how to bridge an amp with 2 subs

You could wire two SVC 2-ohm subs together to form a 1-ohm load powered by a sub amp like this. Can anyone point me to a particular webpage? Make sure your amplifier can be bridged. In terms of amp wiring, that means getting your power straight from the battery. Another thing that has been confusing me is the impedence/resistance of the amps. BUT realize that you can only do this if your sub is a 4ohm sub or a 2ohm Dual Voice Coil (which can be wired in series to 4ohm). I have a 1200W Performance Teknique 2 Ch. if an amp is bridged at 4 ohms, it is the equivilant of running both channels at 2 ohm individually. 2000 Avalon radio will it for on a 2002 Siena? Wire it with each sub on a seperate bridged channel and it would work perfectly (ie 4ohm woofer, amp sees 2ohms).Make sure the amp is built for bridging. Ars may earn compensation on sales from links on this site. doesn't sound like you have the amp yet, so why not just get a decent 2 channel amp to fit your needs? The woofer frequency rated at 30hz - 800hz. How about if i get 100W x 4 channels @4 Ohms amps and bridge it into 200W x 2 channels @ ?? In a bridged amps, what is actually its output impedence/resistance? Put twice as much voltage to your load, and your power will also double. Wire it with each sub on a seperate bridged channel and it would work perfectly (ie 4ohm woofer, amp sees 2ohms). I've seen it happen. cross over your subwoofers. Unless you're a serious audiophile or plan on competing, outboard crossovers are probably overkill. In series or parallel? This means that the speaker will allow for more current to run from your amp to your speaker(s) for a louder sound. 2 Ohms each, at least thats what the box says. Successful bridging depends on there being signal in both the right and left channels of the amp. Hooking two 4 ohm drivers in series to a bridged amp will not gain any power vs. running them off seperate channels. 1) Always, always, always, ALWAYS (Always?) The same with the other sub + ch3 - ch4 that's how to bridge your amp. amps are pretty hardy equipment, especially if you can get one stable down to 1/2ohm or less. Without a crossover, the subs will be getting current above what they can play. The second and third apply when you want to connect two or more amplifiers to your system and use them at the same time, each amp powering a different set of speakers, with one of them usually used for a subwoofer. Bronze Member. 04-23-2008, 12:42 PM. © 2021 Condé Nast. the ones within an amp are junk and don't do a very good job. and should i be able to do it fairly easy if i dont kno much about speakers? Which is salely bridgeable. Read our affiliate link policy. Regardless of where the amp is getting its’ remote turn-on voltage, this will allow you to turn the amp … Is it better for me to get crossovers module or just use the one on the amps. It's important to keep in mind that when you bridge a two-channel amp, the speaker resistance---measured in ohms---is cut in half (i.e., 4 ohms would go down to 2 ohms). Why are standard transmissions better for offroading? So how can you bridge an amplifier? pickering_autoshop. i've looked at Kenwood KAC-PS301T amplifier and it can be bridged into 400W RMS x 1 @?? http://www.amazon.com/Lanzar-MXA282-4000-Watt-2-Ch... and i was wondering how to bridge it to give me maximum power. Thump is thump. I've already figured out that I'm going to wire both in parallel to get the resistance i need on the amp and I know that i can connect speaker 1 to speaker 2 … Best to bridge amplifers that are specifically designed for it. . 3) Don't put wire subs in stereo. can anybody help me in doing … 2 speaker-level inputs. Your amp will see a 2 Ohm stereo load not because its being fooled into it, because it is a 2 Ohm load with that wiring config. are rated at 1 Ohm, 2 Ohms or 4 Ohms. If the amp has 2 channels you should just connect each sub in one channel If you really want to bridge the amp than you have to wire the subwoofers in … i will have help and im not that stupid but i dont wanna buy an amp that will suck if i can bridge it i would definately cast my vote for getting a crossover outside the one that may be included in the amp. Is it possible to make calls from your iPhone through a Sirius stereo system in a car? Those speakon connectors have four pins (+1 -1 +2 -2). With that in mind, you have the option to either run separate power cables for each amp, or a single cable that feeds all of them. as already stated you need to provide more info about the subs and amp. How loud is a 24,000 watt system with 3 18's? It gets kind of complicated, but usually higher dB rolloffs are better for subwoofers (ie 12dB vs. 18dB vs. 24dB). if i buy a 4 channel amp, and 2 subs, and i hook up 2 of the channels to each sub, would that be what they call bridging it? Total Impedance = Sub Imp/# of Subs . Finally connect the negative end of the second coil to the Il n'y a aucun danger pour l'ampli ni pour les enceintes. You'll have to move the -1 connection to the +2 connection. Just to cite an example, I have two 4-ohm subs wired in parallel, which presents a 2-ohm load to my amp (HiFonics). Bridging any kind of amplifier may seem critical moreover tough but once you know the accurate process it won’t be tough any longer no matter how many channels it has. Get your answers by asking now. Outboard crossovers make more of an impact when you're using them on full range speakers as well. Put the 30/50 hz filter switch to 50hz... most subs can't deliver a clean30hz signal. If you don't have an amp already, do yourself a favor and buy something that can run into low impedances. I've never actually bench tested to see how much power it puts out, but not taking any kind of inefficiency into account, this 2x100 amp puts out 800W. Surely the box size volume will be different. For example, a 50 Watts X 2 amp bridged would act as a 200 Watts x 1 amp. It can also cause balance problems (you don't want too many speakers playing the same frequency range). 4) Onboard sub crossovers are just fine. For your amp you can just set the 2/4 channel amp switch to the “2” position, then bridge 2 channels and set the low-pass crossover. power can be calculated if the woofer or amps. Use your modified cable from the amp to the first sub, then just daisy chain to the second sub. For a 2-channel amplifier, you will see four terminals. Connect the ch. This is the same as driving a 1-ohm load with each channel. 3) Since you apparently haven't bought an amp yet, I would suggest buying either a stereo amplifier that provides the correct amount of power per channel and wiring the drivers on seperate channels (since wiring parallel and bridging the amp would require a 1-ohm stable amp, which is pretty pricey usually) or getting a mono amp that is 2-ohm stable and wiring the two subs in parallel. 1 & ch. You tap into the rear left and right factory speaker wiring, and run speaker wires to a speaker-level input plug that comes with the amp. I guess most 2 & 4 channel amps cannot run a 2ohm load BRIDGED? how do i bridge an amp for 2 speakers and 1 sub. all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. In most cases, a single power cable is the most elegant solution. Join Yahoo Answers and get 100 points today. Ad Choices. Hopefully the amp will have a crossover built in. We just want thump. You’ll have one going from the switch to the stereo and one from the amp to the stereo. If i get an amplifier with 200W x 2 channels and bridge it into single mono output, what kind of arrangement for the 2 woofers that will be the best and does not fry the amps.? and the woofer i.e what max. The woofers are rated at 600W (190W RMS)4 Ohm and the size is 12" each i.e Kenwood KFC-W3003 woofer. All rights reserved input switch that shouldn’t be needed. Depending on your particular setup, either one of these options may work out for the best. Next connect a separate cut of speaker … Channel 1 will be labeled A for positive and B for negative while channel 2 will be labeled C for positive and D for negative. Put them in mono. A JBL BP300.1 would probably do the trick (JBL apparently underrates their amps - it's rated 300x1 @ 2 ohm, but testing shows ~400w). Answer: you are talking about strapping and it's completely different. the impedence the amplifier sees halfs when you bridge it. This should be indicated on the documentation pamphlets that came with the amplifier, or the amplifier itself. 2. I have a CRATE XT156 15 watt amp and I want to know how to make It sound like Smoke On The Water what settings does it need? 1 on Capitol Hill, Unhappy soccer player's troll attempt backfires, Relative of woman trampled at Capitol blames Trump, Men in viral Capitol riot photos arrested. My amp is a mono block amp but has 2 positive and 2 negative terminals. Most amps would need to be connected to a signal for the rear channels also but since yours has a 2/4 ch.

They're built from the same components and principles as outboard crossovers. hey i am working on my friends 1967 pontiac le mans, and he just bought a stereo system (2 speakers, a 1000 watt 4 channel amp, and a subwoofer). It's a lot louder than a similarly configured stereo situation. If the amplifier is used, or lacks documentation, go online and check for the specifications on the manufacturer's website. A couple of things:1) You can wire the subs three different ways: seperately (each on a seperate channel), together in parallel, or together in series. ohm. my amp is bridgeable too . So if you have two 4 ohms subs wired in parallel, the system would have an effective impedance of 4 ohms divided by 2 subs for a total impedance of 2 ohms presented to the amp. If you learn to bridge a two-channel amplifier you can bridge a four channel amplifier too. Yes. If you wire 2 sub together in parallel (+ to + and - to -) then to your amp, you'll get a 2 ohm load. If you are bridging this 2-channel amp to one subwoofer, you will connect one piece of speaker wire from the positive terminal of channel 1 to the speaker’s positive terminal. This probably won't damage the woofers, but it will waste power and reduce overall volume (since the amp will be amplifing sound that you don't want to hear). Trump: AG Barr quitting and will leave before Christmas. An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. If its not designed for bridging, you can run into all kinds of problems. Well i'm thinking of putting 2 woofers in my car. Seperately they present a 4 ohm load. Bass also isn't nearly as sensitive to crossover quality as high frequencies. All that energy that is received and not released is dissipated in the voice coil. Before attempting to bridge an amplifier, there are a few things you need to keep in mind. Hi Stu. I twisted the ends of my POSITIVE wires around eachother and placed them in the Channel A Positive. Normally the cables are wired +1 and -1. Yes it will generate more power but you need to make sure that your amp can drive a 1 Ohm mono load. I've been looking for info. The amplifier "sees" the same impedance as in normal hookup, but it needs to be able to handle the extra amounts of voltage/current. A positive and a negative terminal for channel one, and likewise for channel two. Secondly, you have to modify the connections inside the speakon connector attached to the amp's output for bridged mono use. This matters because amps have to provide more current at lower loads (generally). Basically, the main process is the same for every single channel. connect the negative end of the first coil to the positive end of the second coil. Disclaimer on how to bridge an amplifier. Sure, they're not as high tolerenced, as intricate, or as bizz-whang as outboards, but they do the same job. Will it still be 4 Ohms or 2 Ohms?My understanding is the bridged amps output is still at 4 Ohms but is fooled to see a 4 Ohms load (eg.woofer) as 2 Ohms and thus generate more power in which then translate into a good thing View image: /infopop/emoticons/icon_smile.gif, My understanding is the bridged amps output is still at 4 Ohms but is fooled to see a 4 Ohms load (eg.woofer) as 2 Ohms and thus generate more power in which then translate into a good thing View image: /infopop/emoticons/icon_smile.gif. Well this is not computer related but at least it has something to do with audio View image: /infopop/emoticons/icon_smile.gif. From the speaker wires, connect the positive lead to terminal A and the negative speaker lead to terminal D. 2) If you bridge a stereo amplifier, it will see half the impedance presented by the drivers wired to it. Le son sera étrange, la stéréo bizarre, et les graves quasi inexistants ! That's just plain silly. ?I'm also wondering what will happen if higher frequency bass i.e>1 khz signal goes to the woofer and how will it sound like since it is rated for low frequency bass. If an amp doesn't have a rated power output at a certain impedance, it probably isn't stable at that level (ie will overheat/fry).Hooking a two 4 ohm drivers wired in parallel to a bridged amp will probably fry the amp. if you feed it higher frequencies itll sound like ass, as woofersare meant for lows not highs. So if i connect two 200W RMS woofer in parallel, what is the amps output so that it can drive both amps. Your California Privacy Rights | Do Not Sell My Personal Information As long as you can wire the subs without going below 4 ohms you'll be ok. 0 0. justincresci. Series it would be an 8 ohm load. Bridging an amplifier cuts the resistance load (measured in ohms) in half, which can cause it to overheat. Just because your amplifier will do 1,000 watts RMS doesn’t mean it’s the right amp to power two subwoofers that have a power handling of 500 watts each. You're looking for something that would provide 200x2@4ohm or 400x1@2ohm. If you amp is bridgeable you run + sub wire to ch 1 + then the -sub wire to the - of ch 2 of the amp. amp. We don't need seperate bass channels. . An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. at least in my experience. Ohms and connect each of the woofers to each of the 2 channels ? why bridge anyway? LouieV. Parallel it would be a 2 ohm load. How to bridge a 2Ch amp to two subs running at 2ohms? As for box size, each woofer should have its recommended volume. Username: Themax96se USA Post Number: 21 Registered: Jan-05: Posted on Saturday, January 08, 2005 - 11:52 GMT . I have it bridged/mono, so the amp sees a 2-ohm mono load. IE connect a 4 ohm load to a bridged amp, it will act as if it had a 2 ohm load. I have two 12" Kicker CVRs. The first applies if you want to connect multiple amplifiers to a single speaker or pair of speakers, and use only one amp at a time. as to how to get the correct size of woofer box. This is how you can bridge a 4 channel amp to 2 subs: Si on laisse 2 enceintes branchées alors que l'ampli est en mode bridge, les 2 enceintes recevront le même signal (piloté par un seul potentiomètre, l'autre potentiomètre n'ayant aucune influence), mais en opposition de phase. I realized that yesterday when trying to hook up 3 different types of amps, to 3 different sub combos. Since you are not referencing the two seperate channels to ground, your output voltage swing is twice as large. Will I get cancer from a cd player with radio? To bridge your amplifier, locate the amp terminals. The woofer datasheet does mentioned about box size in single woofer but i'm planning to combine 2 woofers in one box.
