Sending high-frequency signals to a sub = bad idea. Depending on your particular setup, either one of these options may work out for the best. If you don't have an amp already, do yourself a favor and buy something that can run into low impedances. The woofer datasheet does mentioned about box size in single woofer but i'm planning to combine 2 woofers in one box. Yes it will generate more power but you need to make sure that your amp can drive a 1 Ohm mono load. Then connect each half of the cut remote wire to each of the 2 connections on a toggle switch. why bridge anyway? at least in my experience. my amp is bridgeable too . Ars may earn compensation on sales from links on this site. ?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. Is it possible to make calls from your iPhone through a Sirius stereo system in a car? The same with the other sub + ch3 - ch4 that's how to bridge your amp. We just want thump. 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. I blew a few fuses, and … An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. Use your modified cable from the amp to the first sub, then just daisy chain to the second sub. 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. First, set the amp's DIP switches for Bridged-Mono mode. Will I get cancer from a cd player with radio? Hopefully the amp will have a crossover built in. 2 Ohms each, at least thats what the box says. as to how to get the correct size of woofer box. Trump is trying to get around Twitter's ban, Woman dubbed 'SoHo Karen' snaps at morning TV host, Official: Trump went 'ballistic' after being tossed off Twitter, NFL owner's odd declaration alters job openings rankings, 'Punky Brewster': New cast pic, Peacock premiere date, Clooney: Trump family belongs in 'dustpan of history', Student loan payments pause will continue: Biden official, GOP senator becomes public enemy No. Two SVC 2-ohm subs rated for 750 watts RMS each, 1500 together, will work great with an amp that can put out up to 1500 watts RMS at 1-ohm, like a Memphis PRXA1500.1. 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. So how can you bridge an amplifier? Well this is not computer related but at least it has something to do with audio View image: /infopop/emoticons/icon_smile.gif. Bass also isn't nearly as sensitive to crossover quality as high frequencies. First and Last terminal to bridge the sub ... http://www.diyaudioandvideo.com/FAQ/Wiring/. I realized that yesterday when trying to hook up 3 different types of amps, to 3 different sub combos. 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. This means that the speaker will allow for more current to run from your amp to your speaker(s) for a louder sound. Bridging an amplifier cuts the resistance load (measured in ohms) in half, which can cause it to overheat. This matters because amps have to provide more current at lower loads (generally). 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). This is the same as driving a 1-ohm load with each channel. In series or parallel? [This message was edited by dannymac26 on October 10, 2001 at 17:31.]. (Car Audio) Does the Kenwood KDC-BT362U receiver have a remote amp on lead. Put the 30/50 hz filter switch to 50hz... most subs can't deliver a clean30hz signal. An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. 2 speaker-level inputs. i read it on its manual. Total Impedance = Sub Imp/# of Subs . A JBL BP300.1 would probably do the trick (JBL apparently underrates their amps - it's rated 300x1 @ 2 ohm, but testing shows ~400w). Finally connect the negative end of the second coil to the Connect the ch. That's just plain silly. 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. A positive and a negative terminal for channel one, and likewise for channel two. Yes. To bridge the amp, connect the subwoofer or bridged speaker positive (+) terminal to the positive amplifier bridged terminal label, and the speaker negative (-) terminal to the negative bridged amplifier terminal also. i will have help and im not that stupid but i dont wanna buy an amp that will suck if i can bridge it Read our affiliate link policy. So I need help with connecting my 2 subs a my amp. Bronze Member. Parallel it would be a 2 ohm load. power can be calculated if the woofer or amps. and the woofer i.e what max. 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. If you wire 2 sub together in parallel (+ to + and - to -) then to your amp, you'll get a 2 ohm load. Surely the box size volume will be different. I guess most 2 & 4 channel amps cannot run a 2ohm load BRIDGED? If its not designed for bridging, you can run into all kinds of problems. 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. 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. i've looked at Kenwood KAC-PS301T amplifier and it can be bridged into 400W RMS x 1 @?? In a bridged amps, what is actually its output impedence/resistance? Wire it with each sub on a seperate bridged channel and it would work perfectly (ie 4ohm woofer, amp sees 2ohms). Most amps would need to be connected to a signal for the rear channels also but since yours has a 2/4 ch. Ad Choices. the ones within an amp are junk and don't do a very good job. From the speaker wires, connect the positive lead to terminal A and the negative speaker lead to terminal D. 1 decade ago. it wont hurt anything, but itll take more power to get the same hit inthe low frequencies, as youre wastin power on frequencies the speaker isnt goingto reproduce, damn it...almsot theexact same post, but you beat me toit, View image: /infopop/emoticons/icon_razz.gif, If a bridged amps "see" a 4 Ohms woofer as 2 Ohms, will it fry the amps? I have a 1200W Performance Teknique 2 Ch. Il n'y a aucun danger pour l'ampli ni pour les enceintes. In terms of amp wiring, that means getting your power straight from the battery. Thump is thump. Trump allies eye long-shot election reversal move. Well i'm thinking of putting 2 woofers in my car. For a 2-channel amplifier, you will see four terminals. The amp should feel a 4 ohm load total and run just fine assuming you have all the DIP switches set correctly. Since a sub can't physically move fast enough to deal with these upper-frequencies, you're gonna melt that sucker. Just to cite an example, I have two 4-ohm subs wired in parallel, which presents a 2-ohm load to my amp (HiFonics). 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. 3) Don't put wire subs in stereo. i would definately cast my vote for getting a crossover outside the one that may be included in the amp. Put them in mono. 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. Hooking two 4 ohm drivers in series to a bridged amp will not gain any power vs. running them off seperate channels. 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. All that energy that is received and not released is dissipated in the voice coil. For example, a 50 Watts X 2 amp bridged would act as a 200 Watts x 1 amp. Electoral College confirms Biden is next president IE connect a 4 ohm load to a bridged amp, it will act as if it had a 2 ohm load. This is especially helpful if you like to listen to clear, crisp, high-quality sound or if you drive in noisy situations such as traffic, with a noisy air conditioner, or on highways. Can anyone point me to a particular webpage? Series it would be an 8 ohm load. You could wire two SVC 2-ohm subs together to form a 1-ohm load powered by a sub amp like this. If it does it should be fine - you'd want a low pass crossover around 50-120hz (depending on how it sounds). How to bridge a 2Ch amp to two subs running at 2ohms? Put twice as much voltage to your load, and your power will also double. 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. Unless you're a serious audiophile or plan on competing, outboard crossovers are probably overkill. Those speakon connectors have four pins (+1 -1 +2 -2). I twisted the ends of my POSITIVE wires around eachother and placed them in the Channel A Positive. I have two 12" Kicker CVRs. Basically, the main process is the same for every single channel. my amp is 200 watts at bridged 4 ohms and i want to that can i bridge it with another amp that has a higher power in watts? are rated at 1 Ohm, 2 Ohms or 4 Ohms. It gets kind of complicated, but usually higher dB rolloffs are better for subwoofers (ie 12dB vs. 18dB vs. 24dB). amp. I've been looking for info. the impedence the amplifier sees halfs when you bridge it. Get your answers by asking now. you have 2 channels on your amp and each channel has + and - In order to bridge the amp you connect the positive speaker wire to the + on ch 1, and connect the negative to - on ch 2 and connect them to your sub. doesn't sound like you have the amp yet, so why not just get a decent 2 channel amp to fit your needs? Disclaimer on how to bridge an amplifier. 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 … We don't need seperate bass channels. 1) Always, always, always, ALWAYS (Always?) how do i bridge an amp for 2 speakers and 1 sub. 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. Best to bridge amplifers that are specifically designed for it. 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. The woofer frequency rated at 30hz - 800hz. he was wondering if i could help him install the system, and he said that i would have 2 bridge the amp to install it.

Simple ...your amp will have speaker output terminal like +-+- that is 1234 ...now to bridge to get the max power u have to connect subs with 1 4 (not 1 2 or 3 4 ) i.e. typically, you aren't going to be driving the amp to its fullest all the time so they tend to be able to handle peak output here and there. Sure, they're not as high tolerenced, as intricate, or as bizz-whang as outboards, but they do the same job. LouieV. It can also cause balance problems (you don't want too many speakers playing the same frequency range). If you amp is bridgeable you run + sub wire to ch 1 + then the -sub wire to the - of ch 2 of the amp. The woofers are rated at 600W (190W RMS)4 Ohm and the size is 12" each i.e Kenwood KFC-W3003 woofer. Join Yahoo Answers and get 100 points today. ?Is it 400 W RMS or 200W RMS ?

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. input switch that shouldn’t be needed. Next connect a separate cut of speaker … . 04-23-2008, 12:42 PM. 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. 2. How loud is a 24,000 watt system with 3 18's? Some amps are not rated for going lower than 2 ohms, so keep that in mind when bridging an amp. Seperately they present a 4 ohm load. 2) Bridging an amp in no way fools it. In most cases, a single power cable is the most elegant solution. 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?

I have an Eclipse 34230 which is 370x2@4ohms but due to its design cannot be bridged. Before attempting to bridge an amplifier, there are a few things you need to keep in mind. 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. http://www.amazon.com/Lanzar-MXA282-4000-Watt-2-Ch... and i was wondering how to bridge it to give me maximum power. all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. Username: Themax96se USA Post Number: 21 Registered: Jan-05: Posted on Saturday, January 08, 2005 - 11:52 GMT . if an amp is bridged at 4 ohms, it is the equivilant of running both channels at 2 ohm individually. How about if i get 100W x 4 channels @4 Ohms amps and bridge it into 200W x 2 channels @ ?? Still have questions? Make sure your amplifier can be bridged. cross over your subwoofers. 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). connect the negative end of the first coil to the positive end of the second coil. Compare that to 200W if used in stereo, and you see where I'm coming from. Another thing that has been confusing me is the impedence/resistance of the amps. Answer: you are talking about strapping and it's completely different. Is it better for me to get crossovers module or just use the one on the amps. More bang for the buck, and that's what it's all about. as already stated you need to provide more info about the subs and amp. You're looking for something that would provide 200x2@4ohm or 400x1@2ohm. . Successful bridging depends on there being signal in both the right and left channels of the amp. If the amplifier is used, or lacks documentation, go online and check for the specifications on the manufacturer's website. Your California Privacy Rights | Do Not Sell My Personal Information Le son sera étrange, la stéréo bizarre, et les graves quasi inexistants ! 1 & ch. Why are standard transmissions better for offroading? 4) Onboard sub crossovers are just fine. Trump: AG Barr quitting and will leave before Christmas. My amp is a mono block amp but has 2 positive and 2 negative terminals. Which is salely bridgeable. Regardless of where the amp is getting its’ remote turn-on voltage, this will allow you to turn the amp … 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). and should i be able to do it fairly easy if i dont kno much about speakers? To bridge your amplifier, locate the amp terminals. Since the sub doesn't move as much as it needs to, it won't cool itself down. This is how you can bridge a 4 channel amp to 2 subs: 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.? First of all, you should make sure that your amplifier can be bridged. ohm. Let's find out. Don’t choose an amplifier based on a power rating at an impedance your subwoofers cannot provide. As for box size, each woofer should have its recommended volume. 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? © 2021 Condé Nast. 2) If you bridge a stereo amplifier, it will see half the impedance presented by the drivers wired to it. Secondly, you have to modify the connections inside the speakon connector attached to the amp's output for bridged mono use. As long as you can wire the subs without going below 4 ohms you'll be ok. 0 0. justincresci. They're built from the same components and principles as outboard crossovers. Normally the cables are wired +1 and -1. Without a crossover, the subs will be getting current above what they can play. 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 … The amplifier "sees" the same impedance as in normal hookup, but it needs to be able to handle the extra amounts of voltage/current. 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. It's a lot louder than a similarly configured stereo situation. Subs can and will die this way. amps are pretty hardy equipment, especially if you can get one stable down to 1/2ohm or less. can anybody help me in doing … Hi Stu. Since you are not referencing the two seperate channels to ground, your output voltage swing is twice as large. if you feed it higher frequencies itll sound like ass, as woofersare meant for lows not highs. To bridge, begin by connecting the amplifier to the speaker. pickering_autoshop. You'll have to move the -1 connection to the +2 connection. Bridging your amp combines 2 amp channels into one, giving you more power. I have it bridged/mono, so the amp sees a 2-ohm mono load. 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). 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.
