what would you choose?

The MTX 5601 is rated at 300@ 4 and 600@ 2

I would guess maybe a 1000max at 2ohms. I would either consider a different amp to maximize your sub amp setup or series at 4ohms and get 300 to maybe 500watts max.

Do not ever just run one voice coil. It's bad for many reasons and not recommended by the manufactures for a reason.

Because when people use one coil it is to get maximum power out of an amp like in this case which in return will blow the sub.

If you have a dvc sub that takes 1000watts total(500 per coil) but your amp will only do the wanted 1000watts at an ohm you can only get by wiring one coil your end result will be a blown voice coil. The sub will play and sound good im sure all the way up to the point you get that burnt smell.

Your other debunked topic only shows that a lot of people use one coil and haven't damaged a sub yet. You could start another topic on how running power wire from your battery through a door jam is a great idea and have plenty of people say yeah they have done it with no problem but that doesn't make it a good idea or debunked. If it was intended to be ran off one coil they/manufacture would be the first to tell you that and how great their product is compared to everyone elses. But the fact that none of  them do probably has a reason behind it.

In this situation running one coil would not end well.

I was wrong about the one voice coil and plesently surprised.

Why wouldn't companies mention that to their customers is crazy. I sent emails to several companies and will post their replies in a few.

It still wouldn't be ideal in his situation because the amp is going to produce about 1000watts. I think it would be cutting it kinda close. If you take into consideration the chance of being borderline on power and not properly setting gains it could led to a short lived voice coil. I would still use cation and consider another amp in the longrun.

Replies from companies on using one voice coil:

Question  Body: I have a KFC-XW1224D dual 4ohm sub and was wondering if the sub is 600watts rms for both coils would it be safe to run 480watts (or 80% of the total RMS)to just one voice coil and not connect the other voice coil? If no, could you explain why? If yes, could you explain why?

Answer: No, you cannot. You always want to stay within a 15% range for optimal performance and less change of damaging either the speaker or amp. Example: If the amp is 100watts RMS, you can use a speaker with an RMS of 115watts. If you’re running 480watts to just one coil, 300watts RMS, you’ll end up damaging the coil.

JBL same question

Answer: Good evening and thank you for your inquiry. The total RMS handling for the sub is 400 watts RMS for both voice coils. Although it is rated at 400 watts RMS, it can handle a bit more power. You would be find with running up to 650 watts RMS to the whole P1224 sub.

question: Ok, so you are say using one voice coil is a bad idea, even with less then reccomended RMS power?

Answer: It would not be recommended.

JL Audio same question

Answer: We always suggest driving both voice coils of a woofer, it won’t cause any difference in performance but, the woofer will be operating the way it was designed to.

BEST ANSWER EVER:

< color=navy size=2 face=Arial>When you put current through turns of wire, a magnetic field is created, this alternating magnetic field is working against the permanent magnetic field generated by the magnets.  The strength of the alternating field is determined by the input voltage and the length of the wire.  The more wire you have, the more field created.

< color=navy size=2 face=Arial>< color=navy size=2 face=Arial>If you only use 1 coil, the field generated will be less than with both coils, but you won’t hurt anything.  70% power is probably a safer level to play, but clean power is always less an issue than clipped power to the sub
