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). 1 & ch. Join Yahoo Answers and get 100 points today. 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. This matters because amps have to provide more current at lower loads (generally). Put the 30/50 hz filter switch to 50hz... most subs can't deliver a clean30hz signal. LouieV. Sure, they're not as high tolerenced, as intricate, or as bizz-whang as outboards, but they do the same job. Another thing that has been confusing me is the impedence/resistance of the amps. Yes it will generate more power but you need to make sure that your amp can drive a 1 Ohm mono load. 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 you wire 2 sub together in parallel (+ to + and - to -) then to your amp, you'll get a 2 ohm load. the ones within an amp are junk and don't do a very good job. They're built from the same components and principles as outboard crossovers. . ?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. 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. 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. ?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). Don’t choose an amplifier based on a power rating at an impedance your subwoofers cannot provide. 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. 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. 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. input switch that shouldn’t be needed. . Seperately they present a 4 ohm load. 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. That's just plain silly. I guess most 2 & 4 channel amps cannot run a 2ohm load BRIDGED? 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. amp. Just to cite an example, I have two 4-ohm subs wired in parallel, which presents a 2-ohm load to my amp (HiFonics). 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. Some amps are not rated for going lower than 2 ohms, so keep that in mind when bridging an amp. Trump: AG Barr quitting and will leave before Christmas. 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? 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? as already stated you need to provide more info about the subs and amp. Il n'y a aucun danger pour l'ampli ni pour les enceintes. i will have help and im not that stupid but i dont wanna buy an amp that will suck if i can bridge it You're looking for something that would provide 200x2@4ohm or 400x1@2ohm. Surely the box size volume will be different. 1) Always, always, always, ALWAYS (Always?) if an amp is bridged at 4 ohms, it is the equivilant of running both channels at 2 ohm individually. Can anyone point me to a particular webpage? Well this is not computer related but at least it has something to do with audio View image: /infopop/emoticons/icon_smile.gif. 2. Yes. The woofer frequency rated at 30hz - 800hz. i would definately cast my vote for getting a crossover outside the one that may be included in the amp. 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. The amplifier "sees" the same impedance as in normal hookup, but it needs to be able to handle the extra amounts of voltage/current. Which is salely bridgeable. i read it on its manual. 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. 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. This is the same as driving a 1-ohm load with each channel. 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). 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 if i connect two 200W RMS woofer in parallel, what is the amps output so that it can drive both amps. Connect the ch. I have two 12" Kicker CVRs. I blew a few fuses, and … As long as you can wire the subs without going below 4 ohms you'll be ok. 0 0. justincresci. 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 … can anybody help me in doing … Without a crossover, the subs will be getting current above what they can play. A JBL BP300.1 would probably do the trick (JBL apparently underrates their amps - it's rated 300x1 @ 2 ohm, but testing shows ~400w). 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.? 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. Since you are not referencing the two seperate channels to ground, your output voltage swing is twice as large. It can also cause balance problems (you don't want too many speakers playing the same frequency range). Basically, the main process is the same for every single channel. If its not designed for bridging, you can run into all kinds of problems. (Car Audio) Does the Kenwood KDC-BT362U receiver have a remote amp on lead. Then connect each half of the cut remote wire to each of the 2 connections on a toggle switch. amps are pretty hardy equipment, especially if you can get one stable down to 1/2ohm or less. You'll have to move the -1 connection to the +2 connection. Get your answers by asking now. It gets kind of complicated, but usually higher dB rolloffs are better for subwoofers (ie 12dB vs. 18dB vs. 24dB). In most cases, a single power cable is the most elegant solution. 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? Hopefully the amp will have a crossover built in. Unless you're a serious audiophile or plan on competing, outboard crossovers are probably overkill. Username: Themax96se USA Post Number: 21 Registered: Jan-05: Posted on Saturday, January 08, 2005 - 11:52 GMT .

An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. 1 decade ago. The amp should feel a 4 ohm load total and run just fine assuming you have all the DIP switches set correctly. First, set the amp's DIP switches for Bridged-Mono mode. Let's find out. Thump is thump. 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. Next connect a separate cut of speaker … Subs can and will die this way. As for box size, each woofer should have its recommended volume. How loud is a 24,000 watt system with 3 18's? This should be indicated on the documentation pamphlets that came with the amplifier, or the amplifier itself. Bass also isn't nearly as sensitive to crossover quality as high frequencies. 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. If you don't have an amp already, do yourself a favor and buy something that can run into low impedances. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. If it does it should be fine - you'd want a low pass crossover around 50-120hz (depending on how it sounds). From the speaker wires, connect the positive lead to terminal A and the negative speaker lead to terminal D. I have it bridged/mono, so the amp sees a 2-ohm mono load. A positive and a negative terminal for channel one, and likewise for channel two. 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. For example, a 50 Watts X 2 amp bridged would act as a 200 Watts x 1 amp. 2000 Avalon radio will it for on a 2002 Siena? Ad Choices.
