ok. man i was hoping you would say no. i'm kinda tired right now so i will start it now nad then fix and finish it tomorrow. here is my warning. WARNING!!!!!!!! i am extremly tired right now and i will fix what i get wrong tomorrow.!!!!!!!!! an ohm is the amount or resistance that an electrical charge experiences while flowing through a source. the lower the number, the lower the resistance. a lower number makes more power. generally most coax and component and pretty much all mid/high speakers are 4 ohm. there are a few exceptions like some of the OZ speakers which are 3 ohm. sub woofers are a different story. they generally range from 1 ohm to 12 ohms per voice coil. what does per voice coil mean? a voice coil is what the current flows over in the speaker and makes it move thus making sound. how do i use a voice coil? easy hook up your speaker wire carrying the current to the voice coil. how do i do that? there are little terminals on most speakers. wheater it is a push button style connecter or a spayde connecter, they are there. there is always 1 posative and 1 negative per voice coil. what is a DVC? DVC stands for Dual Voice Coil. basically it means that you have 2 voice coils on the speaker. What is a QVC? it is a shopping network. or, well, in speaker talk it is a quad voice coil. to figure your ohm load you first have to know which way you will be wiring them. there are three basic ways. series, parallel, and series and parallel at the same time. if you use a combination all speakers have to be done exactly the same way on every speaker. more info below. for every voice coil on the speaker there is a pair of terminals. if it is a DVC, there are 4 terminals. 2 pos and 2 neg. for a quad there are 8. 4 pos and 4 neg. check the terminals on the speaker before automatically assuming that the pos will be next to the neg. on some speakers the pos is next to the other pos. and the negs are next to each other. what are the advantages of using multiple voice coils? more wiring options. why are more wiring options better? How do i figure my ohm load? i will tell you further down. think of it like this. if a company made only 1 product, and they all fit different cars, like an intake only good on a 95 lamborghini diablo that is black, and it could not fit any other car, it would be very unmarketable because of its limited useablity. same kind of thing. if you buy a 4 ohm stable sub amp, that means that you can only bridge it down to 4 ohms, and then you go buy 3 12 ohm speakers, you will be running it at 4 ohms. if you want to get a new amp, you are limited to only 4 ohm stable amps. which there are not very many of. but if you had gotten say 3 DVC's which each had 2 ohm voice coils, you could wire the individual speakers in series, and then wire them together parallel. and that would give you 3 4 ohm speakers running at 4 ohms. with 3 DVC's with each individual vioce coils that are 2 ohms you can run total ohm loads of .33333 ohms, .66666666 ohms, 1 ohm, 2 ohms, 3 ohms, 4 ohms, 6 ohms, and 12 ohms. that is 8 different combinations. depending on your amp there could be a ninth. where 3 single voice coils can be run 3 different ways. 3 12 ohm SVC's can be run 4 ohms, 12 ohms, and 36 ohms. however only one of those is really useable. oh yeah, i forgot. how do i figure my ohm load? your speakers shold come with a manual giving you possible wiring options and possible ohm loads. unless you buy a prefab box. whats a prefab box? a box that comes from the manufacturer with the speakers already inside. not best buy is not a manufacturer. by manufacturer i mean the speaker companys box. like a jl box with jl subs. a mtx box with mtx subs. generally as a rule if yhey don't charge you for the box and the subs seperatly you will be buying a prefab. is a prefab worse than a custom box? it depends on the application. ask me and i will tell you wheather or not it is better. oh yeah, i forgot. how do i figure my ohm load. you can get an currnet meter. these come in useful for many things. around the house, in your cars when trying to see if a fuse is blown or if you are even getting power to the piece of electronic equipment you are trying to install or fix, testing grounds. oh yeah, i forgot. how do i figure my ohm load? if you have SVC's and they wired parallel, the ohm load is exactly what it says on the speaker. if they are wired series, you take the ohm load of the each voice coil, All of the voice coils NEED to be the same when starting out, and you divide that by the number of voice coils. like if you have 2 speakers with SVC's and they are 4 ohms by themselves, you take 4 and divide it by 2. 4/2=2. 2 ohms. the same can be said for a DVC. except instead of 2 speakers, there is only 1. that one speaker with dual 4 ohm voice coils can be run at either 2, 4, or 8 ohms. same thing as 2 speakers. you can run the voice coils either series or parallel. series being both running together at 2 ohms and parallel both running together at 4 ohms. with DVC's you can run dual 4 speaker in series at 2 ohms. and then wire it parallel to another dual 4 also running at 2 ohms, and together they will run 2 ohms. or you can wire them like this. each dvc is wired in parallel, so now you have 2 dual 4's running at 4 each. then wire them series and they will be running also 2 ohms. or you can wire each speaker series and then wire the speakers together series and they will be running 1 ohm. or you can wire each speaker parallel and then wire the 2 together parallel and they will be running 4 ohms. if you don't get it get a calculator and do the math. if you still don't get it get some paper and do the math. if you still don't get it tell me i am a dumbass and i need to explain it better. why are all the different ohm loads necessary? different applications and different amplifiers. sub amps can range for 4 ohm stable to well the furthest i have seen one rated was a 1/32 of an ohm. that is one hellafied amp though and you will need lots of upgrades to the rest of your car for that amp. most sub amps are either 1 or 2 ohm stable though. you can wire your amps lower tahn the manufacturer says it can go, but i would not recommend it for too long. maybe just for a competition. what will happen if i wire my 2 ohm stable amp to one ohm? ruin it any way you look at it and in most cases you will get very bad SQ the entire time. how quickly depends on how loud you listen to the amp. the kenwood 600 watt amp in another thread for example is a 2 ohm stable amp. when i wired it 1 ohm to see if i could get 600 out of it it did three things. overheat, stop working, and made a good fire to cook things with. this is an extreme though. usually if you overload your amp it will just sound bad for a while until it starts to smoke uncontrolabley. which could make it hard to see out the windows. oh and your question about if i go from 4 ohms to 2 ohms, will it double my power? it depends on the amp. if i go from 2 ohms to 1 ohm, will i double my power? it depends on the amp. generally speaking though, on mono block amps that is pretty close to what happens on most of them. what is a mono block amp? and amp with only one channel of out put. basically speaking it is an amp that is already bridged for you. if you have questions about multi channel amps you will have to ask me about specific siteations cuz there are a whloe freakin lot of scenarios that i could go through, and i am sorry but i just worked a 15 hour day and i am tired and i am going to sleep after i check the other threads cuz i am getting bored with this one right now and i hate my a.d.d. cuz it makes me bored after a while no matter what i am doing. dang that was a long sentance. i more than likely coulda made this longer, but why? i mean come on its only 7846 long. isn't that enough?
