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..
you cnat hurt subs from udnerpowering them unless you clip the amp. if its what you say, give us more details please, but for now what i see is, wire the subs in parrallel then each one to each channel of the amp, each sub will be underpowered by 100 watts no big deal, and to wire in parralel wire each sub like this, pos to pos and neg to neg on the SUB then a neg to the eng on the amp and a pos to a pos on the amp, tahts it
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..
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.
