4 ohm on dual 4 ohm voice coils

Is there a way that I can hook up a subwoofer that has dual 4 ohm voice coils at 4 ohms? Or is the only ways i can hook it up 2 ohms or 8 ohms?

When you compare an amp and a sub, don't look at the max powers. This will only be reached right before the amp melts or if you car gets hit by lightening. You want to look at the RMS output numbers. With your amp, the bridged output is 800 watts RMS probably at 4 ohms. The max for you sub is peak power. The RMS value is usually about 1/2 the peak value. I looked online, but can't find a RMS calue anywhere. For using this sub and amp combo, your best bet is to make sure you have a single input source. A good way to do this is to use a RCA Y splitter. This will take one input source and split it into the two that you would need. Then wire each voice coil to its own channel. This will give you the 200 x 2 @ 4 ohms, which is right about there the sub RMS is.  Now, because the 400 watts RMS is a guess, I would be careful will the gain levels.

bfog99 that is a bad suggestion. wiring a voice coil to each channel can cause the sub to destroy itself. even with a source from the same place, the amp can have "mistakes" which will cause the voice coils to hit each other, not work together. I speak from experience because i originally had the same ideal and i blew a jlw3v2 within a week of using a setup like that.Quad L Handyman services

Now someone tell me how on one voice coil former, two coils can be hitting each other..... what can happen if a dvc sub is wired out of phase is the voice coil will want to go in two different directions at the same time, in other words it wants to pull itself apart. Now while the differences in output levels between the two channels of an amp are indeed present, it will no doubt cause problems for the subwoofer, thus it is NOT RECOMMENDED. It is definitely not recommended to wire a dvc out of phase between the two coils for the reasons above. Now  there may be some exclusions to this as sometimes the difference between channels is extremely low, the amp is usually controlled by 1 gain for both channels, 1 crossover for both channels and both channels can be fed with the same mono signal. In a case like this you certainly can use a 2 channel amp to power a dvc sub in stereo mode. It is just not a favorite of mine for long term reliability. If the customer has to work with what he has for now, all the power to him, just do it right, but down the road a proper match of equipment is in his future. You guys are right, there are two sides to every issue, just be sure about your advice, even the best (not saying me cause I learn new things every day) can make mistakes.Top Secret, I can tell you but then my wife will kill me.

I think I'm going to try and hook it up at 2 ohms. But my piece of sh*t audiobahn A8002T amp that i bought brand new (not referbished or anything) doesnt work so I have to send it back and wait for it to be repaired or for them to send me a new one. Luckily it was a authorized dealer where I bought it from and it has a waranty. And its good thing I have a amp to use as a back up. My friend is letting me borrow one of his. But yea If the sub breaks (hey it was free) Im planning on getting new subwoofers soon. Prolly around Christmas. Prolly 2 flameQ 12s. Thanx guys.

Forbidden could not have said it any better

why does everyone want to try this 4ohm stereo thing with a dvc. it is exactly the same as series wiring the voice coils to 8 ohm and bridging the amp. safe and easy. i have mentioned this before but noone seems to listen. just do this and feed the signal normally into the amp. you dont have to y-off the imputs even.....Thank you forbidden for saying how unsafe the other way is.
