To create this article, 37 people, some anonymous, worked to edit and improve it over time. Read:Where to connect remote wire for and Amplifier? Now divide the result (2x max output voltage) by load impedance. It is possible to connect a mono-sub connector to subs if only one Amplifier needs to be connected to them. The amplifier channels can also be connected in parallel to the subs using a Y-adapter. The 3rd Channel:The third channel is also the same as the first and second one. Fourth, ensure that the volume on the -4-Channel Amp is turned up. Normally, an amplifier may consist up to 4 channels. Our first choice for connecting four speakers to a two-channel amp is to use series wiring. The information you need to bridge a 4-channel amplifier can usually be found in the Amplifiers manual.

A bridge is an amplifying feature inbuilt into the cars stereo system. 30 Mar, Last Updated on Fishy, you forgot about his question. Your amplifier should state in the owners manual the minimum required impedance (the resistance load a speaker has) for use. if you do not have access to a digital multimeter then you cant really even do anything correctly with your set up. In case you dont have the user manual, a quick internet search including the model number should suffice. Modern car amps are designed in a way such that all 4 inputs will get the same signal and there wont be any problems. If I bridge a 4 channel amp to 2 channels, will I still have - The reason this is possible is that todays car amps have a design in which one of each 2 audio channels is actually inverted (you can also say 180 degrees out of phase) but is normally connected at the output in a non-inverted fashion. If you have a second subwoofer/speaker, connecting it to the amp is as simple and easy as the procedures in step 3. This is called car amp bridging. 4 Apr, Last Updated on Some amps are unbridgeable while some amps, when bridged, arent capable of driving a subwoofer/speaker with an impedance thats less than 4 ohms. Can I connect one dual-coil speaker to a four-channel amplifier? Having the same impedance as the Amplifier is important for a 4-Channel Amp. Amp max power = (Max output voltage) / load impedance (measured in watts). And be sure that the coil is within the range your amp can handle. Why is this best for driving a subwoofer? See the details to do so. It comes with a push-pull mechanism that allows one channel to produce powerful signals opposite of the second channel. All Rights Reserved. Read on to find out how!

What this connection does is it combines the power from the two separate channels, doubling your power output. This is done by connecting the positive signal with the negative signal of the channel, and note that amplifier power is only based on the voltage and impedance of the speaker. Will this be a viable option if every 2 speakers are wired in parallel? To prevent overheating, you need to ensure the system isnt overloaded. In bridge-amping, an additional amplifier is added between the source and the speaker to increase the Amplifiers power output. This time around, youll use speaker output B. With some math, we would find out that our little example amplifier puts out First, you should understand how positive and negative speaker leads differ. If youre looking to bridge a -Channel amp to subs, there are a few tips that will help make the process easier. Additionally, bridges can help resolve audio problems between devices. Also, the Amplifier will overheat and become damaged due to low output power. Once the speakers are hooked up, there will be a switch marked Stereo, Mono, or Bridged.
