polarity protection diode in the radio.

The part is N1004 available at any radio shack. The number on the board is D23. It is located near the back right of the board when looking at the component side of the board. It may look black and burnt but not always. Replace it with another N1004 or better. If in a bind, you can just remove it and it will work again BUT!!!!

If you hook it up backwards again by mistake, it will ruin the radio.
