Marty November 3, at am. This means they have a switch normally on the back panel — but sometimes inside which allows you to tell it you are connecting 2, 4 or 8 pairs of speakers to the one amplifier. Parag nyc, usa. It depends on the impedance of the speakers, or the electrical load the speaker puts on the amp. For a practical discussion on how to wire just 2 speakers to an amplifier 4 speakers to a stereo amp , see my article on How to connect 2 speakers to 1 amplifier. My question is what would the most effective way to hook this up. This is not normally used for more than 2 speakers. They are normally good for lower powered speakers, and the resistor can get hot at high volume levels. You may notice some different performance depending on what kind of subwoofer you bought and how it performs in that particular sized enclosure.


The speaker ohm rating is an indication of the speaker's AC impedance, which varies with the frequency of the input signal. This variation of the speaker's impedance can be seen on the speaker's spec sheet impedance curve. This is why the spec sheet indicates this speaker to have an 8 ohm "nominal impedance. Most of the speakers are available in alternative ohm ratings usually 4, 8 an 16 ohm versions. This variety allows for more flexibility in matching the overall equivalent impedance of your speaker s to the output impedance of the amplifier. It is important that the output impedance of your amplifier matches the overall equivalent impedance of your speaker s for maximum power transfer and so that you do not damage the amplifier. When using more than one speaker with your amp the equivalent overall impedance changes depending on how the speakers are wired. Speakers also have a wattage rating which indicates how much power from the amp they can handle before being damaged. When you use multiple speakers, the output power from the amplifier will be distributed among the speakers. We recommend using speakers with the same ohm rating in multi-speaker cabinets so that the power is evenly distributed to each speaker.

Speakers contain a long wound loop of wire called hook up speakers in series voice coil. This increases the amount of stress and heat it has to handle.

The recommended speaker impedance ratings are usually listed above the speaker wire posts. A home stereo, for example, may often list ohms dating websites free being ok for use. Also, attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. Two 8 ohm speakers in parallel is equal to 4 ohms total that the amp will see. They ended up with a burned-out amplifier. An amplifier can only handle so much heat and stress before it fails, so be sure to observe these rules.

Be sure you wire speakers to meet the minimum Ohm rating you need. Speakers are different than other devices in that they work using alternating current AC instead of direct current DC.

This is good news! As I mentioned, speakers work by moving a cone back and forth in order to produce sound.

The result is a strange and poor sounding stereo. When speakers are wired the hook up speakers in series of each other sound waves cancel out. When wired the same, sound waves add together for more sound. Speakers that are wired differently sound poor because much of the sound is canceled out. So the most important thing here to remember is to wire speakers consistently the same way as each other. The job of a crossover also called a passive crossoverbecause it use basic capacitors and hook up speakers in series rather than electronics is to restrict the music production each speaker tries to produce.

Unlike standard separate speakers, 2-way and 3-way speakers that have a crossover can only be used in parallel and not in series. This is because unlike separate speakers with no crossovers, in this case many sounds will be filtered out.

What this means is that little to no sound would be produced if another 2-way speaker is connected in series. In some cases, more speakers can be added to increase the amount of volume you can get or to place speakers in more rooms, more locations in your vehicle, and so on. You also may have wondered what would happen if you bought an amplifier with twice the power of your present one.

It increases a few decibels dB for each speaker added. This is because of how the human ear works and the physics of sound, along with how speakers work and how much volume they can produce for a given amount of power. Generally speaking, the human ear will hear a very small amount of visit web page increase for each doubling of acoustic power: about 3 decibels dB.

For most people, the small amount of volume increase you notice when turning up a volume knob 1 notch is somewhere around 3dB. It increases it a very small amount as far as your ears are concerned.

For most people an average and good stereo amplifier can produce enough volume to fill a room or vehicle and turn up the volume from time to time. I like to use 50W or higher per channel as a good rule of thumb when buying an amplifier. Have questions, comments, or suggestions? Be sure to leave a comment below or send me a message.

Thanks very much Marty you as an expert explained yourself clearly so as even a 73 year old I could replace the wiring correctly on my home stereo system. Car or home? What type of speakers? Thanks in advance. Hello, Inge. Hopefully this helps and have a good day! I have 2 Rockford Punch subs in a band pass box. There is a wire connecting the two, then another wire leads from each subwoofer speaker and connects to only one positive and negative square on the side of the box.

Why is that? Hello Eddie. Signs youre an abuser, some boxes were made to run 2 subwoofers in parallel for a 4,2, or 1 ohm load to the amp. It sounds like you have one of those boxes. Well, actually speakers are bridged at the amp, not in the box. You need to match them correctly for whatever Ohms rating your amp has. I wish solving the rear speaker matching troubles. Hi Marty. Glad I stumbled upon this informative article.

I have a Monoprice this web page subwoofer box. Unfortunately my foster dog chewed the subwoofer speaker apart. I ordered a new speaker but here is the problem: the original speaker had two terminals but the new speaker has just one. Why do some speakers have one terminal and others have multiple terminals?

Can I attach both sets of wires from inside the box to the one speaker terminal? Hi Darrin. I assume you mean that the original had four terminals two pair and that the replacement has one pair. Well, you need to know the impedance Ohms rating of one of the voice coils on the original subwoofer, which you can find by measuring it with a test meter set to the Ohms scale.

As long as your new subwoofer is the same or higher Ohms rating, you can connect it to one set of wires in the subwoofer box. You may notice some different performance depending on what kind of subwoofer you bought and how it performs in that particular sized enclosure. Great article Marty. I have a question for you. My Harley has a factory radio with 4 — 2ohm front and rear speakers. I am looking to add two more front lower fairing speakers.

That way my stereo would see 2 ohm resistance for the front and back speakers… any advice would be greatly appreciated…. PS — I am ultimately looking for better sound not necessarily louder…. That depends on one thing, though: Whether or not each original speaker right now has its own channel. My advice would be to try it and see how you like it and if the variant hiv dating free site that is enough.

Any connector in the back panel of my DJ Blu,only two red wires are remarkable, dating lanzelot imdb opinion in the back,how can I connect the energy to the system? That depends on what kind of product you have also. Hello Shibli. Basically, just use speakers with the correct impedance rating. For example, if you have 16 ohm speakers and dating a dominant man stereo is rated for 8ohms, adding a 2nd pair in parallel would give 8 ohms.

I bought a set of Klipsch RF towers. They have 4 speaker terminals on each speaker. I am not running an amp and have a Denon 7. Should I bi- wire these or no? I am running 2 klipsch reference 12 inch subwoofers as well. I honestly want to get all i can out of them. But I personally dont hook up speakers in series bi wiring them will make any difference, but i could be wrong. I plan on setting the crossover around 80hz and see what happens. Any advice is welcome.

Hi Ronnie. The standard setup should sound click at this page fine. Hi Matt. Hey Marty…… Brother I have a serious question for you and I pray you will reply sometime before I get off work today…. But it only runs my 2 subs and 2 6x9s in the rear of the dating example personal best profile. I just got a 2 channel amplifier for the door speakers and the dash tweeters….

But I have no more rca outs on the back of the head unit… Since the 4 rca outs are hook up speakers in series running the rear only…. Can I use the speaker wire from the head unit or hook up speakers in series the wiring harness of the vehicle and wire it to the high end of the new amp for the doors and dash…. My question is what would the most effective way to hook this up.

I greatly appreciate any advise given. I would say it partly depends on the setup you want to use. For example, are the extra speakers going to be used in the front or rear? In your case I would run the 6.
