Adding a resistor instead of a DVC sub?

Hey.

I would like to know if it is OK to put in a resistor to drop down the load that an amp sees for an SVC sub.

Here's my situation:

I have a JL 10W0 (4 Ohm SVC for those who dont know) in a small sealed box (.75 cubes).  I also have a Memphis Audio MC250D which puts out 125W @ 4 ohm and 250W @ 2 ohm.

I would like to be able to have the amp see 2 ohm.  Can I put a 4 ohm resistor in parallel with the sub? I've been told that this is a bad thing to do because the resistance of a voice coil changes as the sub plays and a resistor is a very solid number, no matter what.

My question is: will this be an OK thing to do to my amp? I dont want to abuse my amplifier, but I do want to get a lot of power to my small sub.

Yes, I know that JL doesnt approve of this kind of power to this sub in particular, but I am fine with the consequences.

Thanks

Ketel is right, if you put a resister in parallel with your sub, then the amp will put out 250 watts as advertised, but 125 of it will go to your resister, which does nothing except generate heat and shorten your amp life by running more current through it.  You will get no more power to your sub and you may indeed harm your amp.

DON'T do it.
