New member Username: VespianPost Number: 1 Registered: Apr-05 | Well, here it is.. i have bought two 12" 1200 watt (max) subwoofers.. They are dual voice coil, and have an impedance of four ohms. The amp that i got, is two a two channel, 1000 watt, 2 ohm stereo stable amp.. I have a few questions.. first off, am i at risk of underpowering my subs, and destroying the coils in them? Is the amp i have going to be enough power? Im a bit worried about that.. Second.. How the heck am i going to wire them.. i looked all over, and i cant figure out if each coil is rated at 4 ohms, or if the total impedance equals four ohms.. and then how the hell am i suppost to wire it all up to acheive nominal power? Someone help me, please.. Im going insane.. |

New member Username: VespianPost Number: 4 Registered: Apr-05 | I have to look at the amp before i can say what it puts out at a specific ohm rating, i just ordered it.. havent had a chance to look at its birth certificate yet.. |

Bronze Member Username: VespianPost Number: 12 Registered: Apr-05 | lol, and you see my confusion.. I did a lot of recearch on this before i came to this site, and it all left me askign one question.. Is each coil 2 ohms, or 4 ohms.. the speaker said 4 ohm impedance, but is that per coil, or total.. that is all i really need to know, i can figure the rest out.. |
|
Bronze Member Username: VespianPost Number: 13 Registered: Apr-05 | Id be better off just investing in a 1600 watt four channel amp and wiring each coil to one channel.. |
|
New member Username: ChungyAustralia Post Number: 5 Registered: Apr-05 | i think it's 4ohms each coil. Have you check out this link: http://www.lalena.com/audio/faq/wiring/ Did u try asking the seller too? hope all that helps. Good luck mate |

Unregistered guest | Paul, you have some rather low grade stuff, but I've seen some crappy equipment perform pretty good, for the amount spent. Your best bet is to do what Subfanatic told you earlier. If the amp is 2ohm stereo stable, then wire each speaker in parallel, meaning you take the speaker wire leads of each voice coil and connect the positive lead off the left voice coil to the positive lead of the right voice coil and repeat for the negative lead of each voice coil. This will basically allow you to wire the two voice coils of each speaker into one of the two channels of the amp. The technical way to explain it is: if you have one voice coil that is of 4ohm impedence, when wired to an amp. will create a 4ohm load on the amp. However if you have two voices of 4ohm impedence wired to a single channel of an amp. the ohm load created on the amp is cut in half. Creating a 2ohm load on the amp. If a stereo amp. has a 2 ohm load on each of it's two channels that's called a 2ohm stereo load. Which is your amps best operating level. |
