Hi,,, im still trying to find an answer to this million dollar question.
How to I get full range sound out of my factory system to hook my aftermarket sub up to. The factory sub leads dont contain low freq. a 12" sub needs.

I'm not a pro but I just put this in my 2013 Jeep Rubicon and it is driving a 10" sub. Sounds great and is inexpensive. It is designed to work with amplified head units.

The factory sub in the rear deck will play as low as it can. If your subwoofer isn't getting low enough, try re-designing its enclosure.

That is a good question. Also does anyone know if there are sub leads if the factory system didn't come with one? I can't find them if they're there.

also curious if the sub wiring is present in a car without a sub from the factory.

Pretty sure it isn't there, but if it is, its an empty circuit.

I am reading this as you want to add a sub to your factory system that doesn't have a sub line, Right? I am also assuming you want to add a amp/sub/enclosure as your goal

If you DON'T have a factory system with the Sub just tap the rear Left and Right speaker signal. It should be full range and easy to get access to. Input those into a Audio Control LC2i to pull off the sub signal that can then be amplified. If you do have the sub line you can still use the LC2i in the same way to add bass control and boost features.



Maybe if you provided some more details on what you are starting with it might make it easier to help.
