3 speaker how many ohms?

Question

hi i have 3 12 audiobahns they are dual 4 ohm coils
so i can play them at 2 ohms or 8 ohms, how can i wire them together and how many ohms is going to be the result of all 3 speakers together.
I am getting 1 mono block amplifier and don't if to go with a 0.5 1.0 or 2.0 ohms amplifier
thank you

Answer 1

If you wire each one in series, then put the three in parallel, your amp will see 2.66 ohms (assuming resistance instead of impedance). If your amp says it will handle down to a 2 ohm load, you will be fine.

Each speaker would have one + connected to one - and the other two terminals (a + and a - for each spkr) would be connected with all three +'s together to the amp + and all three -'s together to the amp -.

If your amp will only handle down to a 4 ohm load, I would only use two of the speakers and wire them for 4 ohms. There are two ways to do that, either way is electrically the same.

1. Each speaker with the two coils in parallel, then the two speakers in series with each other, or each speaker with the two coils in series (as described above) and connected in parallel to each other.

Answer 2

Hello... If you wire all 3 speakers in parallel (all positives together and all negatives together) they will be running at .66 ohms. Unless you have a high current amplifier, this will not work without burning up the amplifier. If you Series the subs (positive to one coil, negative to the other coil and a jumper wire to the 2 open connectors) and then run all 3 subs together mono, you will have a 2.66 ohm load. Take into account that ohmages on subs will read higher or lower depending upon the sub maker and the sub. This will work with a 2 ohm mono subwoofer amplifier and will give you good performance. You will have to divide the RMS output power of the amp between the 3 subs to give you the amount of power per sub. Make sure when purchasing an amplifier that you are comparing RMS wattages and not peak powers. Also choose an amplifier that has a low THD (total harmonic distortion) level. These specifications should be listed with the amplifier (RMS wattage and THD) A good thd level would be .1% or lower. Hope this helped!! Good luck and live loud!!!

Answer 3

What you essentially have is 6 4-ohm coils. You can wire these up many different ways, depending on the power you want to drive.
Let's assume you configure your subs for 8 ohms. You can connect them in parallel, and with all 3 subs net a resistance of 2.67ohms(ideal for power, but is a heavy load for most amps). You could connect them in series and net 24 ohms, which would not load your amp too heavily, but you wouldn't get much punch either.
For symmetrical reasons, you might want to just go with 2 of those subs, connect them in parallel, or seperate and in a push-pull configuration. If you mate the speakers front-to-front and oppose the polarity on one of them, you can have a mono- configuration which utilizes 4 coils. That'd be a heavy bass consideration, which is what I'd do.

Answer 4

maximum digital amplifiers won't run a three ohm load without overheating or tripping. An 8 ohm load is generally extra handy to take care of, no longer much less ordinary. regardless of the undeniable fact that, the capacity score skill that the amp will control much less wattage at primary scores. 40 watts at 4 ohms is comparable to 20 watts at 8 ohms, so forth. in straight forward terms a distinctive way of asserting that, to grant the consumer with a much bigger kind to oogle. you would be making use of your eights with in straight forward terms 15 watts, as pronounced right here. for customary volumes on semi compressed (like broadcast radio, or information,) somewhat particularly sufficient. enormously for top performance audio device.. Low efficency audio device, properly no longer so warm, or very loudly, with the potential of quite some clipping interior the wings.

Answer 5

The most efficient way to do this is to put an amp on each sub. Any way you wire all three subs together you are going to have an abnormal impedance load, which is going to be very hard on equipment. Your system will sound much better by putting an amp on each sub. Check out eBay, I have seen some diamond audio sub amps there at some really reasonable prices, 400 watts are around 125 dollars and 800 watts are around 200 dollars. Hope this helps.

Answer 6

Wire them like this http://i81.photobucket.com/albums/j230/sparky3489/TRI-SERIES-DUAL.jpg

This results in a 2.67 ohm load, so the amp you buy needs to be 2 ohm stable and three times the power (watts RMS) as one subs power handling (watts RMS).
