Trump: AG Barr quitting and will leave before Christmas. 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. Without a crossover, the subs will be getting current above what they can play. Some amps are not rated for going lower than 2 ohms, so keep that in mind when bridging an amp. 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. Don’t choose an amplifier based on a power rating at an impedance your subwoofers cannot provide. and should i be able to do it fairly easy if i dont kno much about speakers? Outboard crossovers make more of an impact when you're using them on full range speakers as well. Bridging an amplifier cuts the resistance load (measured in ohms) in half, which can cause it to overheat. Le son sera étrange, la stéréo bizarre, et les graves quasi inexistants ! Just to cite an example, I have two 4-ohm subs wired in parallel, which presents a 2-ohm load to my amp (HiFonics). Username: Themax96se USA Post Number: 21 Registered: Jan-05: Posted on Saturday, January 08, 2005 - 11:52 GMT . Best to bridge amplifers that are specifically designed for it. Ad Choices. Since the sub doesn't move as much as it needs to, it won't cool itself down. 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. 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. why bridge anyway? Bronze Member. 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 allies eye long-shot election reversal move. at least in my experience. Hopefully the amp will have a crossover built in. I have a 1200W Performance Teknique 2 Ch. Since you are not referencing the two seperate channels to ground, your output voltage swing is twice as large. Compare that to 200W if used in stereo, and you see where I'm coming from. 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. 1 decade ago. Seperately they present a 4 ohm load. Wire it with each sub on a seperate bridged channel and it would work perfectly (ie 4ohm woofer, amp sees 2ohms). 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. Sure, they're not as high tolerenced, as intricate, or as bizz-whang as outboards, but they do the same job. The amplifier "sees" the same impedance as in normal hookup, but it needs to be able to handle the extra amounts of voltage/current. Well this is not computer related but at least it has something to do with audio View image: /infopop/emoticons/icon_smile.gif. ?Is it 400 W RMS or 200W RMS ? This is the same as driving a 1-ohm load with each channel. Bridging your amp combines 2 amp channels into one, giving you more power. First of all, you should make sure that your amplifier can be bridged. 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 … 4) Onboard sub crossovers are just fine. The woofer frequency rated at 30hz - 800hz. 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. My amp is a mono block amp but has 2 positive and 2 negative terminals. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. Will I get cancer from a cd player with radio? . You’ll have one going from the switch to the stereo and one from the amp to the stereo. The same with the other sub + ch3 - ch4 that's how to bridge your amp. I twisted the ends of my POSITIVE wires around eachother and placed them in the Channel A Positive. Finally connect the negative end of the second coil to the Bass also isn't nearly as sensitive to crossover quality as high frequencies. the impedence the amplifier sees halfs when you bridge it. © 2021 Condé Nast. Ohms and connect each of the woofers to each of the 2 channels ? They're built from the same components and principles as outboard crossovers. my amp is bridgeable too . ohm. Unless you're a serious audiophile or plan on competing, outboard crossovers are probably overkill. 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've been looking for info. As long as you can wire the subs without going below 4 ohms you'll be ok. 0 0. justincresci. An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. If you don't have an amp already, do yourself a favor and buy something that can run into low impedances. Another thing that has been confusing me is the impedence/resistance of the amps. Since a sub can't physically move fast enough to deal with these upper-frequencies, you're gonna melt that sucker. Parallel it would be a 2 ohm load. 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. 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. Well i'm thinking of putting 2 woofers in my car. Secondly, you have to modify the connections inside the speakon connector attached to the amp's output for bridged mono use. 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 … Put the 30/50 hz filter switch to 50hz... most subs can't deliver a clean30hz signal. You're looking for something that would provide 200x2@4ohm or 400x1@2ohm. I have an Eclipse 34230 which is 370x2@4ohms but due to its design cannot be bridged. Disclaimer on how to bridge an amplifier. i read it on its manual. Put twice as much voltage to your load, and your power will also double. The woofer datasheet does mentioned about box size in single woofer but i'm planning to combine 2 woofers in one box. To bridge, begin by connecting the amplifier to the speaker. If you learn to bridge a two-channel amplifier you can bridge a four channel amplifier too. 2 Ohms each, at least thats what the box says. amps are pretty hardy equipment, especially if you can get one stable down to 1/2ohm or less. How loud is a 24,000 watt system with 3 18's? Ars may earn compensation on sales from links on this site. For a 2-channel amplifier, you will see four terminals. 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. Which is salely bridgeable. I realized that yesterday when trying to hook up 3 different types of amps, to 3 different sub combos. doesn't sound like you have the amp yet, so why not just get a decent 2 channel amp to fit your needs?
