how to bridge an amp with 2 subs

Use your modified cable from the amp to the first sub, then just daisy chain to the second sub. 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). Connect the ch. 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. Disclaimer on how to bridge an amplifier. All that energy that is received and not released is dissipated in the voice coil. 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? 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. Next connect a separate cut of speaker … Is it possible to make calls from your iPhone through a Sirius stereo system in a car? This is the same as driving a 1-ohm load with each channel. Unless you're a serious audiophile or plan on competing, outboard crossovers are probably overkill. Successful bridging depends on there being signal in both the right and left channels of the amp. Finally connect the negative end of the second coil to the Trump: AG Barr quitting and will leave before Christmas. The woofers are rated at 600W (190W RMS)4 Ohm and the size is 12" each i.e Kenwood KFC-W3003 woofer. can anybody help me in doing … 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. as to how to get the correct size of woofer box. Basically, the main process is the same for every single channel. We just want thump. 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.? An amp like you describe would be 100x4@4 ohms and 200x2@2 ohms. Compare that to 200W if used in stereo, and you see where I'm coming from. Still have questions? Ad Choices. 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. Without a crossover, the subs will be getting current above what they can play. Put them in mono. 2) If you bridge a stereo amplifier, it will see half the impedance presented by the drivers wired to it. Bronze Member. 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? 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. Some amps are not rated for going lower than 2 ohms, so keep that in mind when bridging an amp. I twisted the ends of my POSITIVE wires around eachother and placed them in the Channel A Positive. First and Last terminal to bridge the sub ... http://www.diyaudioandvideo.com/FAQ/Wiring/. Just to cite an example, I have two 4-ohm subs wired in parallel, which presents a 2-ohm load to my amp (HiFonics). I've been looking for info. 04-23-2008, 12:42 PM. Outboard crossovers make more of an impact when you're using them on full range speakers as well. The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. The woofer datasheet does mentioned about box size in single woofer but i'm planning to combine 2 woofers in one box. The woofer frequency rated at 30hz - 800hz. ohm. Put twice as much voltage to your load, and your power will also double. As long as you can wire the subs without going below 4 ohms you'll be ok. 0 0. justincresci. Before attempting to bridge an amplifier, there are a few things you need to keep in mind. For a 2-channel amplifier, you will see four terminals. why bridge anyway? 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. at least in my experience. I have two 12" Kicker CVRs. ?Is it 400 W RMS or 200W RMS ? Since the sub doesn't move as much as it needs to, it won't cool itself down. 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 means that the speaker will allow for more current to run from your amp to your speaker(s) for a louder sound. That's just plain silly. 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. 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. Don’t choose an amplifier based on a power rating at an impedance your subwoofers cannot provide. Is it better for me to get crossovers module or just use the one on the amps. Electoral College confirms Biden is next president ?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. Another thing that has been confusing me is the impedence/resistance of the amps. IE connect a 4 ohm load to a bridged amp, it will act as if it had a 2 ohm load. 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. It can also cause balance problems (you don't want too many speakers playing the same frequency range). 2. if you feed it higher frequencies itll sound like ass, as woofersare meant for lows not highs. 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. Sending high-frequency signals to a sub = bad idea. Bridging an amplifier cuts the resistance load (measured in ohms) in half, which can cause it to overheat. Bass also isn't nearly as sensitive to crossover quality as high frequencies. First of all, you should make sure that your amplifier can be bridged. In most cases, a single power cable is the most elegant solution. 1) Always, always, always, ALWAYS (Always?)

If you amp is bridgeable you run + sub wire to ch 1 + then the -sub wire to the - of ch 2 of the amp. and the woofer i.e what max. power can be calculated if the woofer or amps. 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. pickering_autoshop. Your California Privacy Rights | Do Not Sell My Personal Information The amplifier "sees" the same impedance as in normal hookup, but it needs to be able to handle the extra amounts of voltage/current. Total Impedance = Sub Imp/# of 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. Wire it with each sub on a seperate bridged channel and it would work perfectly (ie 4ohm woofer, amp sees 2ohms). Le son sera étrange, la stéréo bizarre, et les graves quasi inexistants ! For example, a 50 Watts X 2 amp bridged would act as a 200 Watts x 1 amp. Series it would be an 8 ohm load. Best to bridge amplifers that are specifically designed for it. 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. I blew a few fuses, and … I have a 1200W Performance Teknique 2 Ch. The amp should feel a 4 ohm load total and run just fine assuming you have all the DIP switches set correctly. How about if i get 100W x 4 channels @4 Ohms amps and bridge it into 200W x 2 channels @ ?? We don't need seperate bass channels. 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.
