Yes, it helps compensate for the rolloff. What everybody is referring to as a "rolloff" isn't actually what happens. A rolloff would filter the lower frequencies, like a high pass filter, but what the stock HU does is attenuate the lower frequencies, meaning it lowers their volume, so the full frequency range is still there. The LC2I uses a simple compressor that brings the volume of the bass frequencies back up at a certain volume threshold set by the user. It takes some tuning but it works very well. So well, that im not even certain the stock HU does any such thing to begin with.
If you tap into your two rear speaker wires under the front running boards, run wires to the LC2i, then from the LC2I into whatever amp you have bought, then from the amp to a subwoofer, you will be very satisfied with the results. Simple and effective

In theory since you have a subwoofer there should be no rolloff or attenuation of the low frequencies. That would defeat the purpose of the sub altogether. The factory amp probably has high pass crossovers for the door speakers instead of using the rolloff that the normal radio uses to protect them

Just food for thought. If you tap into your front speakers for the sole purpose of adding a sub, you can then still have fade control front to rear. You want your sub to maintain the same levels as your fronts and then control the rears as fill.

Thats where LC2I comes into play. It has two purposes, it boosts the signal and provides the amp a good strong, clean signal, it also compensates for the "rolloff" which is really just the decreasing of the lower frequencies as the volume is turned up. I'm pretty certain it uses a simple compressor to bring the bass level back up once you reach a threshold, set by you.

just to give you guys an idea of how effective the LC2i thing is, at least for myself, I actually have the bass on the stock HU set to 3 bars below center, this means the stock speakers are only being used to produce the mid and upper range frequencies, which they are much more efficient for, this allows them to sound clearer and more accurate while the subwoofer takes care of the lower frequencies. I have my sub's amp set at maybe a quarter volume for typical listening, and there is loads of bass on reserve when I want it.

Something I just thought of, with the sony system, you may want to do some research on whether they have a crossover built in to send the lower frequencies to the subwoofer only. In that case you will want to tap into your sub wires to get the full frequency range to your sub
