speaker system basics image

I received on a trade a box of 3 10" kicker subs (all 400w RMS) and a 500w @ 2 Ohm stable amp. The problem is that one of the subs is a single 2 Ohm voice coil while the other two have dual 2 Ohm coils, and basically, I'm just trying to find the best way to hook them up. When I got them, only the two duals were hooked up, to present a 2 Ohm load total, and a friend of mine said that would damage the third since they're in an open box (share the same air space). Is that true? I am now trying hooking up only one coil on the DVCs and running those in parallel with the SVC in series for a total Ohm load of 3 and while this sounds a little cleaner, it looks like the SVC is moving a lot more (getting more power). I've also been considering running all of the DVC coils parallel and the SVC in series for 2.5 Ohm load or a couple other ways that give me a 1 Ohm load that I'm hoping impedance rise will make it okay for my amp. Anyway, I can't find a formula to tell me how much power will actually go to each speaker in a mixed wiring system and I don't want to possibly damage them or distort the sound by being unbalanced.
Answer
Regardless of how you wire them (to keep the amp stable) the single coil sub will always get more power.
If you were to hook the coils of both DVC subs in parallel for a 1 ohm load, then wire them in series for a 2 ohm load, you could wire them in series with the other sub for a 4 ohm load, but then the two DVC subs would get half the power and the SVC would get the other half.
If you wired both the coils of each DVC sub in series for a 4 ohm load, then ran them in parallel for a 2 ohm load, then in series with the SVC for a 4 ohm load, the two DVC subs are still going to have to share half the power with the SVC sub.
You're best bet is to sell the SVC sub and put that money toward building a box for the two DVC subs.
If you're going to run all of the coils of the DVC subs in parallel to a 0.5 ohm load, then add in the 2 ohms of the SVC sub, you're going to run into another problem.
When loads of different resistance are wired in parallel, the voltage stays the same but the current is split among the loads. When loads of different resistance are wired in series, the current stays the same but the voltage gets split among the loads. The two DVC subs will get get even less power. I know that sounds odd, but when wiring loads in series, the load with the most resistance (the SVC sub) will get more voltage.
Here are the basics. I know they're light bulbs, but it's an AC circuit similar to that of the output of an amplifier.

What is a software program for non-english speakers to learn english?
Je t'aime.
I'm looking for a language software, like audio that can be listened too, that will teach a kurdish badini speaker english. any ideas?
Answer
Language skills are just much much more than only speaking things. Actually, broadening/improving one's language skills is a very broad concept, it should be done in more than one ways at the same time which is highly recommended. One can NOT become better ONLY in one area, say, speaking, one MUST improve skills in ALL dimensions of the language!
Learning language well requires being as active as possible and making the learning as FUN for oneself as possible. Taking lessons is always important, but equally important are these:
1) Listen/watch: Keep listening to internet radio stations like BBC, watch TV shows in English (use only subtitles, NOT voice dubbing in case you are not a native English speaker!), etc.
2) Write/communicate: Try to find discussion forums from the web about things that you find interesting and FUN (music/various artists, hobbies, etc.) and start communicating there with other people using only English. Start using instant messaging systems in case you find some new friends or start emailing them. Please do NOT be afraid of making mistakes or hesitating, because even native speakers do make mistakes and do hesitate at times! The more you enjoy communicating, the better!
3) Buy yourself a proper dictionary, and each time when you see a strange word that you do not understand, look it up. Putting words into their CONTEXT is one of the best ways to broaden one's vocabulary and grammar knowledge, the more you read and write the better. Memorising is NOT the best way to go with learning vocabulary, grammar or any other language areas!
The main point in ANY language learning is to make it as fun as possible for yourself. Try to find topics that INTEREST you, read online newspapers (Times, Guardian, Independent...), listen to BBC/NBC and other radio stations online, if you find a discussion forum for e.g. your favourite hobby or your idols in music do participate there, etc. The key word here is CONTEXT, which means that it is easier to learn new words and their usage as well as grammar when you use/see them in their real CONTEXT. The more you see and hear the new words in their context and the more you use them in your speech & writing, the easier it becomes to remember their meanings and correct spelling. Do NOT be afraid of making mistakes though, because even native speakers do make mistakes and do hesitate at times!
I'm sorry there is NO EASY WAY out with this, one really must develop language skills in ALL these language "levels" or dimensions in order to reach better language skills!!
Last but not least: NEVER EVER use ANY online translators, they are nothing but utter rubbish!! English is practically EVERYWHERE in the online world these days, you just have to use your imagination to find it! Learning pace is always personal, it takes the time it takes so there is no reason to hurry it up too much. If you do, you will not learn so well. Also, please learn the basics of the standard English first before advancing to finer details like dialects/accents. A word of warning though: Do stay well away from overrated, overpriced and overhyped language "gimmicks" such as Rosetta Stone, they really are NOT worth for checking out!
Good luck!
