How to connect the 12V7AH battery to the audio equipment

The 12V7AH battery should be used for the audio equipment, and the audio should be powered by 12V.

Connect the positive pole of the 12V7Ah battery to the positive power supply of the audio, and connect the negative pole of the battery to the negative power supply of the audio.

Summary. Hello dear, 12V7Ah battery is equivalent to 84 watts per hour, depending on how much power is used by the specific connected appliances to be determined. A battery is a general term for a battery that can be recharged and reused after a certain amount of power has been used.

The battery can also be called a rechargeable battery, the main principle is that the chemical energy of the two can be reversed after being connected to an external power source. There are many components of the battery, so the design will also be different, including the size of the battery voltage, the size of the battery capacity, the size of the appearance of the battery, and the weight of the battery. When charging the battery for the first time, the time should not be too long or too short, which will shorten the service life of the battery and also make the capacity of the charge smaller, so we should be cautious when charging the new battery for the first time, so as to extend the service life of the battery.

For general batteries, the initial charge should be carried out in accordance with the charging specifications before charging: for the battery of dry-charged lead-acid storage, the initial charge should also be carried out according to the instructions for use.

Below the sound connection 12V battery is a simple teaching skin compass:

Prepare tools and materials: You will need a set of audio system (including car audio, speakers, etc.), audio cables, 12V cables, screwdrivers, cable strippers, electrical tapes, fuses, fuse boxes, etc.

Turn off the power: Before operating, make sure the vehicle's power is off to avoid short circuits or other accidents.

Determine the installation location: Choose an appropriate location to install the main control unit of the audio system, usually on the dashboard of the vehicle. Make sure the position is securely fixed and easy to operate.

Connect the power cord: Use a cable stripper to strip out a small section of insulation at both ends of the 12v cable. Connect one end to the power input terminal of the audio system and the other end to the positive (+) of the vehicle's 12V battery.

Connect the grounding wire: Connect the grounding wire of the audio system to the metal part of the vehicle to ensure good grounding. The grounding wire can be fixed using screws or screws.

Connect the audio cable: Use the audio cable to connect the audio output of the sound system to the speakers or the input port of the car audio system. Make sure the connection is secure and not loose.

Install the fuse: Use a fuse and fuse box to protect the audio system and vehicle circuitry at the point where the power cord is connected to the positive terminal of the battery. Make sure to choose a fuse with the appropriate current level, depending on the power of the sound system.

Check Connections and Tests: Make sure all cables and lines are securely connected and not loose or short-circuited. Restart the vehicle to test if the sound system is working properly.

It should be noted that the above steps are only a general tutorial and may vary depending on the sound system. To ensure the correct and safe installation of the sound system, it is recommended to refer to the audio system user guide or consult a professional for installation. In addition, pay attention to the electrical safety during the installation process and avoid touching the high-voltage part to ensure safe operation.

The 12V horn can be connected to the battery to work with a simple circuit. To connect a battery, two important electrical concepts must be understood: current and voltage.

Electric current is the flow of electrons and flows in an electrical circuit. Voltage is the potential difference between two points on a circuit. By applying voltage at both ends, the inducement current can be pushed through the circuit.

Generally, batteries have two polarities: positive and negative. Similarly, the 12V speaker has two polarities:

Positive and negative electrodes. Therefore, to connect the 12V horn to the battery, it is necessary to connect the positive pole of the horn to the positive pole of the battery, and connect the negative pole of the horn to the negative pole of the battery. This can be done by using two wires.

One wire will connect the positive pole of the battery to the positive pole of the horn, and the other wire will connect the negative pole of the battery and the negative pole of the horn.

However, there is some preparation that needs to be done before connecting the 12v horn to the battery. First, make sure that the battery is already installed and fastened to its place. Second, determine the negative and positive poles of the horn and make sure that the wires are safely touching them.

Before installing the wires, it is best to clean the surface of the battery and horn connection points for better contact. Finally, make sure that the wire connections are tight to avoid them coming loose when the horn vibrates.

In addition, in order to protect the safety of electrical equipment and users, it is best to turn off the power of the vehicle before connecting the dissipating battery and horn. This avoids short circuits or other electrical problems and ensures that the work is done safely.

In summary, connecting the 12V horn to the battery requires connecting the positive and negative poles of the horn to the corresponding polarity of the battery. This can be done using two pins digging and selling a single wire. Before making the connection, it is important to carry out preparatory work and ensure safe contact of the wires to avoid electrical problems and ensure that the work is completed safely.

24V battery, two in series, then you can connect the power cord from both ends of one battery for 12V car audio. There is an important point that needs to be emphasized, that is, the battery with public grounding is used, otherwise the equipment will fail once the insulation is not good.

According to what you said, your active speaker is with a dual power supply (that is, 12V), so if you want to use only one 12V battery to connect to your active speaker, it is not possible, but if you can use two batteries, then you can let the two batteries be connected in series (that is, the + pole of one battery is connected to the -pole of the other battery) application, the specific connection is: first cut the three wires of the original transformer (2 black and one blue), the wires on the transformer side are not used, wrap them in adhesive tape, and then the common end of the two batteries (+, The pole phase terminal) is connected to the blue wire (the wire on the side of the circuit board), and the remaining two black wires are connected to the remaining two ends of the battery respectively (because there is a rectifier tube on the circuit, so there is no need to divide the positive and negative poles). That's it!

Hello! According to what you sent, this power amplifier can directly use a 12V battery, the negative pole of the battery is connected to GND, and the positive pole of the battery is connected to +12V.

If the power supply of the speaker is also 12 volts, then the battery and the speaker can be wired.

Since it is composed of two 12V batteries, it is easy to connect, directly from the two batteries connected in series on the wire (positive and negative connection) to connect the root wire out of the 12V positive electrode, and the negative electrode is the negative electrode of the 24V battery.

As you say, your active sound.

The box is with a dual power supply (that is, 12V), so if you want to use only one 12V battery to connect to your active speaker, it is not possible to use it, but if you can use two batteries, then you can let the two batteries be connected in series (that is, the + pole of one battery is connected to the -pole of the other battery) application, the specific connection method is: first cut the three wires of the original transformer (2 black and one blue), the wires on the transformer side are not to be used, wrap them with adhesive tape, and then the common end of the two batteries (+, The pole phase terminal) is connected to the blue wire (the wire on the side of the circuit board), and the remaining two black wires are connected to the remaining two ends of the battery respectively (because there is a rectifier tube on the circuit, so there is no need to divide the positive and negative poles). That's it!

1.In general, the audio circuit BAI has a dual power supply DU

A single power supply is not directly interchangeable.

If the amplifier.

DAO back is a set of successful amplifier (2030A, TDA7265, etc.), appropriately modify the number of circuit references, can be driven by a 12V battery, but the output power will be very small, the estimated sound quality can not meet your needs, if you do a good job with a 4R load, the power does not exceed 6W.

2.The problem of high noise when connected to the inverter power supply is estimated to be caused by the electromagnetic interference of the inverter, the ripple of the output voltage and other parameters and the unreasonable connection of the ground wire;

3.The card reader board on the control board is generally 5V power supply, and can be directly powered by a three-terminal regulator such as a 7805 with +12V;

4.For battery-powered audio circuits, if the output power requirements are small, 12V is generally used to directly supply power to TDA2003 TDA7377 and other special automotive power amplifier ICs, and if the output power is large, most of the output power requirements are used to invert into +-25V and other dual power supplies to drive OCL power amplifier circuits.
