Possible wiring options?

[AllusiveGold]

Hello all. Any help with this situation would be much appreciated. I recently purchased a Kicker CompVR 12" DVC 2 ohm sub (CVR122).

Here is the issue. The last time I installed a sub and amp in my car, things were simple. You ran the sub to the amp, the amp to the battery and head unit, and bam, done. Now, they don't seem so simple and I am very unsure if I have the right understanding on the wiring.

I also bought an Alpine MRP-M500 amp.

What I need to know is this. Is it possible for me to get the max out of this sub being that it is 2 ohm? Or do I need to exchange it for a 4 ohm? I ask this because for one, I was warned that if I wire this improperly, I could easily damage the amp or both the sub and amp. I would like to achieve the Per channel into 2 ohms: 500W x 1 if possible with the current sub. But if this is not possible, I need to know. 2 ohms at 2 ohms doesn't seem to be a possibility nor does it make sense. MY guess is, I need to exchange the sub for the 4 ohm. But then, if I do, how do I properly wire it up to get the 500?

Sorry for the long post and any obviously stupid question, lol, ANY help on this matter would be greatly appreciated though!

The amp that you have is not stable at 1 ohm. In wiring the voice coils of your subwoofer in parallel, the amp would see a 1 ohm load. You dont want to do this, I cant say from experience that this amp cant handle 1 ohm on good electrical, but even so the sub you have will not like the extra power. On the other hand if instead wiring the coils in parallel you wired them in series, you would see a 4 ohm load which would rob you of potential power. So you want a dual 4 ohm sub to acheive your final 2 ohm load.

So I was right in thinking that I need to exchange the sub for a 4 ohm instead? THANK YOU!! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Yessir you want a dual voice coil 4 ohm sub, with the coils wired in parallel of each other. (red to red, black to black)
