We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. If you end up putting the subs in series, then you won't get much volume out of the system. Let’s get started. There is nothing you can do to that amp to get it to put out 300W at 4 ohms. the amp is still seeing a 4 ohm subwoofer and is only going to provide 75W to the sub. simple answer is yes, i would have the sub run off of a bridged 2 channel and the speakers wired to their own channel. How do I bridge a woofer when I have one single voice coil and one double voice coil? Keep in mind you can run most 2 channel amps down to a 2 Ohm stereo load to achieve more power. it says something with built in cross overs? A 50Wx2 amp bridged would act as a 200Wx1 amp. Learning the ins and outs of a bridged circuit is important, though, as an improper setup can damage your equipment. What happens when you bridge an amp? You can sign in to vote the answer. Thanks to all authors for creating a page that has been read 228,424 times. If an amplifier is 2 ohm stereo stable (and therefore 4 ohm mono stable), it will produce the same power into a 2 ohm stereo load as it will into a 4 ohm mono load. You get more power and more efficiency- for subs that is. The following diagrams are the most popular wiring configurations. Now if your sub can handle the amp. Each pair of pairs is a bridgeable set, when bridged, you only use the outer screws of the 4 as one channel, and the two middle screws go unused. 2 subs bridged mono, 2000w/cab, still loads of headroom, but you only have 2 cabs so you won't get as much low end extension. Bridging is simply one option. The best you can do is 150 watts to the speaker out of a bridged 4 to 2 channel setup. If you are wiring the coils in series then run a wire from the positive terminal of the first coil (the one wired to the amp) to the negative terminal of the second coil and from the negative terminal of the first coil to the positive terminal of the second. This time it would look like this: 1) Multiply the values. 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. ), you can blow out your amplifier. Where Z is the impedance of a given speaker. 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. In which case would I … The results will display the correct subwoofer wiring diagram and impedance load to help find a compatible amplifier. So when connecting up your left channel you would connect one wire to the front + and the other to the rear -. These 2 terminals are normally the outter most on these 2 channels or the amp will be marked on how to bridge it. They show a typical single channel wiring scheme. 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). It it NOT necessary to bridge a multi-channel amplifier to make it produce maximum power. You could bridge the amp and run the VC's in parallel, as long as the VC's are 4 ohms. If you have one and about to start bridging it, here is the procedure for you. Well, your subs are dual 4 ohm voice coil subs. A very first look at a circuit representation may be confusing, yet if you can read a subway map, you could review schematics. even if you bridge 2 channels (which provides 150W rms at 2 ohms!) Four channels in, two channels out You run a dual RCA cable from the receiver's front left and right RCA outputs. Since it has been wired to a single 4-ohm sub, the amp can deliver 250 watts with a properly set gain to match the sub power rating perfectly. Select your Woofer Quantity and Woofer Impedance to see available wiring configurations. It's not the best way, but if you can get the subwoofer signal to be mono, it should be fine. Note the markings above the connectors. Also, there is the question of whether or not your amp can handle additional speakers. Make sure you read the manual, and if that doesn't work, then contact the company from where you got that stereo. How do you think about the answers? Normally when in bridged mode, you will hook positive from the speaker to positive (usually marked with a circle around it) from one channel in the bridged pair, and the negative (also marked) of the other from the pair. You will need a 4 channel amp to run 2 speakers in bridged mode. Next, connect the negative end of the first coil to the positive end of the second coil. wikiHow's. Normally, an amplifier may consist up to 4 channels. Or would it be bad for the amp?

You would need the owner manual to know for sure. = Ztotal. You should fuse the battery hot at the battery (incase of accidental damage resulting in short circuit) make sure it is rated at the total amps of the unit. Subwoofer types: (SVC = single voice coil) (DVC = dual voice coil), the site has all the possible ways to hook up any sub/amp combo. The best you can do is 150 watts to the speaker out of a bridged 4 to 2 channel setup. Any other questions feel free to email me. If you have four channels (1,2,3,4), you can bridge channels 1 and 2 together, and then bridge channel 3 and 4 together. Bridging amps is a common process in car stereo systems, as it allows for increasing the amp's power output. The phrase actually refers to wiring the sub-woofers up to a bridged amplifier to produce fuller, deeper bass. Experts recommend using two identical subwoofers for optimal sonic quality. either way, how would i go about the wiring for this, i mean the wiring from the sub/speakers to the amp. So say you have two speakers with impedances of 6 Ohms and 8 Ohms. Wire each sub's coils in series ... wire one pos and one neg together on each sub. With Kenwood, there would be a switch to bridge it to 2 channel. (you'll know by looking at the maxx power and WRMS of the sub and the amp). or for it to work would i have to also hook up my back 2 speakers? Join Yahoo Answers and get 100 points today. Remember: 4 Ohm mono is equivalent to 2 Ohm stereo. This generally leads to a superior sonic experience coming from your home or car stereo system. An amplifier is usually bridged to combine two channels to power one subwoofer, or to combine … a 4 ohm sub is going to be 4 ohm, no matter what you do to the amp. Bridging the channels increases the power output. If the dual VC was 2x 4 ohm, that would give 2 ohm; if the SV is 4 ohm, you add the 2 to get 6 ohm.
