Car audio speakers 12 volts and 24 volts are universal

The power supply voltage of the audio (** system) cannot be easily changed, but as a speaker for playback, there is no difference between 12V and 24V when replacing, only the impedance, power and external shape and volume of the speaker need to be considered; Regardless of the appearance factors, as long as the impedance of the new speaker is the same as the impedance of the original speaker, and the power of the new speaker is equal to or greater than the power of the original speaker, there is no problem in replacing it.

If the impedance is different, the output power of the audio system will change, and the impedance of the new speaker will be small, which will lead to the increase of the output of the audio amplifier and the damage of the amplifier; The power of the new horn is small, and the horn is easy to burn out due to overload. If these two parameters are the same, there is no problem with using them, and if the shape can be put in its original position, it is even better.

The impedance is the same, the power is not smaller than the original, and the audio and speakers will be fine after the change.

Summary. Hello, the speakers of car stereos are not divided into 12 volts and 24 volts. This one is generic.

The horn of a car is based on the power and impedance values of the horn. Common in-car stereos use an impedance of 6 to 8 ohms and a power of more than 25 watts, as long as they meet the standard, there is no problem. Don't choose too much power of the speaker, otherwise there will be insufficient power amplifier current, and the speaker will not be pushed to cause serious sound distortion and sound reduction, the original car tape recorder, the speaker is selected at 15 25 watts is enough.

Hello, the speakers of car stereos are not divided into 12 volts and 24 volts. This is for the pulsation chiropractic. The horn of a car is based on the power and impedance values of the horn.

Common in-car stereos use an impedance of 6 to 8 ohms and a power of more than 25 watts, as long as they meet the standard, there is no problem. Don't choose too much power of the silver speaker, otherwise there will be insufficient power amplifier current, and the speaker will not be able to push the sound will be seriously distorted and the sound will become smaller, the original car tape recorder, the speaker is selected at 15 25 watts is enough for base infiltration.

Isn't it said that it is easy to damage the circuit.

It depends on the resistance value and power of the horn, and how much voltage is used to supply the hood, and there is no problem with Chan Kuanchen. As long as the speaker meets the standards of the radio, it will not damage the circuit.

Summary. Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, the car audio speaker does not have a 12-volt voltage, this is the need to check if the insurance is broken, the insurance is broken and it will not be connected to the chain electricity, and the wiring harness of the speaker is broken and there is no voltage, and finally the power amplifier has no output signal or Sun will not have voltage, I hope mine will help you.

Typing, the voice can't be heard, it's the inspection advice given to you from above.

The driver's cab and the passenger cab are ringing, and the tail compartment is not sounding voltage.

Swap the front and rear horns, and check if the wiring harness behind is broken. Good.

The 12-volt relay cannot be replaced by a 24-volt relay, because the starting voltage is too low, the 24-volt relay does not engage and does not work, press the horn, and the horn does not sound. The relay is actually a power switch, when you press the horn button, it is not the horn button that is pressed, and the electromagnetic switch of the relay, because the voltage is too low, can not meet the requirements of the electromagnetic switch, can not connect the horn power supply, so the horn does not sound. Horn relay installation drawing:

Schematic:

No, because the voltage inside the car is 12V, you can't work with 24V.

It can't be replaced, and the relay will be burned.

If you want to connect the battery from the car, open the battery box, you will see that there are four square batteries inside, each battery has two binding posts, generally the binding post is marked in red is the positive pole, there is ** to connect the four batteries, the connection method is to connect the positive pole to the negative pole of another battery, this is the circuit series, separate each battery is 6 volts, and the series connection is 6x4 = 24 volts. First of all, you have to find out the two wires connected to the bicycle motor, these two wires are the positive and negative poles of 24 volt electricity, take one of them to connect to the audio (please divide the positive and negative connections to the audio when taking the wire), and the other wire is indirect from the short wiring of the four batteries, that is, put the four batteries side by side, the left two batteries and the right two batteries, and the wiring in the middle is the other wire you want to take. But you don't cut the wire and connect it to your speaker, you just need to connect it to the speaker and connect it to the speaker.

The middle line must be connected, and there is a line that is connected to the bicycle motor of the two wires at your choice, if you choose to receive the positive line of the bicycle motor, the middle line is the negative line (finger connected audio), if you choose to receive the negative line of the bicycle motor, the middle line is the positive line (finger connected audio).

If you have a little knowledge of circuits, I will tell you, simply put, it is to take the electricity of two of the four batteries and use it on the audio, and connect it to the audio without affecting the original circuit of the bicycle.

I think you already know how to wire a battery once you know that it is 6 volts.

Be careful not to affect the original circuit, and when you disassemble the battery box, you should see it before you do it.

Is it a two-battery deal?

If it's two batteries, it's two 12V strung together! That's a lot easier! Lead straight out of a battery, and you're good to go! If it's a single battery, it depends on what load you receive. If the request is not good.

Then buy a 7812 three-terminal regulator IC to connect it, if the requirements are too high, then there is no way! Go buy a 24V to 12V DC-DC switching power supply board.
