If wiring in parallel, connect the negative end of the first sub's second coil to the negative end of the second sub's second coil. A 50Wx2 amp bridged would act as a 200Wx1 amp. With Kenwood, there would be a switch to bridge it to 2 channel. How do I stop a new stereo amp from locking on protection mode with the first hard hit on bass? if an amp is bridged at 4 ohms, it is the equivilant of running both channels at 2 ohm individually. Connect the positive end of the first sub's first coil to the positive end of the second sub's first coil. 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. This is an example of a 2 channel amplifier running mid range speakers and then a sub configuration. The phrase actually refers to wiring the sub-woofers up to a bridged amplifier to produce fuller, deeper bass. The only practical way to wire those subs with that amp is just the way you have it: connect one 4-ohm sub to each channel. either way, how would i go about the wiring for this, i mean the wiring from the sub/speakers to the amp. 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). The best you can do is 150 watts to the speaker out of a bridged 4 to 2 channel setup. Next, connect the negative end of the first coil to the positive end of the second coil. Bridging amps is a common process in car stereo systems, as it allows for increasing the amp's power output. Now if your sub can handle the amp. Wire each sub's coils in series ... wire one pos and one neg together on each sub. 4 channel amps were not designed to power subs. Pimpster, Ty is right. In which case would I … If you choose to wire the subs in series, connect the negative end of the second coil in the first sub to the positive end of the first coil in the second sub (these circuits can get complicated fast). That gives you one pos and one neg out for each sub. Normally, your 2 channel is running at 4 ohm for each channel. as already stated you need to provide more info about the subs and amp. These 2 terminals are normally the outter most on these 2 channels or the amp will be marked on how to bridge it. it's on the small side to drive a subwoofer, but yes, you can bridge two of the channels (probably the "B" channels with that amp) to drive a small 4 ohm subwoofer, and use the "A" channels to power another pair of speakers. I've got this old 4 channel amp I've had since I was 16 and I'm wondering if it would be a good idea to bridge the amp to one channel. wikiHow is where trusted research and expert knowledge come together. They show a typical single channel wiring scheme. So when connecting up your left channel you would connect one wire to the front + and the other to the rear -. = Ztotal. It's not the best way, but if you can get the subwoofer signal to be mono, it should be fine. wikiHow's. the impedence the amplifier sees halfs when you bridge it. You will need a 4 channel amp to run 2 speakers in bridged mode. Normally, an amplifier may consist up to 4 channels. even if you bridge 2 channels (which provides 150W rms at 2 ohms!) Determine what amplifier to use with your subwoofer system. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. Now wire all those pos and negs together ... you'll be at a 2 ohm load, but that's as good as you're going to get. If you're only using 1 speaker/sub, you run it in Mono. or both? Thus in effect doubling the power each channel, say you amp was 200 watts. Learn the tech tips and tricks that everyone should know!

If it is capable of driving (powering) low impedance loads, then it can be done. Why are standard transmissions better for offroading? You would need the owner manual to know for sure. 48/14 = 3.43 Ohms (rounded), You can also use an impedance calculator such as this one. The amplifier is rated at 300 Watts RMS x 1 Channel at 4 Ohms or 500 Watts RMS x 1 Channel at 2 ohms. it gives you.. 1050w/ch at 8ohms.. better headroom. Finally connect the negative end of the second coil to the negative bridged terminal on the amp. Join Yahoo Answers and get 100 points today. Most amps will display how to wire this up with the connectors. This generally leads to a superior sonic experience coming from your home or car stereo system. Keep in mind you can run most 2 channel amps down to a 2 Ohm stereo load to achieve more power. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. Whould this cause a lot of strain on my sub I'm hooking it up to? But if not you can leave the spare channel unused. It depends on the amplifier. you not using channel 3 - 4 its now a 2 channel amp bridged, your only plugging the rca's into channel 1-2 there r no back speakers or channels 3-4 Create an account or login to comment You must be a member in order to leave a comment Most amps won't do 2 ohms bridged. 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. Now powering multiple component speakers, 4 channel is the way to go. Your amp should have a label near the speaker output jack that indicates the output power (measured in Watts) and the minimum impedance (measured in Ohms). http://www.crutchfield.com/S-TAmvZqGPEq6/learn/lea... Will I get cancer from a cd player with radio? Each screw will have a + or - sign above it, and the two used for 150 watts in bridged mode will probably by circled or highlighted in some way that makes them stand out. ), you can blow out your amplifier. how to bridge 2 svc 4ohm subs - Hey everyone, I just wanted to make sure im going to be doing this correctly.THe amplifier is a Power Acoustik 1600 watt 2 channel amplifier. Experts recommend using two identical subwoofers for optimal sonic quality. Attach + to + and - to - on the dual voice coil, then + to + amp on the single, - (single) to + (double), then - (double) to - amp. We use cookies to make wikiHow great. These terms refer to two ways of routing the speaker wires to your … Unfortunately, you only see about 2/3 to 3/4 of this power. So in theory, you could run 2 subs, one off each channel output. At 150 watts you only need 14 gauge stranded wire to feed the speakers. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. If you look at the amp it will probably be 2 pairs of screws side by side, then some adjustments, then 2 more sets of screws. So say you have two speakers with impedances of 6 Ohms and 8 Ohms. Thanks to all authors for creating a page that has been read 228,424 times.
