    hmmmm jw if you know that the wattage ur tellin us is MAX wattage -- you wont be pushing it at that much

    400 watt sub is 200 rms 400 peek
    800 watt sub is 400 rms 800 peek
    1000 watt sub is 500 rms and 1000 peek

    i would go with the 12 inch rf but dude u can get two damn 12 inch jl w3v2's for less then that on ebay lol

    I can only speak for my own setup when I say this: I had two 400watt RMS 10" subs and the bass was intense. Unless you're going to compete with these subs, any of the options you listed will be a lot of power.

    IMHO the thing you can do to really get the best sound out of whatever you buy is to have it installed well. Dynomat, a box w/proper volume for your subs, ported enclosure or not (up to you). There's nothing worse than having a sweet sub and parts of your car rattling worse than an Michael J. Fox on the maracas.

    Any of your options will keep your c240 bumpin

    if you were to power each sub at the full RMS power, then the SPL you would get at 1 meter away are as follows

    "1000 watt" - 112.5 dB
    "800 watt" - 111.5 dB
    "2 400 watt" - 114.5 dB

    So if you were concerned with just SPL, you'll get the most out of the two 400 watt subs. (assuming they were each powered by their own 200 watt amplification source.)

    You need to ask yourself how much space you are willing to lose? Also are you looking for loud or clean sound?

    If you are not concerned about space, a large 12" ported box or a double 10" box would be good. If you are concerned about space, I would suggest a 12" or 15" single sub in a sealed box. Sealed boxes will give you a tighter bass response, but usually don't hit as low or loud. I have a single 12" in a small sealed box. Granted it's in a hatch, but with 600 watts RMS going to it, it pounds.

    Another key factor is just how loud you want it. I would suggest going with at least 300 watts RMS to get a nice thump. 300 watts won't pound, but it will give you a decent amount of bass to give your system that low end bass. If going with lower wattage, you should probably use a ported box to maximize your what your sub produces out of your amp. If built and tuned properly, you shouldn't notice a significant drop in sound quality, but definately notice a significant jump in volume.

    ^^^ There will not be a huge difference in SPL as long as you design everything properly. 3dB is the minimum audible difference in SPL. So there would be a minimilistic difference even between the 800 watt sub and the 2 400's.

    Those numbers are in a perfect world, and a perfectly designed box. Real world numbers would probably be lower, and closer together.

    First off those numbers are completely subjective. Your setup can generate completely different numbers. In additional, 3dB is certainly not the only audible difference. 3dB represents double the volume. So you would say that you would not notice something that is 75% louder?

    Those numbers are hard physics. Do some research on acoustic gain principals, and the acoustical applications of the inverse square law. You will find a formula that goes 10 log (w1/w0). Add that to the Sensitivity rating (SPL of the driver at 1 watt at 1 meter) and you will get the maximum potential SPL out of the driver.

    3dB is the minimum audible difference. That is the reasoning of the "3dB down point" in crossovers, eq's, DSP's, and the volume knob on your HU.

    You are correct that 3dB represents a doubling of the SPL but that doesn't translate literally to your ear (Apparent loudness) We hear on a logarithmic scale, which means that twice the "volume" is a barely audible difference.

    I guess I have super sensitive ears (which I don't believe), because I had a buddy who went from 140.5 dB to 142.5 dB and I heard a definate difference in how loud it appeared. He had two sets of subs that produced the different dB levels and I was not aware of which was which when he showed me. It turned out the ones that hit 142.5dB were indeed the ones I said were much louder.
