Sending high-frequency signals to a sub = bad idea. 3) Don't put wire subs in stereo. Electoral College confirms Biden is next president This should be indicated on the documentation pamphlets that came with the amplifier, or the amplifier itself. To bridge your amplifier, locate the amp terminals. I have an Eclipse 34230 which is 370x2@4ohms but due to its design cannot be bridged. Put the 30/50 hz filter switch to 50hz... most subs can't deliver a clean30hz signal. all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. Finally connect the negative end of the second coil to the as to how to get the correct size of woofer box. That's just plain silly. Basically, the main process is the same for every single channel. 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. 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. As for box size, each woofer should have its recommended volume. In a bridged amps, what is actually its output impedence/resistance? In terms of amp wiring, that means getting your power straight from the battery. the ones within an amp are junk and don't do a very good job. 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. We just want thump. 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. LouieV.

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. The same with the other sub + ch3 - ch4 that's how to bridge your amp. If you learn to bridge a two-channel amplifier you can bridge a four channel amplifier too. 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). 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. Connect the ch. and should i be able to do it fairly easy if i dont kno much about speakers? 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. my amp is bridgeable too . Put twice as much voltage to your load, and your power will also double. Series it would be an 8 ohm load. Yes. Ohms and connect each of the woofers to each of the 2 channels ? I have a 1200W Performance Teknique 2 Ch. 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. ohm. In series or parallel? and the woofer i.e what max. 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? 1 & ch. Parallel it would be a 2 ohm load. 04-23-2008, 12:42 PM. Without a crossover, the subs will be getting current above what they can play. as already stated you need to provide more info about the subs and amp. 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. If the amplifier is used, or lacks documentation, go online and check for the specifications on the manufacturer's website. 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. How loud is a 24,000 watt system with 3 18's? If you don't have an amp already, do yourself a favor and buy something that can run into low impedances. Bridging your amp combines 2 amp channels into one, giving you more power. Bronze Member. 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. i would definately cast my vote for getting a crossover outside the one that may be included in the amp. Most amps would need to be connected to a signal for the rear channels also but since yours has a 2/4 ch. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. I have it bridged/mono, so the amp sees a 2-ohm mono load. Well this is not computer related but at least it has something to do with audio View image: /infopop/emoticons/icon_smile.gif. If you wire 2 sub together in parallel (+ to + and - to -) then to your amp, you'll get a 2 ohm load. ?Is it 400 W RMS or 200W RMS ? Wire it with each sub on a seperate bridged channel and it would work perfectly (ie 4ohm woofer, amp sees 2ohms). Seperately they present a 4 ohm load. Ad Choices. I twisted the ends of my POSITIVE wires around eachother and placed them in the Channel A Positive. if an amp is bridged at 4 ohms, it is the equivilant of running both channels at 2 ohm individually. 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.? Sure, they're not as high tolerenced, as intricate, or as bizz-whang as outboards, but they do the same job. If it does it should be fine - you'd want a low pass crossover around 50-120hz (depending on how it sounds). The woofer frequency rated at 30hz - 800hz. Why are standard transmissions better for offroading? Some amps are not rated for going lower than 2 ohms, so keep that in mind when bridging an amp. i've looked at Kenwood KAC-PS301T amplifier and it can be bridged into 400W RMS x 1 @?? 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? 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. First and Last terminal to bridge the sub ... http://www.diyaudioandvideo.com/FAQ/Wiring/. Get your answers by asking now. 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. You're looking for something that would provide 200x2@4ohm or 400x1@2ohm. 1) Always, always, always, ALWAYS (Always?) 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). Can anyone point me to a particular webpage? Total Impedance = Sub Imp/# of Subs . amp. First, set the amp's DIP switches for Bridged-Mono mode. This is how you can bridge a 4 channel amp to 2 subs: (Car Audio) Does the Kenwood KDC-BT362U receiver have a remote amp on lead. Read our affiliate link policy. 2000 Avalon radio will it for on a 2002 Siena? An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. All rights reserved It gets kind of complicated, but usually higher dB rolloffs are better for subwoofers (ie 12dB vs. 18dB vs. 24dB). A positive and a negative terminal for channel one, and likewise for channel two. connect the negative end of the first coil to the positive end of the second coil. It's a lot louder than a similarly configured stereo situation. at least in my experience. Those speakon connectors have four pins (+1 -1 +2 -2). if you feed it higher frequencies itll sound like ass, as woofersare meant for lows not highs. 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. 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. We don't need seperate bass channels. You'll have to move the -1 connection to the +2 connection. How to bridge a 2Ch amp to two subs running at 2ohms? Compare that to 200W if used in stereo, and you see where I'm coming from. Thump is thump. http://www.amazon.com/Lanzar-MXA282-4000-Watt-2-Ch... and i was wondering how to bridge it to give me maximum power. In most cases, a single power cable is the most elegant solution. Will I get cancer from a cd player with radio? 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. Hi Stu. So if i connect two 200W RMS woofer in parallel, what is the amps output so that it can drive both amps. Hooking two 4 ohm drivers in series to a bridged amp will not gain any power vs. running them off seperate channels. Just to cite an example, I have two 4-ohm subs wired in parallel, which presents a 2-ohm load to my amp (HiFonics). Successful bridging depends on there being signal in both the right and left channels of the amp. 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? This matters because amps have to provide more current at lower loads (generally). power can be calculated if the woofer or amps. Join Yahoo Answers and get 100 points today. If its not designed for bridging, you can run into all kinds of problems. 4) Onboard sub crossovers are just fine. 2) Bridging an amp in no way fools it. I have two 12" Kicker CVRs. 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 read it on its manual. Subs can and will die this way. Depending on your particular setup, either one of these options may work out for the best. First of all, you should make sure that your amplifier can be bridged. input switch that shouldn’t be needed. They're built from the same components and principles as outboard crossovers. . [This message was edited by dannymac26 on October 10, 2001 at 17:31.]. As long as you can wire the subs without going below 4 ohms you'll be ok. 0 0. justincresci. Don’t choose an amplifier based on a power rating at an impedance your subwoofers cannot provide. I've seen it happen. Unless you're a serious audiophile or plan on competing, outboard crossovers are probably overkill. Since the sub doesn't move as much as it needs to, it won't cool itself down. Since a sub can't physically move fast enough to deal with these upper-frequencies, you're gonna melt that sucker. You could wire two SVC 2-ohm subs together to form a 1-ohm load powered by a sub amp like this. how do i bridge an amp for 2 speakers and 1 sub.
