![]() Usually, it says stable to 2 ohms which is what the amp can handle. This is impedance and it is applicable to using the stereo normally or in bridge mode (when it is mono). What does that mean?Įvery amplifier comes with a user manual that tells you about the minimum resistance load of a speaker that can be bridged with the amp. If you have the right speaker (which is to do with load impedance), you can do bridging quite easily. If you want to use dual-voice coil speakers, you must first wire them to meet the requirements.If you want to connect more than one speaker then the total must meet the minimum requirements. Every individual speaker must meet the minimum impedance requirements.You might have to strip less than an inch of the insulation of the wires coming out of the speaker to secure them. Connect the positive wires from the amp to the positive lead of the speaker and the same with the negative terminals.If you have a stereo amplifier, you should know that bridging will make it a mono amp.You must make sure that the amplifier is not internally bridged because if it is, it cannot and should not be done manually.If it cannot function, it will overheat and cause problems. You need to check the user manual and make sure that the amp can work at half the resistance load because that’s what happens when you bridge an amp.You can also do this by checking the amplifier’s specs online. Go through the instruction manual to make sure that it’s possible. You need to determine whether or not you can bridge the amplifier.There are a few things to keep in mind before you get started with the process of bridging. So, in the example given the amplifier’s maximum power will be 100 watts.Īmp max power = (20)² / 4 = 100 A Few Do’s and Don’Ts To determine the max power that the amplifier can produce, you must double the max output voltage and divide the result by load impedance.Īmp max power = (Max output voltage)² / load impedance Now imagine it is connected to a 4-ohm speaker. Here’s an example to understand this better.Ĭonsider an amplifier that has voltage rails at -21 and +21 volts. But before that, you must keep in mind that the amplifier has enough load to support the power supply coming in. The power of any amplifier depends on the voltage it produces and the speaker’s impedance. Every amplifier has a specific maximum wattage when it comes to output but by bridging an amp, you can optimize its power. It happens when you connect the positive signal of a channel with the negative of another. This extra power comes from doubling the load which is typically 2 ohms. It is a pretty useful feature to have because it allows you to combine two or more channels to increase the output power. What Is Car Amp Bridging?Ī lot of cars with amplifiers come with a setting called bridge mode or bridging. But before that, you need to know what it means to bridge an amplifier. If you don’t know-how, we’ll tell you all about it. So, you need to make sure that the one you have is built for this feature. You must know that not all amplifiers can be bridged. And many companies and experts actually tell you how to go about it with a bridge speakers diagram which only makes it all the more easier. You just need to connect a few wires and there you have it. And luckily for you, the process itself is not at all complicated. There are a few advantages to doing this with your audio equipment. It is quite tempting because the process ends with the sub receiving a really powerful signal even if in mono.
