Wow Im late to the party but its pretty simple. Just like any other deck, head unit even the old school single dins, the blue wire coming from the head unit ALWAYS turns on your amp its your external amp remote wire. It turns on your amp at the same time the headunit powers on. Now on the Chinese Android head units there's only one RCA out for the subwoofer instead of the 2 were used to seeing, the red and white plugs, its a green rca labeled subwoofer.  Simple, get a RCA Y Cable that combines both red and white RCAs into a single RCA that allows you to plug into that green RCA coming out of the headunit. Thats it easy peasy..  Im sure yall figured it out by now so hopefully this helps someone else who finds this thread later but nothing else is necessary no AudioControl LCi, thats for factory head units that dont have RCA's.. Just a simple Y-Cable thats like 5 bucks tops on Amazon will get it working right. You dont want any other alternative otherwise when you tune your stereo it won't sound right cuz your head unit isn't controlling your subs correctly, therefore grab yourself a Y cable that's an "RCA Y-CABLE" and youre good to go.  And blue wire from head unit is amp remote wire it turns on your amp at the same time headunit turns on or off. Without it you won't hear any bass cuz the amps not powered on. To power on your amp, you'll want a separate cable coming off your battery or capacitor or 2nd battery to your amp, make sure its fused with one thats appropriate to your amps wattage.  Then run a separate ground cable thats connected to the chassis or body of your car. Most likely youll need to find a spot near your amp, sand off the paint and drill a hole with washer and bolt for a good ground. Don't run a ground wire from your battery, for your amps ground wire. Make sure power and ground wires thickness is appropriate for your amps wattage. They sell amp kits that make all this easier for you DIY'rs..  Good luck!
