For any car audio enthusiast, no sound system really is complete without a killer subwoofer paired with the best accessories. Of course, to power all this Incredible electronics you need a source. This is where your amp comes into play. However, choosing the right amp for your sound system is much harder than it seems. For beginners on the stage it is recommended to choose a set in advance, as the combination of all units can be a difficult task. But hardcore audiophiles who live and Breathe music prefer a more practical approach to working with their music. 

How to Bridge

Crossing means combining the channels of two (four) amplifiers into one (two) channels at twice the voltage. A two-channel amplifier can be converted to one channel and a four-channel amplifier to two. Winning channels increases the output power. Typically, an amplifier is connected to a bridge to connect two channels to receive power from one subwoofer or to combine four channels to receive power from two subwoofers. For the sake of clarity, you cannot change the single block amplifier! A bridge definition connects two or more channels, and a single-block amplifier has only one channel. You need opposite channels to beat the amplifier. Technically, you use low source impedance to control high load impedance, which results in maximum voltage transfer.

Mobile amplifiers have a reverse channel to beat. An inverted channel produces a voltage that is generated by the opposite polarity of a normal, unresolved channel bridge. The bridge amplifier produces almost four times the amount of power as in non-bridge mode.

Before attempting to replace the amplifier, you need to keep certain conditions in mind. Only connect an amplifier that can withstand the increased load. Do not replace an amplifier that is unstable under bridge load or if the speakers cannot withstand the increased power. Always check the documentation and diagrams of your product before installing the amplifier. Using amplifier documents is the easiest way to figure out how to beat an amplifier.

Unless otherwise noted, all multichannel amplifiers have a minimum power stability higher than the minimum declared impedance of one of its channels. For example, a 2-channel amplifier that is stable at 1 ohm per channel will have a resistance of at least 2 ohms if exceeded. In fact, most amplifiers are stable with only a 4-ohm load in a mono / bridge configuration.

Make sure your amplifier can be bridged

This must be stated in the documentation provided with the amplifier or in the amplifier itself. If the amplifier is used or has no documentation, go online and check the specifications on the manufacturer’s website.

  • The bridge amplifier halves the resistance load (measured in ohms), which can cause it to overheat. Be sure to check the manual (or the manufacturer’s website) to see if it has ever been connected to a speaker or if the amplifier can operate on the side with the ohms currently in use.
  • Most amplifiers have a small circuit next to the channels that show the terminals you would use to switch it. If your amplifier does not claim to be able to make a bridge, do not try to bridge it. It may have already been exceeded inside and you may damage the amplifier.
  • Remember that if your amplifier is a stereo amplifier (amplified from both the left and right), if won, it can become a mono amplifier (amplified from one; either left or right).

If we are talking about amplifiers, then one should know how to perform one of the most important operations; overcoming the amp. So what does it mean when the amp is overcome? 

Here we go with some tips with Bridging of Speakers.

Tips to Consider Before Bridging Your Amplifier

Since not all amplifiers can be beat, the first and most important thing you need to consider is what class you are in. This information usually appears in the documents and brochures that come with the amplifier. However, if your amplifier does not have documentation, you can go online to check the specifications.

Second, it should be noted that winning reduces the load on the resistor by either half an ohm; this can quickly cause the amplifier to overheat and turn off. Make sure you look at the instructions carefully and see if your amplifier can actually operate at half ohms as originally intended. Other amplifiers are also internal bridges and do not require additional bridges, so care must be taken.

Bridging Amplifier

Amplifier connection refers to the process of combining two of the four channels into one or two and a half ohm channels. The technology has become very popular among many car owners because it allows amplifiers to send a more powerful mono signal to a subwoofer or speaker. For example, your car has a 2-channel amplifier with 75 watts of power (RMS) for each channel. At 4 ohms, it can produce about 200 watts per channel per channel. 

This is a very versatile way to use a subwoofer. However, the bridge is similar to Fine Art, which requires precision. But before we show you how to beat a car amplifier, here’s a small disclaimer to keep in mind.

Tips to Bridge your Amplifier

If your car has a two-channel amplifier, you should see 4 connectors; two positive and two negative. Channel 1 is marked positive and B negative, while channel 2 is marked C positive and D negative. To start by jumping, connect an amplifier to the speaker.

Connect the positive cable to terminal A and the negative cable to terminal D. You can do this with a Phillips screwdriver to tighten the screws on the speaker wires. Next, insert the cable between the bottom and top of the connector and insert the screws. 

This connection combines all the power from two separate channels and doubles the output power.

Conclusion

Basically, this is the core of the bridge amplifier to get more power. And remember: if you are unable to complete the winning process, it is always advisable to have it done by an expert to do the job correctly. Alternatively, you can simply purchase an amplifier that has already been exceeded to bypass the process. Finally, always check the properties of the amplifiers to make sure they can be beat.
