Thanks to all authors for creating a page that has been read 228,424 times. Bridging amps is a common process in car stereo systems, as it allows for increasing the amp's power output. A very first look at a circuit representation may be confusing, yet if you can read a subway map, you could review schematics. 300 watt maxx power depending on the maxx wattage of the speakers. Waste of an amp for 1 sub. You can do it, but keep the level low because you will be pushing the full power of the amp to just one sub. it says something with built in cross overs? If in series (amp - to - 1st sub, + 1st sub to - 2nd sub, + 2nd sub to + amp), you get 8 ohm load. (the numbers are just for reference) Buy a mono subwoofer amp that would give the sub 200w, or bridge a 2 channel amp for slighlty more power than the mono amp, say 220w. 48/14 = 3.43 Ohms (rounded), You can also use an impedance calculator such as this one. the impedence the amplifier sees halfs when you bridge it. This article has been viewed 228,424 times. Theoretically, the output should be 4 times the power of a single channel on the amp. most 4 chanel amp that has bridging capability goes only to 2 chanel. If you really can’t stand to see another ad again, then please consider supporting our work with a contribution to wikiHow. ), you can blow out your amplifier. 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. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. The term "bridging sub-woofers" is a bit misleading. Series wiring and parallel wiring. 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. 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. 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. Most amps will display how to wire this up with the connectors. if an amp is bridged at 4 ohms, it is the equivilant of running both channels at 2 ohm individually. even if you bridge 2 channels (which provides 150W rms at 2 ohms!) This is an example of a 2 channel amplifier running mid range speakers and then a sub configuration. An amplifier is usually bridged to combine two channels to power one subwoofer, or to combine … A 50Wx2 amp bridged would act as a 200Wx1 amp. Now powering multiple component speakers, 4 channel is the way to go. 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. It is (Z1 x Z2 x Z3…) / (Z1 + Z2 + Z3…) =Ztotal. These 2 terminals are normally the outter most on these 2 channels or the amp will be marked on how to bridge it. Locate the specification labels for your system. wikiHow is where trusted research and expert knowledge come together. that way you use all the channels of the amp and you still have the sub gettng enough power to really knock. % of people told us that this article helped them. 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. For this configuration, all subs must be 2 ohm dual coiled and each sub must be at least 1/4 the power handling of the amp @ 4 ohm.-----These are the only methods I can think of right now that will present a 4 ohm load to the amp. Most amps won't do 2 ohms bridged. 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. Please help us continue to provide you with our trusted how-to guides and videos for free by whitelisting wikiHow on your ad blocker. = Ztotal. Learning the ins and outs of a bridged circuit is important, though, as an improper setup can damage your equipment. all amps that are bridgeable you will notice their bridged impedence is double the individual channel impedence. Bridging the channels increases the power output. 4 channel amps were not designed to power subs. $$$ The RMX 5050 may be a better option. At 150 watts you only need 14 gauge stranded wire to feed the speakers. Bridging is simply one option. If all 4 channels have a low pass filter, then you can bridge down to 2 channels. Next, connect the negative end of the first coil to the positive end of the second coil. 12- to 16 gauge speaker wire is recommended for use with subwoofers. You will need a 4 channel amp to run 2 speakers in bridged mode. This time it would look like this: 1) Multiply the values. What are the disadvantages of bridging one or more subwoofers to an amplifier? Is my vehicle compatible with this aftermarket stereo? At 75 watts you could use 18 gauge. Connect the positive end of the first sub's first coil to the positive end of the second sub's first coil. For DVC sub, the wiring is basicly like 2 svc sub for each driver/speaker. Still have questions? We use cookies to make wikiHow great. 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. wikiHow's.

(you'll know by looking at the maxx power and WRMS of the sub and the amp). Normally, an amplifier may consist up to 4 channels. 6 + 8 = 14 Ohms 3) Divide the top by the bottom to find your total impedance. They show a typical single channel wiring scheme. either way, how would i go about the wiring for this, i mean the wiring from the sub/speakers to the amp. You'd set the A channel to HPF and the filter frequency to 60-100hz depending on the quality of your speakers, and you'd set the B channel to LPF and the frequency to about 80hz. The majority of amps on the home theater market are only stable at 4 ohms when bridged. It it NOT necessary to bridge a multi-channel amplifier to make it produce maximum power. 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. Join Yahoo Answers and get 100 points today. By using this service, some information may be shared with YouTube. This generally leads to a superior sonic experience coming from your home or car stereo system. Check the amplifier's owners manual for minimum impedance the amplifier will handle before hooking up the speakers. The formula for finding total impedance for speakers wired in series is Z1 + Z2 + Z3 …. Mono block amps are sub amps. 6 speakers 4 channel amp wiring diagram – A Beginner s Guide to Circuit Diagrams. Unfortunately, you only see about 2/3 to 3/4 of this power. 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. You can sign in to vote the answer. The results will display the correct subwoofer wiring diagram and impedance load to help find a compatible amplifier. Then at the amp end of the cable, you attach a Y-adapter to each RCA connector, so you end up with four RCA connectors to plug into the amp's four RCA inputs. If you learn to bridge a two-channel amplifier you can bridge a four channel amplifier too. So say you have two speakers with impedances of 6 Ohms and 8 Ohms. 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. For example, a 2-channel amplifier rated for 75 watts RMS per channel at 4 ohms may be able to put out as much as 200 watts at 4 ohms into one channel when bridged, which can be very convenient for powering a subwoofer. 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. simple answer is yes, i would have the sub run off of a bridged 2 channel and the speakers wired to their own channel. Attach + to + and - to - on the dual voice coil, then + to + amp on the single, - (single) to + (double), then - (double) to - amp. Whould this cause a lot of strain on my sub I'm hooking it up to? So when connecting up your left channel you would connect one wire to the front + and the other to the rear -. This number is usually the same as the combined power of the 2 channels at half the load. Any other questions feel free to email me. You cannot bridge those two channels into one channel; it will end up destroying your amplifier.
