4 Wire Speaker To 2 Wire [Know A-Z]

To connect the 4 wire speaker to 2 wire you need to follow easy and simple steps. The steps are connecting the speaker cable’s amp end together, checking the wires working condition, and making sure it is working well.

And finally, connect the negative end to the negative end and the positive to the positive end. In this article, we explained the detailed step-by-step guide on how to connect 4 wire speakers to 2 wire speakers. So, let’s start: 

Bi-Amping: Through bi-amping, you can connect your speakers to 2 amps

Bi-wiring or bridging: Bi-wiring allows you to use 1 amp terminal’s two wires, and you can also connect these two wires to 2 speaker terminals. More specifically, using the four-wire process includes bi-wiring.

Bi-Wiring Speakers: The old speaker models have two terminals. On the contrary, the bi-wiring speakers have four terminals. The speaker back’s four connection terminals made the bi-wiring possible. 

These bi-wiring speakers offer two sections of split connections. One section connects with the high-frequency or mid-drivers, and another section connects to the low-frequency drivers.

How To Connect 4 Conductor Speaker Wires To 2 Conductor Speaker Wires [3 Easy Steps]

We will use the Bi-wiring method to connect 4 conductor speaker wires to 2 conductor speaker wires. If you have the appropriate tools in your hand and know the gimmicks, then Bi-wiring is an easy process for you.

In the bi-wiring process, a particular loudspeaker deals with two cables. The loudspeaker uses one cable for the woofer and one for the tweeter. The same amplifier is used to connect both these cables.

Step 1: Connect The Speaker Cable’s Amp End Together

First, remove your speaker terminal’s jumpers. Then purchase the speaker cord’s two sets. At the ends, these speaker cords will be required to connect that will enter your amplifier or receiver. And the part joined with the speaker will be detached.

The speaker connector’s two sets of high-end amplifiers make the connecting procedure easier. Use identical speaker wires for connecting the speakers.

Step 2: Check And Ensure The Wire’s Good Working Condition

Double-check your four speaker wires and make sure they are identical. Ensure the cable’s perfect working condition and inspect the wire properly.

Step 3: Connect Negative To Negative And Positive To Positive

Before plugging the cables into the amp, check and ensure that you connect one speaker cable’s positive end to the other speaker cable’s positive end.

After connecting the ends perfectly with positive to positive and negative to negative, join this perfectly to the cable head. Then finally, insert the connected cable head into your amp.

Before plugging, make sure the cable’s positive side is not connected to the negative side. Your four-wire speaker can get damaged due to the cable’s defect or connecting the cables to the wrong terminals. Moreover, the wrong terminal connection can blow your amp also.

Note: When hooking up your 4 wire speaker system to 2 wire speaker, use the shortest speaker cable. However, even the shortest speaker’s cable length should be enough to endure minimal strain.

Otherwise, it may wear out. The shortest wires ensure a lower possibility of undesired noise.

Why Is 4 Wire Speaker Preferable

Four wire speaker is preferable because it ensures outstanding sound quality and significantly boosts the speaker’s efficiency.

However, this topic is quite controversial as some users state that connecting 4 speakers wire to 2 posts or bi-wiring offers different benefits and objects.

Bi-wiring removes the speaker output’s undesirable distortion. By separating low and high frequencies, bi-wiring reduces the cable’s strain.

As a result, it ensures a more clear flow of signal. When you use the four terminals on a speaker’s set, it essentially divides the woofer and the tweeter’s current.

Why Should You Connect 4 Wire Speaker System To a 2 Wire Speaker?

The 4 wire speaker system has certain drawbacks for which you should connect it to a two-wire speaker.

  • 4 terminal’s bi-wiring requires speaker cables in double quantity
  • Setting up 4 wiring speaker system is not simple, and it requires time
  • Running four wires with numerous frequencies into one speaker pair can damage your speaker

Things You Need To Consider While Connecting 4 Wire Speaker to 2 Wire

  • Don’t attempt to bridge or connect the amplifiers that are not designed to be bridged. It will result in poor-quality sound.
  • In higher ohm, the series running will change the load.
  • Don’t attempt to run your amplification in series if it is safe only for 80hm or 40hm.

Why Do Speakers Have 4 Terminals

For allowing the bi-wiring connections, speakers usually have four terminals. The four wiring speakers provide split connections, and they generate two separate sections.

Firstly one terminal’s set is connected to the high-frequency and mid-drivers. And the other set terminal is connected to the low-frequency drivers.


Can I connect 2 speakers to 1 channel?

Plug the amplifier’s negative terminal into speaker 1’s negative terminal. Hook speaker 1’s negative to speaker 2’s negative. Now plug the amplifier’s positive terminal into speaker 1’s positive terminal. Finally, hook speaker 1’s positive to speaker 2’s positive.

Can you put multiple speakers on one channel?

Yes! You can put multiple speakers in one channel in two ways. Either in series or parallel, you can connect 2 speakers easily to 1 amplifier. Connect the speakers in parallel, which has 8 ohms impedance or more.

How do you connect red and black wires to speakers?

To connect black and red wires to speakers, you need to connect your speaker’s positive terminal posts to the AV receiver’s positive or red terminals. And in the case of the black speaker, terminals do the same.

What happens when you wire speakers in parallel?

When you wire your speakers in parallel, the speaker’s resistance decreases. If you wired two speakers of 8 ohms in parallel, its load result would be 4 ohms. Calculating the resistive load’s effect is very easy, especially when all speakers have some resistance.
