    It is not possible to connect them directly, and the current loop has a great impact on the CD and directly reduces the CD life.

    Since there is no problem with the dual channels of the power amplifier, it will not cause the failure of only mono sound, because the left and right channels of the power amplifier machine work independently, and the power is not enough, it can only be said that the sound is not loud enough, and there is no reason to bring the speaker. Check (provided that there is no problem with a pair of speaker cables):

    1. Assuming that the left channel is loud and the right channel is not loud, the left and right channel speakers are interchanged, or the left channel is loud, which can only mean that the right channel of the power amplifier is abnormal.

    2. Suppose that the left channel is loud, the right channel is not loud, and the left and right channel speakers are interchanged, the left channel is not loud, and the right channel is loud, which can only mean that there is a problem with the speaker of the original right channel.

    This method of proof is simple and the last word. Your explanation is that [the left and right channels of the amplifier and the speaker are normal], and the proof of the speaker is very simple, so, how do you prove that the dual channels are no problem with the amplifier? Again, the same sentence:

    Since there is no problem with the amplifier and speaker, there is no reason not to sound; Since it doesn't sound, it must be a problem with the speaker or the amplifier.

    Theoretically, in the case of the same resistance value, the power of the power amplifier should be more than twice the power of the speaker is more appropriate, which can ensure that the best effect is good, and the power amplifier of different brands is connected to the speaker, and the best effect is also different.

    <> the + (red) of the horn is connected to the left L+ (red) of the amplifier

    The horn's - (black) is connected to the right r- (black) of the amplifier

    In this way, the left and right channels can come out on one speaker.

    Pick up any of the left and right channels.

    Summary. Two-channel can not be connected (input) to a speaker at the same time, it can only be selected from the left and right channels one of the channels to access a speaker, this is the basic common sense of the audio system, such a connection method speaker will be broken, the power amplifier will be broken. There is no such connection method, I really don't know what purpose I want to achieve, it can only be said to destroy the connection method of audio equipment, connect the two positive wires of the speaker together, connect the two negative wires together, and connect to the speaker.

    Two-channel power amplifier board, only one speaker how to connect?

    With a mono output is not the power of the amplifier board drops by half.

    This will basically go down a little bit.

    LR stands for Left and Right Channels, respectively.

    You can pick it up according to your needs.

    No. The high and low tones can only be found when the left and right channels are matched.

    However, it will also be reflected in one of your horns, and the effect is not obvious.

    You draw the line with positive and negative poles, and there is a difference between high and low tones.

    Your ** line is the wiring block of the speaker, this is divided into positive and negative poles, and the wiring also needs to be distinguished.

    There are two speakers on the speaker, generally a tweeter and a mid-woofer. The role of a small horn is that of a tweeter. It is not necessarily that the larger the speaker, the more power is consumed, but the larger the speaker, the more power the medium and low woofer is used. How to judge the quality of the sound.

    The tweeter is the tweeter unit in the speaker, and its function is to reproduce the high-frequency signal output from the crossover (the frequency range is generally 1000Hz-20000Hz).

    A woofer is a type of loudspeaker, which is a transducer that converts electronic signals into sound. The woofer is composed of an electromagnet, a coil, and a horn film, and together with the tweeter and the midrange speaker, it constitutes the car audio.

    Dear, hello, I'm glad to answer for you, multiple full-range speakers in one speaker A: Two 3-inch full-range speakers to make a speaker The sound quality is not the best, the sound quality is average. Here's why:

    One is: the frequency response range of the 3-inch full-range speaker has certain limitations, mainly in the low-end and high-end, mainly in the middle frequency, that is, the vocal effect is not bad. The second is:

    If you use a 3-inch full-range speaker as a speaker, each speaker can use a speaker, and a reasonable design cabinet structure can give full play to the sound effect of the full-range speaker. The third is: the basic principle of making a speaker is to try not to distort and replay the sound effect, the use of multiple speakers is a helpless choice, because a speaker can not take into account the audio of the listening range of the human ear, the use of multiple speakers, tweeters, midrange speakers, woofers are used with each other, in order to make the speaker emit a full-range sound effect, if a full-range speaker can solve the problem of the full range, it is undesirable, but two full-range speakers of the same specification are installed in the same speaker, it is enough to draw a snake, If the structure is not handled well, it will also cause the problem of standing wave interference.

    To sum up, two identical full-range speakers combined with one speaker can not get better sound quality, may not let the effect of a full-range speaker, can not be set up in this way. The smaller the size of the speaker, the worse the bass reproduction effect, and the lower the frequency response range, so if two three-inch national speakers are used as speakers, the effect is still average.

    If the output impedance of the amplifier is 8 ohms, and both speakers are 4 ohms, the two speakers can be connected to the power amplifier in series.

    Both speakers are 8 ohms, so they need to be connected in series before connecting to the power amplifier, and the output power will be slightly reduced after connection.

    The total resistance value of the speaker after connection cannot be less than the output impedance of the power amplifier, otherwise it will threaten the normal operation of the power amplifier or even burn out the power amplifier.

    How the speaker cables are connected.

    1. The active speaker is connected to the computer

    The method of connecting the active speaker to the computer is very simple,You pass a one-point two-point audio cable,Generally plug in the headphone output interface of the computer,Plug in the red and white interface of the speaker on the other side,Connect the power supply to work,Now buy some computer speakers can directly have built-in power amplifier,Plug and play。

    Second, the passive speaker is connected to the computer

    The method of connecting the passive speaker to the computer, some lines and interfaces may not match, and the wiring needs to be soldered. Buy a stereo adapter cable in the electronics market, the jack is the plug, and solder this plug cable with the speaker wire. To put it simply, the plug is connected to a channel of the power amplifier, such as aux ***, etc.

    The plug is inserted into the signal output of the sound card and it is OK. Use a No. 5 battery,Connect the two wires of the speaker to the positive and negative poles of the battery respectively,If you can hear the sound of "crackling" in the speaker by dialing the wire, then the negative terminal of the battery is connected to the ground wire,Otherwise, there should be no sound。 If the left horn sounds, it is the left channel; If it's the right horn, it's the right channel.

    However, if it is a digital connection, only one line is needed, one end is connected to the SDIF output of the sound card, and the other end is connected to the SDIF input of the power amplifier, and the sound quality is better.

    After testing the polarity of the loudspeaker,There are three poles in the stereo plug,They are the ground and the left and right channels,The ground wire of the left and right speakers is uniformly welded to the ground wire of the plug,The other wire is welded to the left and right channels。 There is also a plug shell that can be screwed on. Once soldered, close the plug shell again.

    Connecting a passive speaker to a computer is a process of connecting an amplifier amplifier to a computer.
