I have a 2011 santa fe with the base stereo. Does anyone know if I'd have to worry about roll off? Also I'll be using my 4 channel kicker key and was curious about the best place to wire the loc for the sub. My plan is to use radio and car side harnesses to avoid cutting anything. I could run the key active off the front channels then wire the loc into the rears. I'm leaning towards running it in 4 channel mode though and in that case I assume I'd tap in before the amp for the loc. I know an lc6i would solve all my problems but I will already be putting an amp behind the dash and don't know how much room I'll have plus it would be nice to save a few bucks
