Line out converter or speaker level inputs

One of the reasons I took this route over the pac, is that the LC2i compensates for the stock head unit's bass attenuation. I have seen many people say that when you install a sub with the PAC, that bass attenuation is still there at higher volumes and the bass sounds flabby and weak
That being said, I use the PAC o y stock head unit, and I don't get any rolloff with my sub. It sounds great through the volume range.

unless your system has an amp where the bass rolloff happens, and you install the LC2 before the amp, I don't see how that is possible. The wires coming out of the head unit are carrying the signal that has already been processed, so if the rolloff happens, it happens before the signal hits the wires. If the LC2 can do anything with it, it is artificially adding something that is not there, and it has no way to get it right.

Look up the LC2i, that's exactly what it does, and it does so very well from what I've read. I'm skeptical too but hundreds of excellent reviews are reassuring. The bass isn't exactly "rolled off" with the stock head unit, the full frequency spectrum and signal is still present, its just attenuated, meaning the bass volume level is lowered at higher volume. There is an initial process of tuning the LC2i to your liking, this involves setting the bass level exactly the way you want it at a high volume level. The LC2i then back calculates from this high level in a linear way all the way to 0 volume. Pretty simple, yet pretty genius really
So, would it be possible to put in two LC2i units, one tapped into the front speakers and one into the rears?
And is there a way to adjust the levels so that the tweeter output of the stock system is matched to the amped front and rear speakers?

Just get one of their other models. Im guessing they are called something like LC4i, LC6i etc? Either way there are models that support as many speakers as you want, and they would keep the fade function

That would be possible, however the best thing to do would be to get a lc7i as that costs less than 2 lc2i. you could theoretically use the gain controls on your amps or the LC2i or LC7i to level match to the factory tweeter, however the best scenario would be to use a pair of components in the front and replace the factory tweeter with the tweeter from the component set

I installed a PAC line out converter and spliced it to one of my rear door speakers then tucked all the wires and ran the rca cables to my amp. if you have any questions on that just shoot me a message

im looking to better my current sony system not change it out.....when speakers get crappy than ill think about different ones but until then i would like to use what i paid for

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
