Good Day All, I am new on this Forum. I have a 2006 Skoda Octavia Mk2 with 12 Way “Sound System” in it, It has aftermarket android head unit + aftermarket 4 Channel Amplifier + Aftermarket Subwoofer installed, The factory amplifier has been removed. I noticed the Front Left and Front Right Mid Speakers are not working at all. Looked under the seat and found Lots of Speaker Wires there and Noticed 2 Brown Colour Wires came apart from somewhere and I guess thats the reason for Front Mid Speakers Not Working. Theres no adapter or something like that.. Just wires. 
Can Somebody Help Me In Rigging Back The Wires By Telling Me The Correct Colour Coding Of The Speaker Wires? TIA. 

Hello. Please u can help me with the wiring at amplifier? How u did it? Just a photo enough or cable means. Thank you!!
