Connect your speaker’s positive terminal to channel one positive terminal (A for Positive).Now connect speakers ( use wires connected to them).Channel 4 > G for positive > H for negative.Channel 3 > E for positive > F for negative.Channel 2 > C for positive > D for negative.Channel 1 > A for Positive > B for negative.Eight terminals on the 4-Channel Amplifier and channels marked as 1,2,3,4,5 ( Each channel has positive and negative terminals (Two Terminals + AND -).Ensure your Amplifier does not overheat when connected to speakers at half capacity. Read: Where to connect remote wire for an Amplifier? How to Bridge 4-Channel Amp Only In 5 Steps?Ĭheck the specifications of your Amplifier to ensure it is bridgeable or not. Be sure your devices are sending compatible signals when you bridge an amp.Cables are needed if you’re connecting an amplifier to another amplifier. For instance, you need speaker cables when connecting a speaker to an amplifier. Cables for a bridge need to match cables for the devices it connects.For instance, a bridge is used when connecting a high-powered amplifier to a low-powered amplifier. Two types of amps can be connected with a bridge.It is possible to have an amp that will give you a heavy, distorted sound, while you may also want an amp that will provide you with a clean, less distorted sound.You will likely want a more powerful amp if you play Death Metal all the time instead of country music.Now divide the result (2x max output voltage) by load impedance.Īmp max power = (Max output voltage)² / load impedance (measured in watts)Īmp max power = (20)² / 4 = 100 Some Considerations Before Bridging An Amplifier!.It would be best if you doubled the maximum output voltage of your car amplifier.Are you interested in finding out how much power your car amplifier is capable of delivering? To get started, follow these steps:.Suppose you have attached a 4-ohm speaker to your Amplifier.Consider an amplifier (having voltage -21 and +21V).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. You get extra power from doubling the load (2 ohms). Most amplifiers have a setting called Bridge Mode or Bridging (to increase the output power by combining more than one channel). You can accomplish this by using car amp bridging (or “Powering off”), a simple and convenient solution. It is possible to resolve audio conflicts by understanding the basics of bridges. Additionally, bridges can help resolve audio problems between devices. There are several uses for bridges, including connecting two different audio systems, connecting a computer to an audio system, and connecting two different power cord types. You will learn how to bridge a 4-channel amp in this article. In that case, you’ll want to look at the 4-channel amps on the market, which allow you to easily switch between the different channels, which is helpful if you have to play various instruments in the same song. Suppose you’re in the market for an amplifier that can handle your car audio and full-range bass needs. Using the Bridge speakers diagram will make it easier for you. But make sure that your Amplifier is bridgeable, as not all amplifiers can be bridged. They have lots of technical info about how impedance and power interact.It is possible to bridge your Amplifier if you have difficulty getting sound through your Amplifier. Go to a site called ''- it deals with car audio and this woofer was made for car audio. You showed 95Wx2 into 2 Ohms- you would need two of these woofers to achieve that. That doesn't mean it will work well with this woofer, though. It may work at low power levels, but it won't survive long if it's cranked.Ĭonsumer audio equipment that is designed to use AC power (meaning it's not made for 12VDC connection) will generally not be designed for 2 Ohms unless it's made for the pro market or one of the brands that actually wants their equipment to be seen as 'better' because it can survive connection to speakers with difficult impedance. When the impedance is cut in half, the amplifier's theoretical power output doubles and if the impedance doubles, the power is cut in half.īridging an amplifier will theoretically cause the power to increase more than cutting the impedance to 2 Ohms but some amplifiers aren't able to hit the magic numbers because of their low cost.Ī bridged amp reacts to the speaker's impedance as if it were half of what it is, which means that connecting a driver with two 4 Ohm voice coils in parallel will probably make it fail, smoke, whatever you want to call it. They have lots of technical info about how impedance and power interact. Click to expand.Go to a site called ''- it deals with car audio and this woofer was made for car audio.
